FIELD OF THE INVENTION
[0002] This invention concerns methods and compositions useful in
the fields of neurobiology, molecular biology, and medicine, as
well as methods for the production of potentially toxic therapeutic
agents and derivatives thereof. The invention also concerns
recombinant clostridial neurotoxins (particular botulinum
neurotoxins), modified versions thereof, and methods of making such
molecules, for use as therapeutic agents, transporter molecules,
adducts, and the like.
BACKGROUND OF THE INVENTION
[0003] Neurotoxins, such as those obtained from Clostridium
botulinum and Clostridium tetani, are highly potent and specific
poisons of neural cells, and other cells when delivered within such
cells for therapeutic purposes. These Gram positive bacteria
express two related but distinct toxins types, each comprising two
disulfide-linked amino acid chains: a light chain (L) of about 50
KDa and a heavy chain (H) of about 100 KDa, which are wholly
responsible for the symptoms of these diseases. The holotoxin is
synthesised in vivo as a single-chain, then nicked in a
post-translational modification to form the active neurotoxin
comprising the separate L and H chains.
[0004] The tetanus and botulinum toxins are among the most lethal
substances known to man, having a lethal dose in humans of between
0.1 ng and 1 ng per kilogram of body weight. Tonello et al., Adv.
Exp. Med. & Biol. 389:251-260 (1996). Both toxins function by
inhibiting neurotransmitter release in affected neurons. The
tetanus neurotoxin (TeNT) acts mainly in the central nervous
system, while botulinum neurotoxin (BONT) acts at the neuromuscular
junction and other cholinergic synapses in the peripheral nervous
system; both act by inhibiting neurotransmitter release from the
axon of the affected neuron into the synapse, resulting in
paralysis.
[0005] The tetanus neurotoxin (TeNT) is known to exist in one
immunologically distinct type; the botulinum neurotoxins (BONT) are
known to occur in seven different immunogenic types, termed BoNT/A
through BoNT/G. While all of these types are produced by isolates
of C. botulinum, two other species, C. baratii and C. butyricum
also produce toxins similar to /F and /E, respectively. See e.g.,
Coffield et al., The Site and Mechanism of Action of Botulinum
Neurotoxin in Therapy with Botulinum Toxin 3-13 (Jankovic J. &
Hallett M. eds. 1994), the disclosure of which is incorporated
herein by reference.
[0006] Regardless of type, the molecular mechanism of intoxication
appears to be similar. In the first step of the process, the toxin
binds to the presynaptic membrane of the target neuron through a
specific interaction between the heavy (H) chain and a cell surface
receptor; the receptor is thought to be different for each type of
botulinum toxin and for TeNT. Dolly et al., Seminars in
Neuroscience 6:149-158 (1994), incorporated by reference herein.
The carboxyl terminus of the heavy chain appears to be important
for targeting of the toxin to the cell surface. Id.
[0007] In the second step, the toxin crosses the plasma membrane of
the poisoned cell. The toxin is first engulfed by the cell through
receptor-mediated endocytosis, and an endosome containing the toxin
is formed. The toxin then escapes the endosome into the cytoplasm
of the cell. This last step is thought to be mediated by the amino
terminus of the H chain, which triggers a conformational change of
the toxin in response to a pH of about 5.5 or lower. Endosomes are
known to possess a proton pump which decreases intra endosomal pH.
The conformational shift exposes hydrophobic residues in the toxin,
which permits the toxin to embed itself in the endosomal membrane.
The toxin then translocates through the endosomal membrane into the
cytosol.
[0008] The last step of the mechanism of botulinum toxin activity
appears to involve reduction of the disulfide bond joining the H
and light (L) chain. The entire toxic activity of botulinum and
tetanus toxins is contained in the L chain of the holotoxin; the L
chain is a zinc (Zn.sup.++) endopeptidase which selectively cleaves
proteins essential for recognition and docking of
neurotransmitter-containing vesicles with the cytoplasmic surface
of the plasma membrane, and fusion of the vesicles with the plasma
membrane. TxNT, BoNT/B BoNT/D, BoNT/F, and BoNT/G cause degradation
of synaptobrevin, also called vesicle-associated membrane protein
(VAMP), a synaptosomal membrane protein. Most of the cytosolic
domain of VAMP extending from the surface of the synaptic vesicle
is removed as a result of any one of these cleavage events. Each
toxin (except TeNT and BoNT/B) specifically cleaves a different
bond.
[0009] BoNT/A and /E selectively cleave the plasma
membrane-associated protein SNAP-25; this protein, which is also
cleaved by BoNT/C1 (Foran et al., Biochem. 35:2630-2636 (1996)), is
predominantly bound to and present on the cytosolic surface of the
plasma membrane. BoNT/C cleaves syntaxin, an integral protein
having most of its mass exposed to the cytosol. Syntaxin interacts
with the calcium channels at presynaptic terminal active zones. See
Tonello et al., Tetanus and Botulinum Neurotoxins in Intracellular
Protein Catabolism 251-260 (Suzuki K. & Bond J. eds. 1996), the
disclosure of which is incorporated by reference as part of this
specification.
[0010] Both TeNT and BoNT are taken up at the neuromuscular
junction. BoNT remains within peripheral neurons, and blocks
release of the neurotransmitter acetylcholine from these cells.
Through its receptor, TeNT enters vesicles that move in a
retrograde manner along the axon to the soma, and is discharged
into the intersynaptic space between motor neurons and the
inhibitory neurons of the spinal cord. At this point, TeNT binds
receptors of the inhibitory neurons, is again internalized, and the
light chain enters the cytosol to block the release of the
inhibitory neurotransmitters 4-aminobutyric acid (GABA) and glycine
from these cells.
[0011] Because of its specifically localized effects, minute doses
of BoNT have been used since 1981 as therapeutic agents in the
treatment of patients suffering from dystonias, including
strabismus (misalignment of the eye), bephlarospasm (involuntary
eyelid closure) and hemifacial spasm. See e.g., Borodic et al,
Pharmacology and Histology of the Therapeutic Application of
Botulinum Toxin in Therapy with Botulinum Toxin 119-157 (Jankovic
J. & Hallett eds. 1994), hereby incorporated by reference
herein. Of the seven toxin types, BoNT/A is the most potent of the
BoNTs, and the best characterized. Intramuscular injection of
spastic tissue with small quantities of BoNT/A has also been used
effectively to treat spasticity due to brain injury, spinal cord
injury, stroke, multiple sclerosis and cerebral palsy. The extent
of paralysis depends on both the dose and volume delivered to the
target site.
[0012] Although the L chain is the moiety responsible for neural
intoxication, it must be delivered to the neural cytoplasm in order
to be toxic. Similarly, the single-chain holotoxin pro-forms
exhibit relatively low toxicity until they are cleaved at one or
more peptide bonds in an exposed loop region between their H and L
chains to create the fully-active mature neurotoxins. As implied in
the mechanism provided above, the H chain of each neurotoxin is
essential for cell receptor binding and endocytosis, while both the
L and the H chains (and an intact disufide bond) are required for
translocation of the toxin into the cytoplasm. As indicated above,
the L chain alone is responsible for the toxicity caused by
inhibition of acetylcholine secretion.
[0013] Despite the clear therapeutic efficacy of clostridial
neurotoxin preparations, industrial production of the toxin is
difficult. Production of neurotoxoin from anaerobic Clostridium
cultures is a cumbersome and time-consuming process including a
multi-step purification protocol involving several protein
precipitation steps and either prolonged and repeated
crystallisation of the toxin or several stages of column
chromatography. Significantly, the high toxicity of the product
dictates that the procedure must be performed under strict
containment (BL-3). During the fermentation process, the folded
single-chain neurotoxins are activated by endogenous clostridial
proteases through a process termed nicking. This involves the
removal of approximately 10 amino acid residues from the
single-chain to create the di-chain form in which the two chains
remain covalently linked through the interchain disulfide bond.
[0014] The nicked neurotoxin is much more active than the unnicked
form. The amount and precise location of nicking varies with the
serotypes of the bacteria producing the toxin. The differences in
single-chain neurotoxin activation and, hence, the yield of nicked
toxin, are due to variations in the type and amounts of proteolytic
activity produced by a given strain. For example, greater than 99%
of C. botulinum type A single-chain neurotoxin is activated by the
Hall A C. botulinum strain, whereas type B and E strains produce
toxins with lower amounts of activation (0 to 75% depending upon
the fermentation time). Thus, the high toxicity of the mature
neurotoxin plays a major part in the commercial manufacture of
neurotoxins as therapeutic agents.
[0015] The degree of activation of engineered clostridial toxins
is, therefore, an important consideration for manufacture of these
materials. It would be a major advantage if neurotoxins such as
BoNT and TeNT could be expressed in high yield in rapidly-growing
bacteria (such as heterologous E. coli cells) as relatively
non-toxic single-chains (or single-chains having reduced toxic
activity) which are safe, easy to isolate and simple to convert to
the fully-active form.
[0016] With safety being a prime concern, previous work has
concentrated on the expression in E. coli and purification of
individual H and L chains of TeNT and BoNT; these isolated chains
are, by themselves, non-toxic; see Li et al., Biochemistry
33:7014-7020 (1994); Zhou et al., Biochemistry 34:15175-15181
(1995), hereby incorporated by reference herein. Following the
separate production of these peptide chains and under strictly
controlled conditions the H and L subunits can be combined by
oxidative disulphide linkage to form the neuroparalytic di-chains.
Unfortunately, this strategy has several drawbacks.
[0017] Firstly, it is not practical to express and isolate large
amounts of the individual chains; in particular, in the absence of
the L chain the isolated H chain is quite insoluble in aqueous
solution and is highly susceptible to proteolytic degradation.
Secondly, the in vitro oxidation of the individually expressed and
purified H and L chains to produce the active di-chain is very
inefficient, and leads to low yields of active toxin and the
production of many inactive incorrectly folded or oxidized forms.
The purification of the correctly folded and oxidized H and L
chain-containing toxin is difficult, as is its separation from
these inactive forms and the unreacted separate H and L chains.
[0018] It would therefore be useful and advantageous to express
clostridial neurotoxins as inactive (or less active) single-chain
forms, to eliminate the need for the time-consuming and inefficient
reconstitution of the constituent chains, to maintain solubility of
the protein chains, to reduce protein misfolding and consequent
susceptibility to protease attack, to improve toxin yield, and/or
to provide a simple method for the purification of the toxin.
[0019] Additionally, it would be useful to engineer these toxins to
provide single-chain, modified neurotoxin molecules having novel
therapeutic properties and/or longer duration of action, or toxic
or non-toxic forms for use as transport molecules capable of
delivering a therapeutic moiety to nerve or other cell types. By
expressing such proteins as a single-chain, the yield and
purification of the engineered proteins would be vastly
improved.
SUMMARY OF THE INVENTION
[0020] The present invention is directed to recombinant and
isolated proteins comprising a functional binding domain,
translocation domain, and therapeutic domain in which such proteins
also include an amino acid sequence that is susceptible to specific
cleavage in vitro following expression as a single-chain. Such
proteins may include clostridial neurotoxins and derivatives
thereof, such as those proteins disclosed in Dolly et al., Modified
Clostridial Toxins for Use as Transport Proteins, International
Patent Publication WO 95/32738 (Dec. 7, 1995); and Foster et al.,
Clostridial Toxin Derivatives Able to Modify Peripheral Sensory
Afferent Functions, U.S. Pat. No. 5,989,545 (Nov. 23, 1999), both
incorporated by reference herein.
[0021] In one embodiment of the invention the protein comprises the
functional domains of a clostridial neurotoxin H chain and some or
all of the functions of a clostridial neurotoxin L chain in a
single polypeptide chain, and having an inserted proteolytic
cleavage site located between the H domain and the L domain by
which the single-chain protein may be cleaved to produce the
individual chains, preferably covalently linked by a disulfide
linkage. The invention also includes methods of making such
proteins and expressing them within a cell, as well as nucleic acid
vectors for the transfer and expression of the nucleotide sequence
regions encoding such proteins and cells containing such vectors.
The proteolytic cleavage sites comprise amino acid sequences that
are selectively recognized and cleaved by a specific enzyme.
[0022] In a preferred aspect of the invention, the expressed
single-chain proteins comprise the biologically active domains of
the H chain and L chain of a clostridial neurotoxin. Scission at
the internal proteolytic cleavage site separating the chain domains
thus results in the activation of a neurotoxin having full
activity.
[0023] In another aspect of the invention the single-chain proteins
comprise a binding domain targeted to a cell receptor other than
one borne by a motor neuron. Such a binding domain may specific
bind to, for example, a sensory afferent neuron, or to a
non-neuronal cell type or tissue, such as pancreatic acinar cells.
The single-chain proteins will contain a translocation domain
similar to that of clostridial neurotoxins, and a therapeutic
moiety. The therapeutic moiety may be a clostridial neurotoxin
light chain, or may be a different therapeutic moiety such as an
enzyme, a transcribable nucleotide sequence, growth factor, an
antisense nucleotide sequence and the like.
[0024] Preferably, the toxins and toxin-based proteins of the
present invention will be tailored to contain an additional amino
acid sequence comprising a binding tag able to bind a target
compound at sufficiently high efficiency to facilitate rapid
isolation of the toxin protein. Proteins containing such binding
sites are many and well known to those of skill in the art, and may
comprise, without limitation, monoclonal antibodies, maltose
binding protein, glutathione-S-transferase, protein A, a His.sub.6
tag, and the like.
[0025] Because such proteins exhibit binding selectivity to a
certain compound or compound type, the target compound may be
immobilized to a solid support, including without limitation, a
chromotography resin or microtiter well and used for affinity
purification of the modified toxin. The toxin molecule can then be
eluted by standard methods, such as through the use of a high salt
solution or specific antagonist.
[0026] To minimize the safety risk associated with handling
neurotoxin, the toxins of the this aspect of the present invention
are expressed as their low activity (or inactive) single-chain
proforms, then, by a carefully controlled proteolytic reaction in
vitro, they are activated, preferably to the same potency level as
the native neurotoxin from which they were derived. To improve the
efficiency and rate of proteolytic cleavage the engineered
proteolytic cleavage sites can be designed to occur in a
specially-designed loop between the H and L portions of the single
amino acid chain that promotes accessibility of the protease to the
holotoxin substrate.
[0027] To reduce the risk of unintentional activation of the toxin
by human or commonly encountered proteases, the amino acid
sequences of the cleavage site are preferably designed to have a
high degree of specificity to proteolytic enzymes which do not
normally occur in humans (as either human proteases or occurring in
part of the foreseeable human fauna and flora). A non-exclusive
list of examples of such proteases includes a protease isolated or
derived from a non-human Enterokinase, like bovine enterokinase, a
protease isolated or derived from plant legumain, a protease
isolated or derived from plant papain, such as, e.g., like from
Carica papaya, a protease isolated or derived from insect papain,
like from the silkworm Sitophilus zeamatus, a protease isolated or
derived from crustacian papain, a protease isolated or derived from
Tobacco etch virus (TEV), a protease isolated or derived from a
Tobacco Vein Mottling Virus (TVMV), a protease isolated or derived
from Bacillus amyliquifaciens, such as, e.g., subtilisin and
GENENASE.RTM., a protease isolated or derived from 3c protease from
human rhinovirus (HRV), such as, e.g., PRESCISSION.RTM., a protease
isolated or derived from 3c protease from human enteroviruses
(HEV), and a protease isolated or derived from a non-human Caspase
3.
[0028] In an aspect of the invention the single-chain polypeptide
is an isolated polypeptide. By "isolated" is meant removed from its
natural environment. For example, for a protein expressed within
the cell, isolation includes preparation of a cell lysate as well
as subsequent purification steps. A protein expressed
extracellularly may be isolated by, for example, separation of the
supernatant from the cells as well as any subsequent purification
steps.
[0029] In another aspect of the invention the interchain loop
region of the C. botulinum subtype E neurotoxin, which is normally
resistant to proteolytic nicking in the bacterium and mammals, is
modified to include the inserted proteolytic cleavage site, and
this loop region used as the interchain loop region in the
single-chain toxin or modified toxin molecules of the present
invention. It is believed that using the loop from C. botulinum
subtype E will stabilize the unnicked toxin molecule in vivo,
making it resistant to undesired cleavage until activated through
the use of the selected protease.
[0030] In yet another aspect of the invention compositions are
contemplated comprising recombinant forms of BoNT/E expressed as a
single-chain polypeptide.
[0031] In still another aspect contemplate recombinant chimeric
and/or modified toxin derivatives expressed as a single-chain
polypeptide. Such polypeptide may be molecular transporters, such
as, without limitation, those disclosed in Dolly et al., European
Patent Specification EP 0 760 681 B1, incorporated by reference
herein.
[0032] In a further aspect the invention includes neurotoxin
derivatives comprising at least a portion of a light chain from one
clostridial neurotoxin or subtype thereof, and at least a portion
of a heavy chain from another neurotoxin or neurotoxin subtype, as
well as methods for their production. In one embodiment the hybrid
neurotoxin may contain the entire light chain of a light chain from
one neurotoxin subtype and the heavy chain from another neurotoxin
subtype. In another embodiment, a chimeric neurotoxin derivative
may contain a portion (e.g., the binding domain) of the heavy chain
of one neurotoxin subtype, with another portion of the heavy chain
being from another neurotoxin subtype. Similarly or alternatively,
the therapeutic element may comprise light chain portions from
different neurotoxins.
[0033] Such hybrid or chimeric neurotoxin derivatives are useful,
for example, as a means of delivering the therapeutic benefits of
such neurotoxins to patients who are immunologically resistant to a
given neurotoxin subtype, to patients who may have a lower than
average concentration of receptors to a given neurotoxin heavy
chain binding moiety, or to patients who may have a
protease-resistant variant of the membrane or vesicle toxin
substrate (e.g., SNAP-25, VAMP and syntaxin). Creation of
recombinant chimeric or hybrid neurotoxin derivatives having a
light chain with different substrate would permit such patients to
respond to neurotoxin therapy.
[0034] With regard to immunological resistance, it is known that
most neurotoxin epitopes exist on the heavy chain portion of the
toxin. Thus if a patient has neutralizing antibodies to, for
example BoNT/A, a chimeric neurotoxin containing the heavy chain
from BoNT/E and the light chain from BoNT/A (which has a longer
duration of therapeutic activity than other neurotoxin light
chains) would overcome this resistance. Likewise if the patient has
few cell surface receptors for BoNT/A, the chance are great that
the same patient would have adequate receptors to another BoNT
subtype. By creating a hybrid or chimeric neurotoxin (such as one
containing at least a portion of a heavy chain selected from the
group consisting of HC.sub.A, HC.sub.B, HC.sub.C, HC.sub.D,
HC.sub.E, HC.sub.F, and HC.sub.G and a at least a portion of a
light chain selected from a different clostridial neurotoxin
subtype, said light chain being selected from the group consisting
of LC.sub.A, LC.sub.B, LC.sub.C, LC.sub.D, LC.sub.E, LC.sub.F, and
LC.sub.G) combining the heavy chain of that subtype with the most
therapeutically appropriate light chain (for example, the BoNT/A
light chain) the patient could better respond to neurotoxin
therapy.
[0035] Another advantage of the hybrid or chimeric neurotoxin
derivatives described above is related to the fact that certain of
the light chains (e.g., LC.sub.A) have a long duration of action,
others having a short duration of action (e.g., LC.sub.E and
LC.sub.F) while still others have an intermediate duration of
activity (e.g., LC.sub.B). Thus, hybrid and chimeric neurotoxins
represent second and third generation neurotoxin drugs in which the
neurotoxin activity may be tailored to a specific therapeutic need
or condition, with different drugs having different activities,
substrate specificities or duration of activity.
[0036] Such hybrid or chimeric neurotoxins would also be useful in
treating a patient (such as a soldier or laboratory worker) who has
been inoculated with the pentavalent BoNT vaccine. Such vaccines do
not contain BoNT/F; thus, combining the appropriate light chain
with the BoNT/F heavy chain would create a therapeutic agent which
is effective in such a patient where current therapeutic
neurotoxins may not be.
[0037] The same strategy may be useful in using derivatives of
clostridial neurotoxins with a therapeutic moiety other than an
active neurotoxin light chain. As the heavy chain of such an agent
would be derived from a neurotoxin, it may be advantageous to use a
lesser known, or rarer heavy chain to avoid resistance mechanisms
neutralizing the effectiveness of the therapeutic neurotoxin
derivative.
[0038] By the same token, the binding moiety may be one other than
a binding moiety derived from a clostridial neurotoxin heavy chain,
thus providing a targeting function to cell types other than motor
neurons.
[0039] Also included herein are methods for the construction,
expression, and purification of such molecules in high yield as
biologically active entities.

steps: 1) vesicle docking, where the vesicle-bound SNARE protein of

membrane-bound SNARE proteins located at the plasma membrane; and
2) neurotransmitter release, where the vesicle fuses with the
plasma membrane and the neurotransmitter molecules are exocytosed.
FIG. 18B shows a schematic of the intoxication mechanism for
tetanus and botulinum toxin activity in a central and peripheral
neuron. This intoxication process can be described as comprising
four steps: 1) receptor binding, where a Clostridial toxin binds to
a Clostridial receptor system and initiates the intoxication
process; 2) complex internalization, where after toxin binding, a
vesicle containing the toxin/receptor system complex is endocytosed
into the cell; 3) light chain translocation, where multiple events
are thought to occur, including, e.g., changes in the internal pH
of the vesicle, formation of a channel pore comprising the HN
domain of the Clostridial toxin heavy chain, separation of the
Clostridial toxin light chain from the heavy chain, and release of
the active light chain and 4) enzymatic target modification, where
the activate light chain of Clostridial toxin proteolytically
cleaves its target SNARE substrate, such as, e.g., SNAP-25, VAMP or
Syntaxin, thereby preventing vesicle docking and neurotransmitter
release.
[0062] FIG. 19 shows the domain organization of naturally-occurring
Clostridial toxins. The single-chain form depicts the amino to
carboxyl linear organization comprising an enzymatic domain, a
translocation domain, and a binding domain. The di-chain loop
region located between the translocation and enzymatic domains is
depicted by the double SS bracket. This region comprises an
endogenous di-chain loop protease cleavage site that upon
proteolytic cleavage with a naturally-occurring protease, such as,
e.g., an endogenous Clostridial toxin protease or a
naturally-occurring protease produced in the environment, converts
the single-chain form of the toxin into the di-chain form. Above
the single-chain form, the HCC region of the Clostridial toxin
binding domain is depicted. This region comprises the
.beta.-trefoil domain which comprises in a amino to carboxyl linear

element. Upon proteolytic cleavage with a P protease, the
single-chain form of the toxin is converted to the di-chain form.

DETAILED DESCRIPTION OF THE INVENTION
[0066] Clostridia toxins produced by Clostridium botulinum,
Clostridium tetani, Clostridium baratii and Clostridium butyricum
are the most widely used in therapeutic and cosmetic treatments of
humans and other mammals. Strains of C. botulinum produce seven
antigenically-distinct types of Botulinum toxins (BoNTs), which
have been identified by investigating botulism outbreaks in man
(BoNT/A, /B, /E and /F), animals (BoNT/C1 and /D), or isolated from
soil (BoNT/G). BoNTs possess approximately 35% amino acid identity
with each other and share the same functional domain organization
and overall structural architecture. It is recognized by those of
skill in the art that within each type of Clostridial toxin there
can be subtypes that differ somewhat in their amino acid sequence,
and also in the nucleic acids encoding these proteins. For example,
there are presently four BoNT/A subtypes, BoNT/A1, BoNT/A2, BoNT/A3
and BoNT/A4, with specific subtypes showing approximately 89% amino
acid identity when compared to another BoNT/A subtype. While all
seven BoNT serotypes have similar structure and pharmacological
properties, each also displays heterogeneous bacteriological
characteristics. In contrast, tetanus toxin (TeNT) is produced by a
uniform group of C. tetani. Two other species of Clostridia, C.
baratii and C. butyricum, also produce toxins, BaNT and BuNT
respectively, which are similar to BoNT/F and BoNT/E,
respectively.
[0067] Each mature di-chain molecule comprises three functionally
distinct domains: 1) an enzymatic domain located in the LC that
includes a metalloprotease region containing a zinc-dependent
endopeptidase activity which specifically targets core components
of the neurotransmitter release apparatus; 2) a translocation
domain contained within the amino-terminal half of the HC(H.sub.N)
that facilitates release of the LC from intracellular vesicles into
the cytoplasm of the target cell; and 3) a binding domain found
within the carboxyl-terminal half of the HC (H.sub.C) that
determines the binding activity and binding specificity of the
toxin to the receptor complex located at the surface of the target
cell. The H.sub.C domain comprises two distinct structural features
of roughly equal size that indicate function and are designated the
H.sub.CN and H.sub.CC subdomains. Table 1 gives approximate
boundary regions for each domain found in exemplary Clostridial
toxins.

[0068] The binding, translocation and enzymatic activity of these
three functional domains are all necessary for toxicity. While all
details of this process are not yet precisely known, the overall
cellular intoxication mechanism whereby Clostridial toxins enter a
neuron and inhibit neurotransmitter release is similar, regardless
of serotype or subtype. Although the applicants have no wish to be
limited by the following description, the intoxication mechanism
can be described as comprising at least four steps: 1) receptor
binding, 2) complex internalization, 3) light chain translocation,
and 4) enzymatic target modification (see FIG. 18). The process is
initiated when the H.sub.C domain of a Clostridial toxin binds to a
toxin-specific receptor system located on the plasma membrane
surface of a target cell. The binding specificity of a receptor
complex is thought to be achieved, in part, by specific
combinations of gangliosides and protein receptors that appear to
distinctly comprise each Clostridial toxin receptor complex. Once
bound, the toxin/receptor complexes are internalized by endocytosis
and the internalized vesicles are sorted to specific intracellular
routes. The translocation step appears to be triggered by the
acidification of the vesicle compartment. This process seems to
initiate two important pH-dependent structural rearrangements that
increase hydrophobicity and promote formation di-chain form of the
toxin. Once activated, light chain endopeptidase of the toxin is
released from the intracellular vesicle into the cytosol where it
appears to specifically targets one of three known core components
of the neurotransmitter release apparatus. These core proteins,
vesicle-associated membrane protein (VAMP)/synaptobrevin,
synaptosomal-associated protein of 25 kDa (SNAP-25) and Syntaxin,
are necessary for synaptic vesicle docking and fusion at the nerve
terminal and constitute members of the soluble
N-ethylmaleimide-sensitive factor-attachment protein-receptor
(SNARE) family. BoNT/A and BoNT/E cleave SNAP-25 in the
carboxyl-terminal region, releasing a nine or twenty-six amino acid
segment, respectively, and BoNT/C1 also cleaves SNAP-25 near the
carboxyl-terminus. The botulinum serotypes BoNT/B, BoNT/D, BoNT/F
and BoNT/G, and tetanus toxin, act on the conserved central portion
of VAMP, and release the amino-terminal portion of VAMP into the
cytosol. BoNT/C1 cleaves syntaxin at a single site near the
cytosolic membrane surface. The selective proteolysis of synaptic
SNAREs accounts for the block of neurotransmitter release caused by
Clostridial toxins in vivo. The SNARE protein targets of
Clostridial toxins are common to exocytosis in a variety of
non-neuronal types; in these cells, as in neurons, light chain
peptidase activity inhibits exocytosis, see, e.g., Yann Humeau et
al., How Botulinum and Tetanus Neurotoxins Block Neurotransmitter
Release, 82(5) Biochimie. 427-446 (2000); Kathryn Turton et al.,

Therapeutic Utility, 27(11) Trends Biochem. Sci. 552-558. (2002);
Giovanna Lalli et al., The Journey of Tetanus and Botulinum
Neurotoxins in Neurons, 11 (9) Trends Microbiol. 431-437,
(2003).
[0069] Clostridial toxins are each translated as a single-chain
polypeptide of approximately 150 kDa that is subsequently cleaved
by proteolytic scission within a disulfide loop by a
naturally-occurring protease (FIG. 18). This cleavage occurs within
the discrete di-chain loop region created between two cysteine
residues that form a disulfide bridge. This posttranslational
processing yields a di-chain molecule comprising an approximately
50 kDa light chain (LC) and an approximately 100 kDa heavy chain
(HC) held together by the single disulfide bond and non-covalent
interactions between the two chains. The naturally-occurring
protease used to convert the single-chain molecule into the
di-chain is currently not known. In some bacterial serotypes, such
as, e.g., a BoNT/A, a BoNT/B proteolytic, a BoNT/F proteolytic, a
BaNT proteolytic strain, or a TeNT, the naturally-occurring
protease is produced endogenously by the bacteria serotype and
cleavage occurs within the cell before the toxin is release into
the environment. However, in other bacterial serotypes, such as,
e.g., a BoNT/B nonproteolytic, a BoNT/C1, a BoNT/D, a BoNT/E, a
BoNT/F nonproteolytic, a BoNT/G, a BaNT nonproteolytic, or a BuNT,
the bacterial strain appears not to produce appreciable amounts of
an endogenous protease capable of converting the single-chain form
of the toxin into the di-chain form. In these situations, the toxin
is released from the cell as a single-chain toxin which is
subsequently converted into the di-chain form by a
naturally-occurring protease found in the environment.
[0070] The compositions and methods of the present invention
involve modified neurotoxins, their synthesis and use. Di-chain
neurotoxins that are normally activated by scission of a
single-chain polypeptide by indigenous proteases can be modified at
the nucleic acid level by alteration or removal of the nucleotide
sequence encoding the indigenous protease cleavage site and
insertion of a nucleotide sequence encoding another different
proteolytic cleavage site resistant to cleavage by host cell or
human proteases. The inserted amino acid sequence is designed to be
cleaved in vitro through the use of a cleaving agent chosen in
advance of expression that is, absent from both human and host cell
tissue.
[0071] The amino acid sequences recognized by many proteases, and
their cleavage specificity are well-known to those of skill in the
art. Thus, both the design of a specific proteolytic cleavage site
in the loop region between the L and H chain portions of the
single-chain toxin and the modification of incidental protease
sites in the polypeptide to be protease-resistant is a routine
matter of comparing the specificity and recognition sequences for
various proteins. In the first case, the specificity of a candidate
proteolytic site need not be totally exclusive, but merely needs to
exclude cleavage sites for human and/or host cell proteases that
might be present during the handling, storage and purification of
the single-chain neurotoxin. Of course, it is preferable that the
protease site is as specific as possible. In the latter case, the
modification of the proteolytic cleavage site need only be
sufficient to render the site resistant to the activator protease
and to human and host cell proteases.
[0072] As mentioned above, a Clostridial toxin is converted from a
single polypeptide form into a di-chain molecule by proteolytic
cleavage. While the naturally-occurring protease is currently not
known, cleavage occurs within the di-chain loop region between the
two cysteine residues that form the disulfide bridge (Table 2). As
used herein, the term "di-chain loop region" means the amino acid
sequence of a Clostridial toxin containing a protease cleavage site
used to convert the single-chain polypeptide form of a Clostridial
toxin into the di-chain form. Non-limiting examples of a
Clostridial toxin di-chain loop region, include, a di-chain loop
region of BoNT/A comprising SEQ ID NO: 11; a di-chain loop region
of BoNT/B comprising SEQ ID NO: 12; a di-chain loop region of

comprising SEQ ID NO: 15; a di-chain loop region of BoNT/F
comprising SEQ ID NO: 16; a di-chain loop region of BoNT/G

SEQ ID NO: 18, a di-chain loop region of BaNT comprising SEQ ID NO:
19, and a di-chain loop region of BuNT comprising SEQ ID NO: 20
(Table 2).

indicates the peptide bond of the P.sub.1-P.sub.1 cleavage site
that is believed to be cleaved by a Clostridial toxin di-chain loop
protease.
[0073] The inserted amino acid sequence may be chosen to confer
susceptibility to a chemical agent capable of cleaving peptide
bonds, such as cyanogen bromide. However, and much more preferably,
the encoded amino acid sequence may comprise a proteolytic cleavage
site highly specific for a selected protease. The selected protease
may be any protease that recognizes a specific amino acid sequence
and cleaves a peptide bond near or at that location, but the
selected protease is very preferably not a human protease such as,
e.g., human trypsin, chymotrypsin or pepsin, or a protease
expressed in the host cell. Moreover, the selected protease does
not recognize the same amino acid sequence as the endogenous
protease (i.e., the naturally-occurring di-chain loop protease
cleavage site). Finally, the selected protease should not be one
expressed by the host cell that contains the plasmid encoding the
recombinant neurotoxin. Any non-human protease recognizing a
relatively rare amino acid sequence may be used, provided that the
amino acid recognition sequence is also known. Examples of
proteases to be selected as activators may include any of the
following, without limitation: a protease isolated or derived from
non-human Enterokinase, such as, e.g., a bovine enterokinase, a
protease isolated or derived from plant legumain, a protease
isolated or derived from plant papain, such as, e.g., like from
Carica papaya, a protease isolated or derived from insect papain,
like from the silkworm Sitophilus zeamatus, a protease isolated or
derived from crustacian papain, a protease isolated or derived from
Tobacco etch virus (TEV), a protease isolated or derived from a
Tobacco Vein Mottling Virus (TVMV), a protease isolated or derived
from Bacillus amyliquifaciens, such as, e.g., subtilisin and
GENENASE.RTM., a protease isolated or derived from 3c protease from
human rhinovirus (HRV), such as, e.g., PRESCISSION.RTM., a protease
isolated or derived from 3c protease from human enteroviruses (HEV)
and a protease isolated or derived from a non-human Caspase 3, such
as, e.g., a mouse Caspase 3.
[0074] In another aspect of the invention, a modified Clostridial
toxin comprises, in part, an exogenous protease cleavage site
within a di-chain loop region. As used herein, the term "exogenous
protease cleavage site" is synonymous with a "non-naturally
occurring protease cleavage site" or "non-native protease cleavage
site" and means a protease cleavage site that is not normally
present in a di-chain loop region from a naturally occurring
Clostridial toxin, with the proviso that the exogenous protease
cleavage site is not a human protease cleavage site or a protease
cleavage site that is susceptible to a protease being expressed in
the host cell that is expressing a construct encoding an

any amino acid. In other aspects of the embodiment, an exogenous
protease cleavage site can comprise, e.g., a SUMO/ULP-1 protease
cleavage site located within the di-chain loop of a modified
Clostridial toxin comprises SEQ ID NO: 56. In still other aspects
of this embodiment, a SUMO/ULP-1 protease cleavage site is located
within the di-chain loop of, e.g., a modified BoNT/A, a modified

[0084] In an aspect of this embodiment, an exogenous protease
cleavage site can comprise, e.g., a non-human Caspase 3 cleavage
site is located within the di-chain loop of a modified Clostridial

modified BoNT/G, a modified TeNT, a modified BaNT, or a modified
BuNT.
[0085] A di-chain loop region is modified to replace a
naturally-occurring di-chain loop protease cleavage site for an
exogenous protease cleavage site. In this modification, the
naturally-occurring di-chain loop protease cleavage site is made
inoperable and thus can not be cleaved by its protease. Only the
exogenous protease cleavage site can be cleaved by its
corresponding exogenous protease. In this type of modification, the
exogenous protease site is operably-linked in-frame to a modified
Clostridial toxin as a fusion protein and the site can be cleaved
by its respective exogenous protease. Replacement of an endogenous
di-chain loop protease cleavage site with an exogenous protease
cleavage site can be a substitution of the sites where the
exogenous site is engineered at the position approximating the
cleavage site location of the endogenous site. Replacement of an
endogenous di-chain loop protease cleavage site with an exogenous
protease cleavage site can be an addition of an exogenous site
where the exogenous site is engineered at the position different
from the cleavage site location of the endogenous site, the
endogenous site being engineered to be inoperable. The location and
kind of protease cleavage site may be critical because certain
binding domains require a free amino-terminal or carboxyl-terminal
amino acid. For example, when a binding domain is placed between
two other domains, e.g., see FIG. 22, a criterion for selection of
a protease cleavage site could be whether the protease that cleaves
its site leaves a flush cut, exposing the free amino-terminal or
carboxyl-terminal of the binding domain necessary for selective
binding of the binding domain to its receptor.
[0086] A naturally-occurring protease cleavage site can be made
inoperable by altering at least the two amino acids flanking the
peptide bond cleaved by the naturally-occurring di-chain loop
protease. More extensive alterations can be made, with the proviso
that the two cysteine residues of the di-chain loop region remain
intact and the region can still form the disulfide bridge.
Non-limiting examples of an amino acid alteration include deletion
of an amino acid or replacement of the original amino acid with a
different amino acid. Thus, in one embodiment, a
naturally-occurring protease cleavage site is made inoperable by
altering the two amino acids flanking the peptide bond cleaved by a
naturally-occurring protease. In other aspects of this embodiment,
a naturally-occurring protease cleavage site is made inoperable by
altering, e.g., at least three amino acids including the two amino
acids flanking the peptide bond cleaved by a naturally-occurring
protease; at least four amino acids including the two amino acids
flanking the peptide bond cleaved by a naturally-occurring
protease; at least five amino acids including the two amino acids
flanking the peptide bond cleaved by a naturally-occurring
protease; at least six amino acids including the two amino acids
flanking the peptide bond cleaved by a naturally-occurring
protease; at least seven amino acids including the two amino acids
flanking the peptide bond cleaved by a naturally-occurring
protease; at least eight amino acids including the two amino acids
flanking the peptide bond cleaved by a naturally-occurring
protease; at least nine amino acids including the two amino acids
flanking the peptide bond cleaved by a naturally-occurring
protease; at least ten amino acids including the two amino acids
flanking the peptide bond cleaved by a naturally-occurring
protease; at least 15 amino acids including the two amino acids
flanking the peptide bond cleaved by a naturally-occurring
protease; or at least 20 amino acids including the two amino acids
flanking the peptide bond cleaved by a naturally-occurring
protease.
[0087] In still other aspects of this embodiment, a
naturally-occurring di-chain protease cleavage site is made
inoperable by altering, e.g., at most three amino acids including
the two amino acids flanking the peptide bond cleaved by a
naturally-occurring protease; at most four amino acids including
the two amino acids flanking the peptide bond cleaved by a
naturally-occurring protease; at most five amino acids including
the two amino acids flanking the peptide bond cleaved by a
naturally-occurring protease; at most six amino acids including the
two amino acids flanking the peptide bond cleaved by a
naturally-occurring protease; at most seven amino acids including
the two amino acids flanking the peptide bond cleaved by a
naturally-occurring protease; at most eight amino acids including
the two amino acids flanking the peptide bond cleaved by a
naturally-occurring protease; at most nine amino acids including
the two amino acids flanking the peptide bond cleaved by a
naturally-occurring protease; at most ten amino acids including the
two amino acids flanking the peptide bond cleaved by a
naturally-occurring protease; at most 15 amino acids including the
two amino acids flanking the peptide bond cleaved by a
naturally-occurring protease; or at most 20 amino acids including
the two amino acids flanking the peptide bond cleaved by a
naturally-occurring protease.
[0088] It is understood that a modified Clostridial toxin disclosed
in the present specification can optionally further comprise a
flexible region comprising a flexible spacer. Non-limiting examples
of a flexible spacer include, e.g., a G-spacer GGGGS (SEQ ID NO:
64) or an A-spacer EAAAK (SEQ ID NO: 65). A flexible region
comprising flexible spacers can be used to adjust the length of a
polypeptide region in order to optimize a characteristic, attribute
or property of a polypeptide. Such a flexible region is
operably-linked in-frame to the modified Clostridial toxin as a
fusion protein. As a non-limiting example, a polypeptide region
comprising one or more flexible spacers in tandem can be use to
better expose a protease cleavage site thereby facilitating
cleavage of that site by a protease. As another non-limiting
example, a polypeptide region comprising one or more flexible
spacers in tandem can be use to better present a binding domain,
thereby facilitating the binding of that binding domain to its
receptor.
[0089] Thus, in an embodiment, a modified Clostridial toxin
disclosed in the present specification can further comprise a
flexible region comprising a flexible spacer. In another
embodiment, a modified Clostridial toxin disclosed in the present
specification can further comprise flexible region comprising a
plurality of flexible spacers in tandem. In aspects of this
embodiment, a flexible region can comprise in tandem, e.g., at
least 1 G-spacer, at least 2 G-spacers, at least 3 G-spacers, at
least 4 G-spacers or at least 5 G-spacers. In other aspects of this
embodiment, a flexible region can comprise in tandem, e.g., at most
1 G-spacer, at most 2 G-spacers, at most 3 G-spacers, at most 4
G-spacers or at most 5 G-spacers. In still other aspects of this
embodiment, a flexible region can comprise in tandem, e.g., at
least 1 A-spacer, at least 2 A-spacers, at least 3 A-spacers, at
least 4 A-spacers or at least 5 A-spacers. In still other aspects
of this embodiment, a flexible region can comprise in tandem, e.g.,
at most 1 A-spacer, at most 2 A-spacers, at most 3 A-spacers, at
most 4 A-spacers or at most 5 A-spacers. In another aspect of this
embodiment, a modified Clostridial toxin can comprise a flexible
region comprising one or more copies of the same flexible spacers,
one or more copies of different flexible-spacer regions, or any
combination thereof.
[0090] In other aspects of this embodiment, a modified Clostridial
toxin comprising a flexible spacer can be, e.g., a modified BoNT/A,
a modified BoNT/B, a modified BoNT/C1, a modified BoNT/D, a
modified BoNT/E, a modified BoNT/F, a modified BoNT/G, a modified
TeNT, a modified BaNT, or a modified BuNT.
[0091] It is envisioned that a modified Clostridial toxin disclosed
in the present specification can comprise a flexible spacer in any
and all locations with the proviso that modified Clostridial toxin
is capable of performing the intoxication process. In aspects of
this embodiment, a flexible spacer is positioned between, e.g., a
therapeutic element and a translocation element, a therapeutic
element and a binding element, a therapeutic element and an
exogenous protease cleavage site. In other aspects of this
embodiment, a G-spacer is positioned between, e.g., a therapeutic
element and a translocation element, a therapeutic element and a
binding element, a therapeutic element and an exogenous protease
cleavage site. In other aspects of this embodiment, an A-spacer is
positioned between, e.g., a therapeutic element and a translocation
element, a therapeutic element and a binding element, a therapeutic
element and an exogenous protease cleavage site.
[0092] In other aspects of this embodiment, a flexible spacer is
positioned between, e.g., a binding element and a translocation
element, a binding element and a therapeutic element, a binding
element and an exogenous protease cleavage site. In other aspects
of this embodiment, a G-spacer is positioned between, e.g., a
binding element and a translocation element, a binding element and
a therapeutic element, a binding element and an exogenous protease
cleavage site. In other aspects of this embodiment, an A-spacer is
positioned between, e.g., a binding element and a translocation
element, a binding element and a therapeutic element, a binding
element and an exogenous protease cleavage site.
[0093] In yet other aspects of this embodiment, a flexible spacer
is positioned between, e.g., a translocation element and a
therapeutic element, a translocation element and a binding element,
a translocation element and an exogenous protease cleavage site. In
other aspects of this embodiment, a G-spacer is positioned between,
e.g., a translocation element and a therapeutic element, a
translocation element and a binding element, a translocation
element and an exogenous protease cleavage site. In other aspects
of this embodiment, an A-spacer is positioned between, e.g., a
translocation element and a therapeutic element, a translocation
element and a binding element, a translocation element and an
exogenous protease cleavage site.
[0094] In another aspect, the invention is drawn to recombinant
single-chain modified clostridial neurotoxins that may be cleaved
at will by a protease to provide an active di-chain molecule. Such
modified neurotoxins need not be toxic; in certain of these
proteins the enzymatic activity of the toxin L chain may be
abrogated, and the toxin joined to a drug or other bioactive agent
having therapeutic activity. Alternatively, in certain other
modified neurotoxins the L chain is enzymatically active, but
portions of the H chain are modified to provide specificity to
target cells other than the natural target of the neurotoxin, while
maintaining the translocation and endocytosis-stimulating
activities of the native toxin. Modified neurotoxins such as those
described in this aspect of the invention are disclosed in, for
example, Dolly et al., Modified Clostridial Toxins for Use as
Transport Proteins, International Patent Publication WO 95/32738

publications are incorporated by reference herein. The present
invention provides single-chain, cleavable versions of these
molecules and improved methods of making such molecules.
[0095] In another aspect, the invention comprises a modified
clostridial neurotoxin derived from tetanus toxin (TeNT), or one or
more of the botulinum toxin (BONT) subtypes in which the
naturally-occurring interchain loop region has been replace with a
modified loop region comprising a different amino acid sequence
conferring 1) resistance to cleavage by host proteases or autolytic
action, and/or 2) lability to a selected protease. Preferably the
cleavage site is highly specific for the selected protease. The
interchain loop region of certain clostridial neurotoxins, for
example, BoNT/E, is naturally resistant to proteolytic cleavage in
vivo. This protease resistance may reflect a secondary or tertiary
structure that makes the loop more resistant to indigenous
proteases than other clostridial neurotoxins. In one embodiment of
the present invention, therefore, the inter-chain loop region of
BoNT/E is substituted for the natural loop region occurring an
another BoNT having greater therapeutic activity or duration of
action, for example BoNT/A or /B. In another embodiment of the
invention the loop region of BoNT/E is modified to contain a
proteolytic cleavage site highly specific to a selected protease
prior to the subcloning. The otherwise highly conserved BoNT/E loop
region would be resistant to indigenous proteases, or those
encountered within a human, but would retain the ability to be
activated by digestion with the selected protease.
[0096] Unless indicated otherwise, the following terms have the
following meanings in this specification:
[0097] The "therapeutic element" of the present invention may
comprise, without limitation: active or inactive (i.e., modified)
hormone receptors (such as androgen, estrogen, retinoid,
perioxysome proliferator and ecdysone receptors etc.), and
hormone-agonists and antagonists, nucleic acids capable being of
being used as replication, transcription, or translational
templates (e.g., for expression of a protein drug having the
desired biological activity or for synthesis of a nucleic acid drug
as an antisense agent), enzymes, toxins (including
apoptosis-inducing or -preventing agents), and the like.
[0098] In a preferred embodiment, the therapeutic element is a
polypeptide comprising a clostridial neurotoxin light chain or a
portion thereof retaining the SNARE-protein sequence-specific
endopeptidase activity of a clostridial neurotoxin light chain. The
amino acid sequences of the light chain of botulinum neurotoxin
(BONT) subtypes A-G have been determined, as has the amino acid
sequence of the light chains of the tetanus neurotoxin (TeNT),
Baratii neurotoxin (BaNT), and butyricum neurotoxin (BuNT). Each
chain contains the Zn.sup.++-binding motif His-Glu-Xaa-Xaa-His (SEQ
ID NO: 66).
[0099] Recent studies of the BoNT/A light chain have revealed
certain features important for the activity and specificity of the
toxin towards its target substrate, SNAP-25. Thus, studies by Zhou
et al. Biochemistry 34:15175-15181 (1995) have indicated that when
the light chain amino acid residue His.sub.227 is substituted with
tyrosine, the resulting polypeptide is unable to cleave SNAP-25;
Kurazono et al., J. Biol. Chem. 14721-14729 (1992) performed
studies in the presynaptic cholinergic neurons of the buccal
ganglia of Aplysia californica using recombinant BoNT/A light chain
that indicated that the removal of 8 N-terminal or 32 C-terminal
residues did not abolish toxicity, but that removal of 10
N-terminal or 57 C-terminal residues abolished toxicity in this
system. Most recently, the crystal structure of the entire BoNT/A
holotoxin has been solved; the active site is indicated as
involving the participation of His.sub.222, Glu.sub.223,
His.sub.226, Glu.sub.26, and Tyr.sub.365. Lacy et al., supra.
(These residues correspond to His.sub.223, Glu.sub.224,
His.sub.227, Glu.sub.262 and Tyr.sub.366 of the BoNT/A L chain of
Kurazono et al., supra.) Interestingly, an alignment of BoNT/A
through E and TeNT light chains reveals that every such chain
invariably has these residues in positions analogous to BoNT/A.
Kurazono et al., supra.
[0100] The catalytic domain of BoNT/A is very specific for the
C-terminus of SNAP-25 and appears to require a minimum of 17
SNAP-25 amino acids for cleavage to occur. The catalytic site
resembles a pocket; when the light chained is linked to the heavy
chain via the disulfide bond between Cys.sub.429 and Cys.sub.453,
the translocation domain of the heavy chain appears to block access
to the catalytic pocket until the light chain gains entry to the
cytosol. When the disulfide bond is then reduced, the catalytic
pocket is "opened" and the light chain is fully active.
[0101] The substrate specificities of the various clostridial
neurotoxin light chains other than BoNT/A are known. As described
above, VAMP and syntaxin are cleaved by BoNT/B, D, F, G and TeNT,
and BoNT/C.sub.1, respectively, while SNAP-25 is cleaved by BoNT/A
E and C1. Therefore, the person of ordinary skill in the art could
easily determine the toxin residues essential in these subtypes for
cleavage and substrate recognition (for example, by site-directed
mutagenesis or deletion of various regions of the toxin molecule
followed by testing of proteolytic activity and substrate
specificity), and could therefore easily design variants of the
native neurotoxin light chain that retain or lack the same or
similar activity.
[0102] Aspects of the present invention provide, in part, a
Clostridial toxin enzymatic domain. As used herein, the term
"Clostridial toxin enzymatic domain" means any Clostridial toxin
polypeptide that can execute the enzymatic target modification step
of the intoxication process. Thus, a Clostridial toxin enzymatic
domain specifically targets a Clostridial toxin substrate and
encompasses the proteolytic cleavage of a Clostridial toxin
substrate, such as, e.g., SNARE proteins like a SNAP-25 substrate,
a VAMP substrate and a Syntaxin substrate. Non-limiting examples of
a Clostridial toxin enzymatic domain include, e.g., a BoNT/A
enzymatic domain, a BoNT/B enzymatic domain, a BoNT/C1 enzymatic
domain, a BoNT/D enzymatic domain, a BoNT/E enzymatic domain, a
BoNT/F enzymatic domain, a BoNT/G enzymatic domain, a TeNT
enzymatic domain, a BaNT enzymatic domain, and a BuNT enzymatic
domain. Other non-limiting examples of a Clostridial toxin
enzymatic domain include, e.g., amino acids 1-448 of SEQ ID NO: 1,
amino acids 1-441 of SEQ ID NO: 2, amino acids 1-449 of SEQ ID NO:
3, amino acids 1-445 of SEQ ID NO: 4, amino acids 1-422 of SEQ ID
NO: 5, amino acids 1-439 of SEQ ID NO: 6, amino acids 1-446 of SEQ
ID NO: 7, amino acids 1-457 of SEQ ID NO: 8, amino acids 1-431 of
SEQ ID NO: 9, and amino acids 1-422 of SEQ ID NO: 10.
[0103] A Clostridial toxin enzymatic domain includes, without
limitation, naturally occurring Clostridial toxin enzymatic domain
variants, such as, e.g., Clostridial toxin enzymatic domain
isoforms and Clostridial toxin enzymatic domain subtypes;
non-naturally occurring Clostridial toxin enzymatic domain
variants, such as, e.g., conservative Clostridial toxin enzymatic
domain variants, non-conservative Clostridial toxin enzymatic
domain variants, Clostridial toxin enzymatic domain chimerics,
active Clostridial toxin enzymatic domain fragments thereof, or any
combination thereof.
[0104] As used herein, the term "Clostridial toxin enzymatic domain
variant," whether naturally-occurring or non-naturally-occurring,
means a Clostridial toxin enzymatic domain that has at least one
amino acid change from the corresponding region of the disclosed
reference sequences (Table 1) and can be described in percent
identity to the corresponding region of that reference sequence.
Unless expressly indicated, all Clostridial toxin enzymatic domain
variants disclosed in the present specification are capable of
executing the enzymatic target modification step of the
intoxication process. As non-limiting examples, a BoNT/A enzymatic
domain variant comprising amino acids 1-448 of SEQ ID NO: 1 will
have at least one amino acid difference, such as, e.g., an amino
acid substitution, deletion or addition, as compared to the amino
acid region 1-448 of SEQ ID NO: 1; a BoNT/B enzymatic domain
variant comprising amino acids 1-441 of SEQ ID NO: 2 will have at
least one amino acid difference, such as, e.g., an amino acid
substitution, deletion or addition, as compared to the amino acid
region 1-441 of SEQ ID NO: 2; a BoNT/C1 enzymatic domain variant
comprising amino acids 1-449 of SEQ ID NO: 3 will have at least one
amino acid difference, such as, e.g., an amino acid substitution,
deletion or addition, as compared to the amino acid region 1-449 of
SEQ ID NO: 3; a BoNT/D enzymatic domain variant comprising amino
acids 1-445 of SEQ ID NO: 4 will have at least one amino acid
difference, such as, e.g., an amino acid substitution, deletion or
addition, as compared to the amino acid region 1-445 of SEQ ID NO:
4; a BoNT/E enzymatic domain variant comprising amino acids 1-422
of SEQ ID NO: 5 will have at least one amino acid difference, such
as, e.g., an amino acid substitution, deletion or addition, as
compared to the amino acid region 1-422 of SEQ ID NO: 5; a BoNT/F
enzymatic domain variant comprising amino acids 1-439 of SEQ ID NO:
6 will have at least one amino acid difference, such as, e.g., an
amino acid substitution, deletion or addition, as compared to the
amino acid region 1-439 of SEQ ID NO: 6; a BoNT/G enzymatic domain
variant comprising amino acids 1-446 of SEQ ID NO: 7 will have at
least one amino acid difference, such as, e.g., an amino acid
substitution, deletion or addition, as compared to the amino acid
region 1-446 of SEQ ID NO: 7; and a TeNT enzymatic domain variant
comprising amino acids 1-457 of SEQ ID NO: 8 will have at least one
amino acid difference, such as, e.g., an amino acid substitution,
deletion or addition, as compared to the amino acid region 1-457 of
SEQ ID NO: 8.
[0105] It is recognized by those of skill in the art that within
each serotype of Clostridial toxin there can be naturally occurring
Clostridial toxin enzymatic domain variants that differ somewhat in
their amino acid sequence, and also in the nucleic acids encoding
these proteins. For example, there are presently four BoNT/A
subtypes, BoNT/A1, BoNT/A2, BoNT/A3 and BoNT/A4, with specific
enzymatic domain subtypes showing approximately 95% amino acid
identity when compared to another BoNT/A enzymatic domain subtype.
As used herein, the term "naturally occurring Clostridial toxin
enzymatic domain variant" means any Clostridial toxin enzymatic
domain produced by a naturally-occurring process, including,
without limitation, Clostridial toxin enzymatic domain isoforms
produced from alternatively-spliced transcripts, Clostridial toxin
enzymatic domain isoforms produced by spontaneous mutation and
Clostridial toxin enzymatic domain subtypes. A naturally occurring
Clostridial toxin enzymatic domain variant can function in
substantially the same manner as the reference Clostridial toxin
enzymatic domain on which the naturally occurring Clostridial toxin
enzymatic domain variant is based, and can be substituted for the
reference Clostridial toxin enzymatic domain in any aspect of the
present invention. A naturally occurring Clostridial toxin
enzymatic domain variant may substitute one or more amino acids,
two or more amino acids, three or more amino acids, four or more
amino acids, five or more amino acids, ten or more amino acids, 20
or more amino acids, 30 or more amino acids, 40 or more amino
acids, 50 or more amino acids or 100 or more amino acids from the
reference Clostridial toxin enzymatic domain on which the naturally
occurring Clostridial toxin enzymatic domain variant is based. A
naturally occurring Clostridial toxin enzymatic domain variant can
also substitute at least 10 contiguous amino acids, at least 15
contiguous amino acids, at least 20 contiguous amino acids, or at
least 25 contiguous amino acids from the reference Clostridial
toxin enzymatic domain on which the naturally occurring Clostridial
toxin enzymatic domain variant is based, that possess at least 50%
amino acid identity, 65% amino acid identity, 75% amino acid
identity, 85% amino acid identity or 95% amino acid identity to the
reference Clostridial toxin enzymatic domain on which the naturally
occurring Clostridial toxin enzymatic domain variant is based.
[0106] A non-limiting examples of a naturally occurring Clostridial
toxin enzymatic domain variant is a Clostridial toxin enzymatic
domain isoform such as, e.g., a BoNT/A enzymatic domain isoform, a
BoNT/B enzymatic domain isoform, a BoNT/C1 enzymatic domain
isoform, a BoNT/D enzymatic domain isoform, a BoNT/E enzymatic
domain isoform, a BoNT/F enzymatic domain isoform, a BoNT/G
enzymatic domain isoform, and a TeNT enzymatic domain isoform. A
Clostridial toxin enzymatic domain isoform can function in
substantially the same manner as the reference Clostridial toxin
enzymatic domain on which the Clostridial toxin enzymatic domain
isoform is based, and can be substituted for the reference
Clostridial toxin enzymatic domain in any aspect of the present
invention.
[0107] Another non-limiting examples of a naturally occurring
Clostridial toxin enzymatic domain variant is a Clostridial toxin
enzymatic domain subtype such as, e.g., a enzymatic domain from
subtype BoNT/A1, BoNT/A2, BoNT/A3 and BoNT/A4; a enzymatic domain
from subtype BoNT/B1, BoNT/B2, BoNT/B bivalent and BoNT/B
nonproteolytic; a enzymatic domain from subtype BoNT/C1-1 and
BoNT/C1-2; a enzymatic domain from subtype BoNT/E1, BoNT/E2 and
BoNT/E3; and a enzymatic domain from subtype BoNT/F1, BoNT/F2,
BoNT/F3 and BoNT/F4. A Clostridial toxin enzymatic domain subtype
can function in substantially the same manner as the reference
Clostridial toxin enzymatic domain on which the Clostridial toxin
enzymatic domain subtype is based, and can be substituted for the
reference Clostridial toxin enzymatic domain in any aspect of the
present invention.
[0108] As used herein, the term "non-naturally occurring
Clostridial toxin enzymatic domain variant" means any Clostridial
toxin enzymatic domain produced with the aid of human manipulation,
including, without limitation, Clostridial toxin enzymatic domains
produced by genetic engineering using random mutagenesis or
rational design and Clostridial toxin enzymatic domains produced by
chemical synthesis. Non-limiting examples of non-naturally
occurring Clostridial toxin enzymatic domain variants include,
e.g., conservative Clostridial toxin enzymatic domain variants,
non-conservative Clostridial toxin enzymatic domain variants,
Clostridial toxin enzymatic domain chimeric variants and active
Clostridial toxin enzymatic domain fragments.
[0109] As used herein, the term "conservative Clostridial toxin
enzymatic domain variant" means a Clostridial toxin enzymatic
domain that has at least one amino acid substituted by another
amino acid or an amino acid analog that has at least one property
similar to that of the original amino acid from the reference
Clostridial toxin enzymatic domain sequence (Table 1). Examples of
properties include, without limitation, similar size, topography,
charge, hydrophobicity, hydrophilicity, lipophilicity,
covalent-bonding capacity, hydrogen-bonding capacity, a
physicochemical property, of the like, or any combination thereof.
A conservative Clostridial toxin enzymatic domain variant can
function in substantially the same manner as the reference
Clostridial toxin enzymatic domain on which the conservative
Clostridial toxin enzymatic domain variant is based, and can be
substituted for the reference Clostridial toxin enzymatic domain in
any aspect of the present invention. A conservative Clostridial
toxin enzymatic domain variant may substitute one or more amino
acids, two or more amino acids, three or more amino acids, four or
more amino acids, five or more amino acids, ten or more amino
acids, 20 or more amino acids, 30 or more amino acids, 40 or more
amino acids, 50 or more amino acids, 100 or more amino acids, 200
or more amino acids, 300 or more amino acids, 400 or more amino
acids, or 500 or more amino acids from the reference Clostridial
toxin enzymatic domain on which the conservative Clostridial toxin
enzymatic domain variant is based. A conservative Clostridial toxin
enzymatic domain variant can also substitute at least 10 contiguous
amino acids, at least 15 contiguous amino acids, at least 20
contiguous amino acids, or at least 25 contiguous amino acids from
the reference Clostridial toxin enzymatic domain on which the
conservative Clostridial toxin enzymatic domain variant is based,
that possess at least 50% amino acid identity, 65% amino acid
identity, 75% amino acid identity, 85% amino acid identity or 95%
amino acid identity to the reference Clostridial toxin enzymatic
domain on which the conservative Clostridial toxin enzymatic domain
variant is based. Non-limiting examples of a conservative
Clostridial toxin enzymatic domain variant include, e.g.,
conservative BoNT/A enzymatic domain variants, conservative BoNT/B
enzymatic domain variants, conservative BoNT/C1 enzymatic domain
variants, conservative BoNT/D enzymatic domain variants,
conservative BoNT/E enzymatic domain variants, conservative BoNT/F
enzymatic domain variants, conservative BoNT/G enzymatic domain
variants, and conservative TeNT enzymatic domain variants.
[0110] As used herein, the term "non-conservative Clostridial toxin
enzymatic domain variant" means a Clostridial toxin enzymatic
domain in which 1) at least one amino acid is deleted from the
reference Clostridial toxin enzymatic domain on which the
non-conservative Clostridial toxin enzymatic domain variant is
based; 2) at least one amino acid added to the reference
Clostridial toxin enzymatic domain on which the non-conservative
Clostridial toxin enzymatic domain is based; or 3) at least one
amino acid is substituted by another amino acid or an amino acid
analog that does not share any property similar to that of the
original amino acid from the reference Clostridial toxin enzymatic
domain sequence (Table 1). A non-conservative Clostridial toxin
enzymatic domain variant can function in substantially the same
manner as the reference Clostridial toxin enzymatic domain on which
the non-conservative Clostridial toxin enzymatic domain variant is
based, and can be substituted for the reference Clostridial toxin
enzymatic domain in any aspect of the present invention. A
non-conservative Clostridial toxin enzymatic domain variant can
delete one or more amino acids, two or more amino acids, three or
more amino acids, four or more amino acids, five or more amino
acids, and ten or more amino acids from the reference Clostridial
toxin enzymatic domain on which the non-conservative Clostridial
toxin enzymatic domain variant is based. A non-conservative
Clostridial toxin enzymatic domain variant can add one or more
amino acids, two or more amino acids, three or more amino acids,
four or more amino acids, five or more amino acids, and ten or more
amino acids to the reference Clostridial toxin enzymatic domain on
which the non-conservative Clostridial toxin enzymatic domain
variant is based. A non-conservative Clostridial toxin enzymatic
domain variant may substitute one or more amino acids, two or more
amino acids, three or more amino acids, four or more amino acids,
five or more amino acids, ten or more amino acids, 20 or more amino
acids, 30 or more amino acids, 40 or more amino acids, 50 or more
amino acids, 100 or more amino acids, 200 or more amino acids, 300
or more amino acids, 400 or more amino acids, or 500 or more amino
acids from the reference Clostridial toxin enzymatic domain on
which the non-conservative Clostridial toxin enzymatic domain
variant is based. A non-conservative Clostridial toxin enzymatic
domain variant can also substitute at least 10 contiguous amino
acids, at least 15 contiguous amino acids, at least 20 contiguous
amino acids, or at least 25 contiguous amino acids from the
reference Clostridial toxin enzymatic domain on which the
non-conservative Clostridial toxin enzymatic domain variant is
based, that possess at least 50% amino acid identity, 65% amino
acid identity, 75% amino acid identity, 85% amino acid identity or
95% amino acid identity to the reference Clostridial toxin
enzymatic domain on which the non-conservative Clostridial toxin
enzymatic domain variant is based. Non-limiting examples of a
non-conservative Clostridial toxin enzymatic domain variant
include, e.g., non-conservative BoNT/A enzymatic domain variants,
non-conservative BoNT/B enzymatic domain variants, non-conservative
BoNT/C1 enzymatic domain variants, non-conservative BoNT/D
enzymatic domain variants, non-conservative BoNT/E enzymatic domain
variants, non-conservative BoNT/F enzymatic domain variants,
non-conservative BoNT/G enzymatic domain variants, and
non-conservative TeNT enzymatic domain variants.
[0111] As used herein, the term "Clostridial toxin enzymatic domain
chimeric" means a polypeptide comprising at least a portion of a
Clostridial toxin enzymatic domain and at least a portion of at
least one other polypeptide to form a toxin enzymatic domain with
at least one property different from the reference Clostridial
toxin enzymatic domains of Table 1, with the proviso that this
Clostridial toxin enzymatic domain chimeric is still capable of
specifically targeting the core components of the neurotransmitter
release apparatus and thus participate in executing the overall
cellular mechanism whereby a Clostridial toxin proteolytically
cleaves a substrate. Such Clostridial toxin enzymatic domain
chimerics are described in, e.g., Lance E. Steward et al.,
Leucine-based Motif and Clostridial Toxins, U.S. Patent Publication
2003/0027752 (Feb. 6, 2003); Lance E. Steward et al., Clostridial
Neurotoxin Compositions and Modified Clostridial Neurotoxins, U.S.
Patent Publication 2003/0219462 (Nov. 27, 2003); and Lance E.
Steward et al., Clostridial Neurotoxin Compositions and Modified
Clostridial Neurotoxins, U.S. Patent Publication 2004/0220386 (Nov.
4, 2004), each of which is incorporated by reference in its
entirety.
[0112] As used herein, the term "active Clostridial toxin enzymatic
domain fragment" means any of a variety of Clostridial toxin
fragments comprising the enzymatic domain can be useful in aspects
of the present invention with the proviso that these enzymatic
domain fragments can specifically target the core components of the
neurotransmitter release apparatus and thus participate in
executing the overall cellular mechanism whereby a Clostridial
toxin proteolytically cleaves a substrate. The enzymatic domains of
Clostridial toxins are approximately 420-460 amino acids in length
and comprise an enzymatic domain (Table 1). Research has shown that
the entire length of a Clostridial toxin enzymatic domain is not
necessary for the enzymatic activity of the enzymatic domain. As a
non-limiting example, the first eight amino acids of the BoNT/A
enzymatic domain (residues 1-8 of SEQ ID NO: 1) are not required
for enzymatic activity. As another non-limiting example, the first
eight amino acids of the TeNT enzymatic domain (residues 1-8 of SEQ
ID NO: 8) are not required for enzymatic activity. Likewise, the
carboxyl-terminus of the enzymatic domain is not necessary for
activity. As a non-limiting example, the last 32 amino acids of the
BoNT/A enzymatic domain (residues 417-448 of SEQ ID NO: 1) are not
required for enzymatic activity. As another non-limiting example,
the last 31 amino acids of the TeNT enzymatic domain (residues
427-457 of SEQ ID NO: 8) are not required for enzymatic activity.
Thus, aspects of this embodiment can include Clostridial toxin
enzymatic domains comprising an enzymatic domain having a length
of, e.g., at least 350 amino acids, at least 375 amino acids, at
least 400 amino acids, at least 425 amino acids and at least 450
amino acids. Other aspects of this embodiment can include
Clostridial toxin enzymatic domains comprising an enzymatic domain
having a length of, e.g., at most 350 amino acids, at most 375
amino acids, at most 400 amino acids, at most 425 amino acids and
at most 450 amino acids.
[0113] Any of a variety of sequence alignment methods can be used
to determine percent identity of naturally-occurring Clostridial
toxin enzymatic domain variants and non-naturally-occurring
Clostridial toxin enzymatic domain variants, including, without
limitation, global methods, local methods and hybrid methods, such
as, e.g., segment approach methods. Protocols to determine percent
identity are routine procedures within the scope of one skilled in
the art and from the teaching herein.
[0114] Global methods align sequences from the beginning to the end
of the molecule and determine the best alignment by adding up
scores of individual residue pairs and by imposing gap penalties.

conserved motifs shared by all of the input sequences. Non-limiting

e.g., Ivo Van Walle et al., Align-M--A New Algorithm for Multiple
Alignment of Highly Divergent Sequences, 20(9) Bioinformatics:

local alignment methods. Non-limiting methods include, e.g.,

[0158] The "translocation element" comprises a portion of a
clostridial neurotoxin heavy chain having a translocation activity.
By "translocation" is meant the ability to facilitate the transport
of a polypeptide through a vesicular membrane, thereby exposing
some or all of the polypeptide to the cytoplasm. In the various
botulinum neurotoxins translocation is thought to involve an
allosteric conformational change of the heavy chain caused by a
decrease in pH within the endosome. This conformational change
appears to involve and be mediated by the N terminal half of the
heavy chain and to result in the formation of pores in the
vesicular membrane; this change permits the movement of the
proteolytic light chain from within the endosomal vesicle into the
cytoplasm. See e.g., Lacy, et al., Nature Struct. Biol. 5:898-902
(October 1998).
[0159] The amino acid sequence of the translocation-mediating
portion of the botulinum neurotoxin heavy chain is known to those
of skill in the art; additionally, those amino acid residues within
this portion that are known to be essential for conferring the
translocation activity are also known. It would therefore be well
within the ability of one of ordinary skill in the art, for
example, to employ the naturally occurring N-terminal peptide half
of the heavy chain of any of the various Clostridium tetanus or
Clostridium botulinum neurotoxin subtypes as a translocation
element, or to design an analogous translocation element by
aligning the primary sequences of the N-terminal halves of the
various heavy chains and selecting a consensus primary
translocation sequence based on conserved amino acid, polarity,
steric and hydrophobicity characteristics between the
sequences.
[0160] Aspects of the present invention provide, in part, a
Clostridial toxin translocation domain. As used herein, the term
"Clostridial toxin translocation domain" means any Clostridial
toxin polypeptide that can execute the translocation step of the
intoxication process that mediates Clostridial toxin light chain
translocation. Thus, a Clostridial toxin translocation domain
facilitates the movement of a Clostridial toxin light chain across
a membrane and encompasses the movement of a Clostridial toxin
light chain through the membrane an intracellular vesicle into the
cytoplasm of a cell. Non-limiting examples of a Clostridial toxin
translocation domain include, e.g., a BoNT/A translocation domain,
a BoNT/B translocation domain, a BoNT/C1 translocation domain, a
BoNT/D translocation domain, a BoNT/E translocation domain, a
BoNT/F translocation domain, a BoNT/G translocation domain, a TeNT
translocation domain, a BaNT translocation domain, and a BuNT
translocation domain. Other non-limiting examples of a Clostridial
toxin translocation domain include, e.g., amino acids 449-873 of
SEQ ID NO: 1, amino acids 442-860 of SEQ ID NO: 2, amino acids
450-868 of SEQ ID NO: 3, amino acids 446-864 of SEQ ID NO: 4, amino
acids 423-847 of SEQ ID NO: 5, amino acids 440-866 of SEQ ID NO: 6,
amino acids 447-865 of SEQ ID NO: 7, amino acids 458-881 of SEQ ID
NO: 8, amino acids 432-857 of SEQ ID NO: 9, and amino acids 423-847
of SEQ ID NO: 10.
[0161] A Clostridial toxin translocation domain includes, without
limitation, naturally occurring Clostridial toxin translocation
domain variants, such as, e.g., Clostridial toxin translocation
domain isoforms and Clostridial toxin translocation domain
subtypes; non-naturally occurring Clostridial toxin translocation
domain variants, such as, e.g., conservative Clostridial toxin
translocation domain variants, non-conservative Clostridial toxin
translocation domain variants, Clostridial toxin translocation
domain chimerics, active Clostridial toxin translocation domain
fragments thereof, or any combination thereof.
[0162] As used herein, the term "Clostridial toxin translocation
domain variant," whether naturally-occurring or
non-naturally-occurring, means a Clostridial toxin translocation
domain that has at least one amino acid change from the
corresponding region of the disclosed reference sequences (Table 1)
and can be described in percent identity to the corresponding
region of that reference sequence. Unless expressly indicated, all
Clostridial toxin translocation domain variants disclosed in the
present specification are capable of executing the translocation
step of the intoxication process that mediates Clostridial toxin
light chain translocation. As non-limiting examples, a BoNT/A
translocation domain variant comprising amino acids 449-873 of SEQ
ID NO: 1 will have at least one amino acid difference, such as,
e.g., an amino acid substitution, deletion or addition, as compared
to the amino acid region 449-873 of SEQ ID NO: 1; a BoNT/B
translocation domain variant comprising amino acids 442-860 of SEQ

translocation domain variant comprising amino acids 450-868 of SEQ
ID NO: 3 will have at least one amino acid difference, such as,
e.g., an amino acid substitution, deletion or addition, as compared

translocation domain variant comprising amino acids 447-865 of SEQ

ID NO: 10 will have at least one amino acid difference, such as,
e.g., an amino acid substitution, deletion or addition, as compared
to the amino acid region 423-847 of SEQ ID NO: 10.
[0163] It is recognized by those of skill in the art that within
each serotype of Clostridial toxin there can be naturally occurring
Clostridial toxin translocation domain variants that differ
somewhat in their amino acid sequence, and also in the nucleic
acids encoding these proteins. For example, there are presently
four BoNT/A subtypes, BoNT/A1, BoNT/A2, BoNT/A3 and BoNT/A4, with
specific translocation domain subtypes showing approximately 87%
amino acid identity when compared to another BoNT/A translocation
domain subtype. As used herein, the term "naturally occurring
Clostridial toxin translocation domain variant" means any
Clostridial toxin translocation domain produced by a
naturally-occurring process, including, without limitation,
Clostridial toxin translocation domain isoforms produced from
alternatively-spliced transcripts, Clostridial toxin translocation
domain isoforms produced by spontaneous mutation and Clostridial
toxin translocation domain subtypes. A naturally occurring
Clostridial toxin translocation domain variant can function in
substantially the same manner as the reference Clostridial toxin
translocation domain on which the naturally occurring Clostridial
toxin translocation domain variant is based, and can be substituted
for the reference Clostridial toxin translocation domain in any
aspect of the present invention. A naturally occurring Clostridial
toxin translocation domain variant may substitute one or more amino
acids, two or more amino acids, three or more amino acids, four or
more amino acids, five or more amino acids, ten or more amino
acids, 20 or more amino acids, 30 or more amino acids, 40 or more
amino acids, 50 or more amino acids or 100 or more amino acids from
the reference Clostridial toxin translocation domain on which the
naturally occurring Clostridial toxin translocation domain variant
is based. A naturally occurring Clostridial toxin translocation
domain variant can also substitute at least 10 contiguous amino
acids, at least 15 contiguous amino acids, at least 20 contiguous
amino acids, or at least 25 contiguous amino acids from the
reference Clostridial toxin translocation domain on which the
naturally occurring Clostridial toxin translocation domain variant
is based, that possess at least 50% amino acid identity, 65% amino
acid identity, 75% amino acid identity, 85% amino acid identity or
95% amino acid identity to the reference Clostridial toxin
translocation domain on which the naturally occurring Clostridial
toxin translocation domain variant is based.
[0164] A non-limiting examples of a naturally occurring Clostridial
toxin translocation domain variant is a Clostridial toxin
translocation domain isoform such as, e.g., a BoNT/A translocation
domain isoform, a BoNT/B translocation domain isoform, a BoNT/C1
translocation domain isoform, a BoNT/D translocation domain
isoform, a BoNT/E translocation domain isoform, a BoNT/F
translocation domain isoform, a BoNT/G translocation domain
isoform, a TeNT translocation domain isoform, a BaNT translocation
domain isoform, and a BuNT translocation domain isoform. A
Clostridial toxin translocation domain isoform can function in
substantially the same manner as the reference Clostridial toxin
translocation domain on which the Clostridial toxin translocation
domain isoform is based, and can be substituted for the reference
Clostridial toxin translocation domain in any aspect of the present
invention.
[0165] Another non-limiting examples of a naturally occurring
Clostridial toxin translocation domain variant is a Clostridial
toxin translocation domain subtype such as, e.g., a translocation
domain from subtype BoNT/A1, BoNT/A2, BoNT/A3 and BoNT/A4; a
translocation domain from subtype BoNT/B1, BoNT/B2, BoNT/B bivalent
and BoNT/B nonproteolytic; a translocation domain from subtype
BoNT/C1-1 and BoNT/C1-2; a translocation domain from subtype
BoNT/E1, BoNT/E2 and BoNT/E3; and a translocation domain from
subtype BoNT/F1, BoNT/F2, BoNT/F3 and BoNT/F4. A Clostridial toxin
translocation domain subtype can function in substantially the same
manner as the reference Clostridial toxin translocation domain on
which the Clostridial toxin translocation domain subtype is based,
and can be substituted for the reference Clostridial toxin
translocation domain in any aspect of the present invention.
[0166] As used herein, the term "non-naturally occurring
Clostridial toxin translocation domain variant" means any
Clostridial toxin translocation domain produced with the aid of
human manipulation, including, without limitation, Clostridial
toxin translocation domains produced by genetic engineering using
random mutagenesis or rational design and Clostridial toxin
translocation domains produced by chemical synthesis. Non-limiting
examples of non-naturally occurring Clostridial toxin translocation
domain variants include, e.g., conservative Clostridial toxin
translocation domain variants, non-conservative Clostridial toxin
translocation domain variants, Clostridial toxin translocation
domain chimeric variants and active Clostridial toxin translocation
domain fragments.
[0167] As used herein, the term "conservative Clostridial toxin
translocation domain variant" means a Clostridial toxin
translocation domain that has at least one amino acid substituted
by another amino acid or an amino acid analog that has at least one
property similar to that of the original amino acid from the
reference Clostridial toxin translocation domain sequence (Table
1). Examples of properties include, without limitation, similar
size, topography, charge, hydrophobicity, hydrophilicity,
lipophilicity, covalent-bonding capacity, hydrogen-bonding
capacity, a physicochemical property, of the like, or any
combination thereof. A conservative Clostridial toxin translocation
domain variant can function in substantially the same manner as the
reference Clostridial toxin translocation domain on which the
conservative Clostridial toxin translocation domain variant is
based, and can be substituted for the reference Clostridial toxin
translocation domain in any aspect of the present invention. A
conservative Clostridial toxin translocation domain variant may

or more amino acids, four or more amino acids, five or more amino
acids, ten or more amino acids, 20 or more amino acids, 30 or more
amino acids, 40 or more amino acids, 50 or more amino acids, 100 or
more amino acids, 200 or more amino acids, 300 or more amino acids,
400 or more amino acids, or 500 or more amino acids from the
reference Clostridial toxin translocation domain on which the
conservative Clostridial toxin translocation domain variant is
based. A conservative Clostridial toxin translocation domain
variant can also substitute at least 10 contiguous amino acids, at
least 15 contiguous amino acids, at least 20 contiguous amino
acids, or at least 25 contiguous amino acids from the reference
Clostridial toxin translocation domain on which the conservative
Clostridial toxin translocation domain variant is based, that
possess at least 50% amino acid identity, 65% amino acid identity,
75% amino acid identity, 85% amino acid identity or 95% amino acid
identity to the reference Clostridial toxin translocation domain on
which the conservative Clostridial toxin translocation domain
variant is based. Non-limiting examples of a conservative
Clostridial toxin translocation domain variant include, e.g.,
conservative BoNT/A translocation domain variants, conservative
BoNT/B translocation domain variants, conservative BoNT/C1
translocation domain variants, conservative BoNT/D translocation
domain variants, conservative BoNT/E translocation domain variants,
conservative BoNT/F translocation domain variants, conservative
BoNT/G translocation domain variants, conservative TeNT
translocation domain variants, conservative BaNT translocation
domain variants, and conservative BuNT translocation domain
variants.
[0168] As used herein, the term "non-conservative Clostridial toxin
translocation domain variant" means a Clostridial toxin
translocation domain in which 1) at least one amino acid is deleted
from the reference Clostridial toxin translocation domain on which
the non-conservative Clostridial toxin translocation domain variant
is based; 2) at least one amino acid added to the reference
Clostridial toxin translocation domain on which the
non-conservative Clostridial toxin translocation domain is based;
or 3) at least one amino acid is substituted by another amino acid
or an amino acid analog that does not share any property similar to
that of the original amino acid from the reference Clostridial
toxin translocation domain sequence (Table 1). A non-conservative
Clostridial toxin translocation domain variant can function in
substantially the same manner as the reference Clostridial toxin
translocation domain on which the non-conservative Clostridial
toxin translocation domain variant is based, and can be substituted
for the reference Clostridial toxin translocation domain in any
aspect of the present invention. A non-conservative Clostridial
toxin translocation domain variant can delete one or more amino
acids, two or more amino acids, three or more amino acids, four or
more amino acids, five or more amino acids, and ten or more amino
acids from the reference Clostridial toxin translocation domain on
which the non-conservative Clostridial toxin translocation domain
variant is based. A non-conservative Clostridial toxin
translocation domain variant can add one or more amino acids, two
or more amino acids, three or more amino acids, four or more amino
acids, five or more amino acids, and ten or more amino acids to the
reference Clostridial toxin translocation domain on which the
non-conservative Clostridial toxin translocation domain variant is
based. A non-conservative Clostridial toxin translocation domain
variant may substitute one or more amino acids, two or more amino
acids, three or more amino acids, four or more amino acids, five or
more amino acids, ten or more amino acids, 20 or more amino acids,
30 or more amino acids, 40 or more amino acids, 50 or more amino
acids, 100 or more amino acids, 200 or more amino acids, 300 or
more amino acids, 400 or more amino acids, or 500 or more amino
acids from the reference Clostridial toxin translocation domain on
which the non-conservative Clostridial toxin translocation domain
variant is based. A non-conservative Clostridial toxin
translocation domain variant can also substitute at least 10
contiguous amino acids, at least 15 contiguous amino acids, at
least 20 contiguous amino acids, or at least 25 contiguous amino
acids from the reference Clostridial toxin translocation domain on
which the non-conservative Clostridial toxin translocation domain
variant is based, that possess at least 50% amino acid identity,
65% amino acid identity, 75% amino acid identity, 85% amino acid
identity or 95% amino acid identity to the reference Clostridial
toxin translocation domain on which the non-conservative
Clostridial toxin translocation domain variant is based.

translocation domain variant include, e.g., non-conservative BoNT/A
translocation domain variants, non-conservative BoNT/B
translocation domain variants, non-conservative BoNT/C1
translocation domain variants, non-conservative BoNT/D

domain chimeric" means a polypeptide comprising at least a portion
of a Clostridial toxin translocation domain and at least a portion
of at least one other polypeptide to form a toxin translocation
domain with at least one property different from the reference
Clostridial toxin translocation domains of Table 1, with the
proviso that this Clostridial toxin translocation domain chimeric
is still capable of specifically targeting the core components of
the neurotransmitter release apparatus and thus participate in
executing the overall cellular mechanism whereby a Clostridial
toxin proteolytically cleaves a substrate.
[0170] As used herein, the term "active Clostridial toxin
translocation domain fragment" means any of a variety of
Clostridial toxin fragments comprising the translocation domain can
be useful in aspects of the present invention with the proviso that
these active fragments can facilitate the release of the LC from
intracellular vesicles into the cytoplasm of the target cell and
thus participate in executing the overall cellular mechanism
whereby a Clostridial toxin proteolytically cleaves a substrate.
The translocation domains from the heavy chains of Clostridial
toxins are approximately 410-430 amino acids in length and comprise
a translocation domain (Table 1). Research has shown that the
entire length of a translocation domain from a Clostridial toxin
heavy chain is not necessary for the translocating activity of the
translocation domain. Thus, aspects of this embodiment can include
Clostridial toxin translocation domains comprising a translocation
domain having a length of, e.g., at least 350 amino acids, at least
375 amino acids, at least 400 amino acids and at least 425 amino
acids. Other aspects of this embodiment can include Clostridial
toxin translocation domains comprising translocation domain having
a length of, e.g., at most 350 amino acids, at most 375 amino
acids, at most 400 amino acids and at most 425 amino acids.
[0171] Any of a variety of sequence alignment methods can be used
to determine percent identity of naturally-occurring Clostridial
toxin translocation domain variants and non-naturally-occurring
Clostridial toxin translocation domain variants, including, without
limitation, global methods, local methods and hybrid methods, such
as, e.g., segment approach methods. Protocols to determine percent
identity are routine procedures within the scope of one skilled in
the art and from the teaching herein.
[0172] Thus, in an embodiment, a modified Clostridial toxin
disclosed in the present specification comprises a Clostridial
toxin translocation domain. In an aspect of this embodiment, a

[0213] By "binding element" is meant an amino acid sequence region
able to preferentially bind to a cell surface marker characteristic
of the target cell under physiological conditions. The cell surface
marker may comprise a polypeptide, a polysaccharide, a lipid, a
glycoprotein, a lipoprotein, or may have structural characteristics
of more than one of these. By "preferentially interact" is meant
that the disassociation constant (K.sub.d) of the binding element
for the cell surface marker is at least one order of magnitude less
than that of the binding element for any other cell surface marker.
Preferably, the disassociation constant is at least 2 orders of
magnitude less, even more preferably the disassociation constant is
at least 3 orders of magnitude less than that of the binding
element for any other cell surface marker to which the neurotoxin
or modified neurotoxin is exposed. Examples of binding elements are

[0355] It is envisioned that a modified Clostridial toxin disclosed
in the present specification can comprise a binding element in any
and all locations with the proviso that modified Clostridial toxin
is capable of performing the intoxication process. Non-limiting
examples include, locating a binding element at the amino terminus
of a modified Clostridial toxin; locating a binding element between
a Clostridial toxin therapeutic element and a translocation element
of a modified Clostridial toxin; and locating a binding element at
the carboxyl terminus of a modified Clostridial toxin. Other
non-limiting examples include, locating a binding element between a
Clostridial toxin enzymatic domain and a Clostridial toxin
translocation domain of a modified Clostridial toxin. The enzymatic
domain of naturally-occurring Clostridial toxins contains the
native start methionine. Thus, in domain organizations where the
enzymatic domain is not in the amino-terminal location an amino
acid sequence comprising the start methionine should be placed in
front of the amino-terminal domain. Likewise, where a binding
element is in the amino-terminal position, an amino acid sequence
comprising a start methionine and a protease cleavage site may be
operably-linked in situations in which a binding element requires a
free amino terminus, see, e.g., Shengwen Li et al., Degradable
Clostridial Toxins, U.S. patent application Ser. No. 11/572,512
(Jan. 23, 2007), which is hereby incorporated by reference in its
entirety. In addition, it is known in the art that when adding a
polypeptide that is operably-linked to the amino terminus of
another polypeptide comprising the start methionine that the
original methionine residue can be deleted.
[0356] Thus, in an embodiment, a modified Clostridial toxin can
comprise an amino to carboxyl single polypeptide linear order
comprising a binding element, a translocation element, an exogenous
protease cleavage site and a therapeutic element (FIG. 20A). In an
aspect of this embodiment, a modified Clostridial toxin can

domain, an exogenous protease cleavage site and a Clostridial toxin
enzymatic domain.
[0357] In another embodiment, a modified Clostridial toxin can
comprise an amino to carboxyl single polypeptide linear order
comprising a binding element, a therapeutic element, an exogenous
protease cleavage site, and a translocation element (FIG. 20B). In
an aspect of this embodiment, a modified Clostridial toxin can
comprise an amino to carboxyl single polypeptide linear order
comprising a binding element, a Clostridial toxin enzymatic domain,
an exogenous protease cleavage site, a Clostridial toxin

[0358] In yet another embodiment, a modified Clostridial toxin can
comprise an amino to carboxyl single polypeptide linear order
comprising a therapeutic element, an exogenous protease cleavage
site, a binding element, and a translocation element (FIG. 21A). In
an aspect of this embodiment, a modified Clostridial toxin can
comprise an amino to carboxyl single polypeptide linear order
comprising a Clostridial toxin enzymatic domain, an exogenous
protease cleavage site, a binding element, and a Clostridial toxin

element, an exogenous protease cleavage site and a Clostridial
toxin enzymatic domain.
[0360] In another embodiment, a modified Clostridial toxin can
comprise an amino to carboxyl single polypeptide linear order
comprising a therapeutic element, a binding element, an exogenous
protease cleavage site, and a translocation element (FIG. 21C). In
an aspect of this embodiment, a modified Clostridial toxin can
comprise an amino to carboxyl single polypeptide linear order
comprising a Clostridial toxin enzymatic domain, a binding element,
an exogenous protease cleavage site, a Clostridial toxin
translocation domain.
[0361] In yet another embodiment, a modified Clostridial toxin can
comprise an amino to carboxyl single polypeptide linear order
comprising a translocation element, a binding element, an exogenous
protease cleavage site and a therapeutic element (FIG. 21D). In an
aspect of this embodiment, a modified Clostridial toxin can
comprise an amino to carboxyl single polypeptide linear order
comprising a Clostridial toxin translocation domain, a binding
element, an exogenous protease cleavage site and a Clostridial
toxin enzymatic domain.
[0362] In still another embodiment, a modified Clostridial toxin
can comprise an amino to carboxyl single polypeptide linear order
comprising a therapeutic element, an exogenous protease cleavage
site, a translocation element, and a binding element (FIG. 22A). In
an aspect of this embodiment, a modified Clostridial toxin can
comprise an amino to carboxyl single polypeptide linear order
comprising a Clostridial toxin enzymatic domain, an exogenous
protease cleavage site, a Clostridial toxin translocation domain,
and a binding element.
[0363] In still another embodiment, a modified Clostridial toxin
can comprise an amino to carboxyl single polypeptide linear order
comprising a translocation element, an exogenous protease cleavage
site, a therapeutic element and a binding element, (FIG. 22B). In
an aspect of this embodiment, a modified Clostridial toxin can
comprise an amino to carboxyl single polypeptide linear order
comprising a Clostridial toxin translocation domain, a binding
element, an exogenous protease cleavage site and a Clostridial
toxin enzymatic domain.
[0364] In a particularly preferred embodiment, the single-chain
neurotoxin or neurotoxin derivative of the invention, altered as
indicated above, is further modified to remove other incidental
endogenous proteolytic sites such as those cleaved by trypsin, Arg
C protease, chymotrypsin, or host cell proteases. As indicated
below, modification of the primary amino acid sequences in these
regions to confer protease resistance can increase the yield of the
neurotoxin and reduce the toxicity of the single-chain neurotoxin
prior to cleavage and activation.
[0365] In another preferred embodiment, the recombinant modified
single-chain neurotoxin is further modified by joining the chain to
a binding tag comprising one member of a specific binding complex.
By "specific binding complex" is meant two or more chemical or
biochemical entities that will bind each other under defined
environmental conditions and which will not significantly bind
other chemical or biochemical entities present in the environment
under the same conditions. Examples of members of a specific
binding complex include, without limitation, an antibody and its
antigen, a lectin and its target carbohydrate, a nucleic acid
strand and its complementary nucleic acid strand, a cell surface
receptor and its ligand, a metal and a compound able to form a
coordination or chelation complex with that metal, and the
like.
[0366] In this embodiment, the binding tag may be joined to the
single-chain toxin through a linker, preferably a cleavable linker.
Examples of possible linkers, while not an exhaustive list, include
1) aliphatic dicarboxylic acids of the formula
HOOC--(CH.sub.2).sub.n--COOH, where n=1-12 (may be linked at a free
amino group); 2) HO--(CH.sub.2).sub.n--COOH, where n>10
(suitable for attachment at the amino terminus of the polypeptide),
3) substituted polybenzene structures, and 4) a
N-hydroxysuccinimide (NHS) ester linker. The use of an linker
containing an ester permits cleavage of the ester linker following
use in the purification of the single-chain neurotoxin under
relatively mild acidic conditions.
[0367] Alternatively, and most preferably, the binding tag may
comprise some or all of the amino acid sequence of an appropriately
chosen polypeptide coexpressed with the single-chain toxin as a
fusion protein; such polypeptides may comprise, without limitation,
the maltose binding domain of maltose binding protein (MBP), a
polyhistidine peptide like HIS.sub.6, the calmodilin binding domain
of calmodulin binding protein, the glutathione binding domain of
glutathione-S-transferase, FLAG, human Influenza virus
hemagluttinin (HA), human p62c-Myc protein (c MYC), Vesicular
Stomatitis Virus Glycoprotein (VSV-G), Substance P, glycoprotein-D
precursor of Herpes simplex virus (HSV), V5, AU1 and AU5,
streptavidin binding peptide (strep), and biotin or a biotinylation
sequence. Non-limiting examples of specific protocols for
selecting, making and using an appropriate binding peptide are
described in, e.g., Epitope Tagging, pp. 17.90-17.93 (Sambrook and
Russell, eds., Molecular Cloning A Laboratory Manual, Vol. 3, 3rd
ed. 2001); Antibodies: A Laboratory Manual (Edward Harlow &
David Lane, eds., Cold Spring Harbor Laboratory Press, 2nd ed.
1998); and Using Antibodies: A Laboratory Manual Portable Protocol
No. I (Edward Harlow & David Lane, Cold Spring Harbor
Laboratory Press, 1998). In addition, non-limiting examples of
binding tags as well as well-characterized reagents, conditions and
protocols are readily available from commercial vendors that
include, without limitation, BD Biosciences-Clontech, Palo Alto,
Calif.; BD Biosciences Pharmingen, San Diego, Calif.; Invitrogen,
Inc, Carlsbad, Calif.; QIAGEN, Inc., Valencia, Calif.; and
Stratagene, La Jolla, Calif. These protocols are routine procedures
well within the scope of one skilled in the art and from the
teaching herein.
[0368] Thus, in an embodiment, a modified Clostridial toxin
disclosed in the present specification can further comprise a
binding tag. In another embodiment, a modified Clostridial toxin
disclosed in the present specification can further comprises a
plurality of binding tags. In aspects of this embodiment, a
modified Clostridial toxin can comprise, e.g., at least 1 binding
tag, at least 2 binding tags, at least 3 binding tags, at least 4
binding tags or at least 5 binding tags. In other aspects of this
embodiment, a modified Clostridial toxin can comprise, e.g., at
most 1 binding tag, at most 2 binding tags, at most 3 binding tags,
at most 4 binding tags or at most 5 binding tags. In another aspect
of this embodiment, a modified Clostridial toxin can comprise one
or more copies of the same binding tag, one or more copies of
different binding tag, or any combination thereof.
[0369] The location of a binding tag can be in various positions,
including, without limitation, at the amino terminus of a modified
Clostridial toxin, within a modified Clostridial toxin, or at the
carboxyl terminus of a modified Clostridial toxin. Thus, in an
embodiment, a binding tag is located at the amino-terminus of a
modified Clostridial toxin. In such a location, a start methionine
should be placed in front of the binding tag. In addition, it is
known in the art that when adding a polypeptide that is
operably-linked to the amino terminus of another polypeptide
comprising the start methionine that the original methionine
residue can be deleted. This is due to the fact that the added
polypeptide will contain a new start methionine and that the
original start methionine may reduce optimal expression of the
fusion protein. In aspects of this embodiment, a binding tag
located at the amino-terminus of a modified Clostridial toxin
disclosed in the present specification can be, e.g., a FLAG
Express.TM. binding tag, a human Influenza virus hemagluttinin (HA)
binding tag, a human p62c-Myc protein (c MYC) binding tag, a
Vesicular Stomatitis Virus Glycoprotein (VSV-G) binding tag, a
Substance P binding tag, a glycoprotein-D precursor of Herpes
simplex virus (HSV) binding tag, a V5 binding tag, a AU1 binding
tag, a AU5 binding tag, a polyhistidine binding tag, a streptavidin
binding peptide binding tag, a biotin binding tag, a biotinylation
binding tag, a glutathione binding domain of
glutathione-S-transferase, a calmodulin binding domain of the
calmodulin binding protein or a maltose binding domain of the
maltose binding protein.
[0370] In another embodiment, an epitope-binding region is located
at the carboxyl-terminus of a modified Clostridial toxin. In
aspects of this embodiment, an epitope-binding region located at
the carboxyl-terminus of a modified Clostridial toxin disclosed in
the present specification can be, e.g., a FLAG Express.TM. binding
tag, a human Influenza virus hemagluttinin (HA) binding tag, a
human p62c-Myc protein (c MYC) binding tag, a Vesicular Stomatitis
Virus Glycoprotein (VSV-G) binding tag, a Substance P binding tag,
a glycoprotein-D precursor of Herpes simplex virus (HSV) binding
tag, a V5 binding tag, a AU1 binding tag, a AU5 binding tag, a
polyhistidine binding tag, a streptavidin binding peptide binding
tag, a biotin binding tag, a biotinylation binding tag, a
glutathione binding domain of glutathione-S-transferase, a
calmodulin binding domain of the calmodulin binding protein or a
maltose binding domain of the maltose binding protein.
[0371] Additionally, the binding tag may be constructed to have a
protease cleavage site between itself and either the amino terminus
or the carboxyl terminus of the single-chain toxin so as be
removable following purification of the peptide. The proteolytic
cleavage site may be designed to be cleaved by the same activator
protease chosen to nick the single-chain toxin between the H and L
chains.
[0372] It is therefore an object of the invention to provide a
recombinant activatible single-chain neurotoxin molecule that has
reduced toxicity compared to the native neurotoxin until activated
by reaction with a non-clostridial protease. The single-chain
neurotoxin is more easily purified, is less dangerous to handle in
the purification process, and can be optionally modified to give
the toxin more desirable properties.
[0373] It is also an object of the invention to provide an method
of making a recombinant activatable single-chain neurotoxin by
modifying the nucleotide sequence encoding the neurotoxin to
replace the native amino acid proteolytic cleavage sequence
separating the H and L chain with an amino acid sequence stable to
indigenous clostridial or host cell proteases but susceptible to
cleavage by chosen protease in vitro.
[0374] It is further an object of the present invention to provide
more stable neurotoxin polypeptides through modification of the
nucleotide sequence of the coding region of the H and L chains
thereof, removing incidental proteolytic cleavage sites by causing
the replacement of labile amino acids with other amino acid
residues which confer upon the toxin resistance to undesired
proteolytic degradation.
[0375] Additionally, it is an object of the invention to provide
methods of purifying recombinant neurotoxins as a single-chain by
joining the expressed single-chain neurotoxin to a binding moiety
comprising partner of a specific binding complex which can be used
in the affinity purification with the binding partner comprising
the other half of the binding complex. Purification can be
performed batch-wise or in a chromatography column. The binding
moiety may then be removed following the affinity step, and
separated from the neurotoxin.
[0376] It is also an object of the invention to provide
single-chain recombinant modified neurotoxin molecules for use as
therapeutic agents. The modified neurotoxin molecules may have an
altered target specificity or an altered activity compared to the
native neurotoxin from which it is derived, or both.
[0377] Another aspect of the present invention provides a method of
activating an activatable polypeptide disclosed in the present
specification, such method comprising the step of incubating the
activatable polypeptide with an exogenous protease, wherein the
exogenous protease can cleave the exogenous protease cleavage site
present in the polypeptide and wherein cleavage of the activatable
polypeptide by the exogenous protease converts the activatable
polypeptide from its single-chain polypeptide form into its
di-chain form, thereby activating the polypeptide.
[0378] Aspects of the present invention provide, in part, an
exogenous protease. As used herein, the term "exogenous protease"
means any protease capable of selectively cleaving the P1-P1'
scissile bond comprising the exogenous protease cleavage site, with
the proviso that the exogenous protease is not a human protease or
a protease being expressed by the host cell expressing a construct
encoding an activatable polypeptide disclosed in the present
specification. As used herein, the term "selectively" means having
a highly preferred activity or effect. Thus, with reference to an
exogenous protease, there is a discriminatory proteolytic cleavage
of the P1-P1' scissile bond comprising the exogenous protease
cleavage site. It is envisioned that any and all proteases capable
of selectively cleaving the P1-P1' scissile bond comprising the
exogenous protease cleavage site can be useful in the disclosed
methods. As a non-limiting example, a bovine enterokinse can
selectively cleave a bovine enterokinse cleavage site, a tobacco
etch virus protease can selectively cleave a tobacco etch virus
protease cleavage site, a human rhinovirus 3C protease can
selectively cleave a human rhinovirus 3C protease cleavage site, a
subtilisin can selectively cleave a subtilisin cleavage site, a
hydroxylamine can selectively cleave a hydroxylamine cleavage site,
and a SUMO/ULP-1 protease can selectively cleave a SUMO/ULP-1
protease cleavage site.
[0379] A therapeutic agent useful in the invention generally is
administered as a pharmaceutical acceptable composition comprising
a modified neurotoxin as disclosed in the present specification. As
used herein, the term "pharmaceutically acceptable" means any
molecular entity or composition that does not produce an adverse,
allergic or other untoward or unwanted reaction when administered
to an individual. As used herein, the term "pharmaceutically
acceptable composition" is synonymous with "pharmaceutical
composition" and means a therapeutically effective concentration of
an active ingredient, such as, e.g., any of the modified
neurotoxins disclosed in the present specification. A
pharmaceutical composition comprising a modified neurotoxin is
useful for medical and veterinary applications. A pharmaceutical
composition may be administered to a patient alone, or in
combination with other supplementary active ingredients, agents,
drugs or hormones. The pharmaceutical compositions may be
manufactured using any of a variety of processes, including,
without limitation, conventional mixing, dissolving, granulating,
dragee-making, levigating, emulsifying, encapsulating, entrapping,
and lyophilizing. The pharmaceutical composition can take any of a
variety of forms including, without limitation, a sterile solution,
suspension, emulsion, lyophilizate, tablet, pill, pellet, capsule,
powder, syrup, elixir or any other dosage form suitable for
administration.
[0380] It is also envisioned that a pharmaceutical composition
comprising a modified neurotoxin can optionally include a
pharmaceutically acceptable carriers that facilitate processing of
an active ingredient into pharmaceutically acceptable compositions.
As used herein, the term "pharmacologically acceptable carrier" is
synonymous with "pharmacological carrier" and means any carrier
that has substantially no long term or permanent detrimental effect
when administered and encompasses terms such as "pharmacologically
acceptable vehicle, stabilizer, diluent, additive, auxiliary or
excipient." Such a carrier generally is mixed with an active
compound, or permitted to dilute or enclose the active compound and
can be a solid, semi-solid, or liquid agent. It is understood that
the active ingredients can be soluble or can be delivered as a
suspension in the desired carrier or diluent. Any of a variety of
pharmaceutically acceptable carriers can be used including, without
limitation, aqueous media such as, e.g., water, saline, glycine,
hyaluronic acid and the like; solid carriers such as, e.g.,
mannitol, lactose, starch, magnesium stearate, sodium saccharin,
talcum, cellulose, glucose, sucrose, magnesium carbonate, and the
like; solvents; dispersion media; coatings; antibacterial and
antifungal agents; isotonic and absorption delaying agents; or any
other inactive ingredient. Selection of a pharmacologically
acceptable carrier can depend on the mode of administration. Except
insofar as any pharmacologically acceptable carrier is incompatible
with the active ingredient, its use in pharmaceutically acceptable
compositions is contemplated. Non-limiting examples of specific
uses of such pharmaceutical carriers can be found in PHARMACEUTICAL
DOSAGE FORMS AND DRUG DELIVERY SYSTEMS (Howard C. Ansel et al.,
eds., Lippincott Williams & Wilkins Publishers, 7 ed. 1999);
REMINGTON: THE SCIENCE AND PRACTICE OF PHARMACY (Alfonso R. Gennaro
ed., Lippincott, Williams & Wilkins, 20 ed. 2000); GOODMAN
& GILMAN'S THE PHARMACOLOGICAL BASIS OF THERAPEUTICS (Joel G.
Hardman et al., eds., McGraw-Hill Professional, 10th ed. 2001); and
HANDBOOK OF PHARMACEUTICAL EXCIPIENTS (Raymond C. Rowe et al., APhA
Publications, 4 edition 2003). These protocols are routine
procedures and any modifications are well within the scope of one
skilled in the art and from the teaching herein.
[0381] It is further envisioned that a pharmaceutical composition
disclosed in the present specification can optionally include,
without limitation, other pharmaceutically acceptable components
(or pharmaceutical components), including, without limitation,
buffers, preservatives, tonicity adjusters, salts, antioxidants,
osmolality adjusting agents, physiological substances,
pharmacological substances, bulking agents, emulsifying agents,
wetting agents, sweetening or flavoring agents, and the like.
Various buffers and means for adjusting pH can be used to prepare a
pharmaceutical composition disclosed in the present specification,
provided that the resulting preparation is pharmaceutically
acceptable. Such buffers include, without limitation, acetate
buffers, citrate buffers, phosphate buffers, neutral buffered
saline, phosphate buffered saline and borate buffers. It is
understood that acids or bases can be used to adjust the pH of a
composition as needed. Pharmaceutically acceptable antioxidants
include, without limitation, sodium metabisulfite, sodium
thiosulfate, acetylcysteine, butylated hydroxyanisole and butylated
hydroxytoluene. Useful preservatives include, without limitation,
benzalkonium chloride, chlorobutanol, thimerosal, phenylmercuric
acetate, phenylmercuric nitrate, a stabilized oxy chloro
composition, such as, e.g., PURITE.RTM. and chelants, such as,
e.g., DTPA or DTPA-bisamide, calcium DTPA, and CaNaDTPA-bisamide.
Tonicity adjustors useful in a pharmaceutical composition include,
without limitation, salts such as, e.g., sodium chloride, potassium
chloride, mannitol or glycerin and other pharmaceutically
acceptable tonicity adjustor. The pharmaceutical composition may be
provided as a salt and can be formed with many acids, including but
not limited to, hydrochloric, sulfuric, acetic, lactic, tartaric,
malic, succinic, etc. Salts tend to be more soluble in aqueous or
other protonic solvents than are the corresponding free base forms.
It is understood that these and other substances known in the art
of pharmacology can be included in a pharmaceutical composition
useful in the invention.
[0382] In an embodiment, a therapeutic agent is a pharmaceutical
composition comprising a modified neurotoxin. In an aspect of this
embodiment, a pharmaceutical composition comprises an unactivated,
single-chain for of the modified toxin. In another aspect of this
embodiment, a pharmaceutical composition comprises an activated
di-chain form of the modified toxin. In other aspects of this
embodiment, a pharmaceutical composition comprising a modified
neurotoxin further comprises a pharmacological carrier, a
pharmaceutical component, or both a pharmacological carrier and a
pharmaceutical component. In other aspects of this embodiment, a
pharmaceutical composition comprising a modified neurotoxin further
comprises at least one pharmacological carrier, at least one
pharmaceutical component, or at least one pharmacological carrier
and at least one pharmaceutical component.
[0383] It is also an object of the invention to provide a
single-chain activatable recombinant neurotoxin that may be more
easily purified than the wild type neurotoxin. Such a neurotoxin
permits the large scale preparation of properly folded highly pure
toxin for clinical use.
EXAMPLES
[0384] The following Examples serve to illustrate particular
embodiments of the invention, and do not limit the scope of the
invention defined in the claims in any way.
Example 1
Construction of an Expression Vector Containing a Single-Chain TeNT
Coding Region
[0385] The present invention can be exemplified describing the
construction of a plasmid that will express TeNT in E. coli as a
single protein that is readily purified, i.e., by affinity
chromatography. TeNT can be chosen as a pilot system because (i)
the availability of an excellent vaccine greatly reduces the risk
of its handling and (ii) it is the most comprehensively studied of
the toxins in terms of expressing HC and LC domains. However, those
of skill in the art will understand that the same or similar
strategies may be employed using any di-chain or binary toxin or
other bioactive molecule expressed as a single polypeptide and
activated by proteolytic cleavage. Single chain molecules were
constructed containing the wild type TeNT L chain and a mutated
version of the TeNT light chain wherein a glutamic acid residue at
position 234 is changed to an alanine (termed "E234A", Ala.sup.234,
or "the E234A mutant light chain"), respectively. This latter
mutation results in an inactive TeNT light chain, and a plasmid
encoding the E234A mutant light chain (pMAL-E234A) was constructed
as described in Li et al., Biochemistry 33:7014-7020 (1994)(hereby
incorporated by reference herein). The following protocol is used
for the construction of each single-chain toxin.
[0386] The vector pTrcHisA, purchased from Invitrogen, is modified
using a Stratagene QuickChange.RTM. site-directed mutagenesis kit
(for site-directed mutagenesis techniques, see e.g., Smith et al.,
J. Biol. Chem. 253:6651-6560 (1979); incorporated by reference
herein in its entirety) to create two extra restriction sites (SalI
and HindIII) upstream of the nucleotides encoding a pre-existing
enterokinase (EK) cleavage site. The plasmid also contains a
translational start codon (ATG) followed by a run of codons
encoding 6 histidine residues immediately upstream of the
enterokinase cleavage site. A multiple cloning site containing Bam
HI, XhoI, Bgl II, Pst I, Kpn I, Eco RI BstB I and Hind III cleavage
sites is located immediately downstream of the EK site; the Hind
III site is removed by site-directed mutagenesis. The following
primers are employed to insert the restriction sites (underlined)
upstream of the EK cleavage site:
TABLE-US-00003 (SEQ ID NO: 67)
GACTGGTGGACAGCAAGTCGACCGGAAGCTTTACGACGATGACG, Sal I Hind III and
(SEQ ID NO: 68) CGTCATCGTCGTAAAGCTTCCGGTCGACTTGCTGTCCACCAGTC Hind
III Sal I
[0387] The resulting plasmid contains both Sal I and Hind III sites
located at the 5' side of the nucleotide sequence encoding the
bovine enterokinase (EK) cleavage site.
[0388] The nucleotide sequence encoding the wild-type TeNT L chain
is obtained from plasmid pMAL-LC, described in Li et al.,
Biochemistry 33, 7014-7020 (1994), incorporated by reference
herein. The plasmid encodes the TeNT light chain as a fusion
protein with maltose binding protein (MBP) located immediately
upstream of the coding sequence for the L chain. The MBP and L
chain portions of the fusion protein are designed to contain the
cleavage site for human blood coagulation factor Xa
(Ile-Glu-Gly-Arg) to facilitate removal of the MBP once affinity
purification has been performed.
[0389] The DNA fragment containing the coding sequence of the L
chain is excised from plasmid pMAL-LC by digesting the plasmid with
Sal I and Hind III, gel purifying the resulting DNA fragment
containing the L chain, and ligating this fragment into plasmid
pTrcHisA at the newly created Sal I and Hind III sites upstream of
the EK site. This fragment results in the excission of the maltose
binding protein sequences from the N terminus of the L chain.
[0390] An identical procedure is used to subclone the DNA fragment
containing a mutant L chain from plasmid pMAL-LC-Ala.sup.234, in
which a single amino acid change is made at amino acid 234 of the L
chain, substituting the native glutamic acid with alanine. This
change is sufficient to abrogate the zinc endopeptidase activity of
the L chain, and to render non-toxic a reconstituted tetanus toxin
containing native H chain and the Ala.sup.234 L chain.
[0391] The DNA fragment containing the H chain is obtained from
plasmid PMAL-HC; construction of this vector is described in Li et
al., J. Biochem. 125:1200-1208 (1999), hereby incorporated by
reference herein. Briefly, the gene encoding the H chain is
constructed by assembling three DNA fragments containing different
portions of the H chain coding sequence which had been cloned into
separate plasmids. The fragments comprising the amino terminal half
of the H are first amplified using standard polymerase chain
reaction methods (see, e.g., Mullis, U.S. Pat. No. 4,683,202 and
Mullis et al., U.S. Pat. No. 4,800,159, both incorporated by
reference herein in their entirety) and the following primers: PCR
primers a (containing a Xba I cleavage site) and b (containing a
Bgl II cleavage site) (SEQ ID NO: 113 and 114, respectively) are
used to amplify the H chain fragment contained in a plasmid termed
pTet8; PCR primers c (containing a Bgl II cleavage site) and d
(containing both a Hind III and a Sal I cleavage site) (SEQ ID NO:
115 and 116, respectively) are used to amplify the H chain fragment
contained in a plasmid termed pTet14. The nucleotide sequences of
these primer are provided below, with restriction sites
underlined.
TABLE-US-00004 (SEQ ID NO: 69) AATAGATCTAGATCATTAACAGATTTAGGA (a)
(SEQ ID NO: 70) TTCTAAAGATCTATACATTTGATAACT (b) (SEQ ID NO: 71)
ATGTATAGATCTTTAGAATATCAAGTA (c) (SEQ ID NO: 72)
ATCGATAAGCTTTTATCAGTCGACCCAACAATCCAGATTTTTAGA (d)
[0392] Following PCR amplification and gel purification of the
amplified H chain fragments, each fragment is digested with Bgl II
and ligated to yield the complete N terminal half of the H chain
coding region. This ligation product is then digested with Xba I
and Hind III and subcloned into the multiple cloning site of
pMAL-c2-T (the plasmid being also cut with Xba I and Hind III),
which is located downstream of the coding region for MBP and the
factor Xa site. pMAL-c2 is a commecially available vector well
known to those of skill in the art. The resulting plasmid is
PMAL-HN.
[0393] The entire H chain coding region is assembled as follows.
The PMAL-HN plasmid is digested with Sac I and Sal I to yield the
DNA fragment encoding the N-terminus of the H chain. Plasmid
pTet215 is digested with Sal I and Bam HI to yield the DNA fragment
encoding the H chain carboxyl terminus. The vector pMAL-c2-T is
digested with Sac I and Bam HI, and ligated to the digested H chain
fragments, which will assemble in the proper orientation due to the
use of distinct endonucleases. The resulting plasmid is
pMAL-HC.
[0394] The DNA fragments encoding the H and L chains (including
Ala.sup.234 L chain) are cut and purified directly from pMAL-LC or
pMALE234A and pMAL-HC constructs and subcloned into the modified
pTrcHisA vector described above. The H chain was first ligated into
the modified vector at the Bam HI site immediately downstream of
the EK site, and the resulting plasmid was gel purified. Following
digestion of this plasmid with Hind III and Sal I, the L chain was
ligated at a position just upstream of the EK cleavage site.
[0395] The resulting plasmid construct contains the nucleotide
sequence encoding the single-chain toxin protein, comprising (from
amino to carboxyl terminus): six histidine residues (the His tag),
followed by the L chain, an enterokinase cleavage site, and the H
chain. The translated junction between the L and H chains
containing the EK cleavage site (SEQ ID NO: 21) is shown below (in
the direction from N-terminus to C-terminus) and in FIG. 1.

L chain interchain loop H chain
[0396] To allow expression of the two chains as a single unit, a
nucleotide sequence comprising a stop codon present at the 3' end
of the L chain coding sequence in the pMAL-LC is removed by
site-directed mutagenesis using two primers (SEQ ID NO: 74 and 75),
resulting in a single reading frame containing both H and L
chains.

GTCATCGTCGTAAAGCTTTTCTCCTGCAGTTCTATT TTATCA (deleted stop codon;
non-coding strand)
[0397] The resulting pTrcHisA-based construct is transformed into
E. coli strain JM109 by heat shock using the method of Hanahan, and
transformant colonies are isolated on Luria agar plates containing
100 .mu.g/ml ampicillin. Plasmids are purified from these
transformants and the insertions are confirmed by analytical
restriction endonuclease digestion and agarose gel
electrophoresis.
Example 2
Expression and Physical Characterization of Single-Chain TeNT
[0398] Expression of the pTrcHisA-based single-chain TeNT construct
(under control of a hybrid trp/lac promoter) is induced by addition
of 1 mM IPTG (isopropyl thio-galactopyranoside) to a confluent
culture of a representative transformant clone in 200 ml Luria
broth containing 100 .mu.g/ml ampicillin and incubating further at
37.degree. C. for 16 hours before cell harvest by
centrifugation.
[0399] The cell pellets are resuspended in 30 ml Buffer A (20 mM
Na.sub.2PO.sub.4, 500 mM NaCl (pH 7.8)), then lysed by
ultrasonication at 4.degree. C., using 10-second bursts at a medium
setting. Insoluble debris is removed by centrifugation at
9,000.times.g for 30 min at 4.degree. C., and the supernatant
recovered by centrifugation.
[0400] The supernatant containing each single-chain construct is
incubated for 20 minutes at 22.degree. C. with 2 ml of nickel-ion
resin (Invitrogen Corp.) for affinity purification by means of
chelation between the histidine residues at the amino terminus of
the single-chain toxin molecule and the nickel. The resins were
then load onto mini columns and washed with 200 ml of washing
buffer (20 mM Na.sub.2PO.sub.4, 500 mM NaCl (pH 6.0)) to remove any
non-specifically bound material, the recombinant single-chain
proteins are eluted on 0.5 ml fractions with 8-15 ml of 100 mM
imidazole in Buffer A. The concentration of the eluted
single-chains was measured by Bradford's protein assay (Bio-Rad
Laboratories); approximately 1 milligram of the fusion protein was
recovered.
Example 3
SDS-PAGE and Western Blot Analysis of Recombinant Single-Chain
TeNT
[0401] The single-chain TeNT constructs are grown in Luria broth
containing ampicillin at 37.degree. C., and aliquots taken both
before and after induction of protein expression with IPTG. Crude
cell extracts are prepared for SDS-PAGE by dilution in sample
buffer under reducing conditions in the presence of
.beta.-mercaptoethanol (BME). Following SDS-PAGE electrophoresis,
the separated proteins are Western-blotted as follows: the proteins
are electrophoretically transferred to a polyvinylidenedifluoride
(PVDF) membrane using standard methods (see, e.g., Sambrook et al.,
Molecular Cloning, A Laboratory Manual (2d ed. Cold Spring Harbor
Laboratory Press 1989), hereby incorporated by reference in its
entirety), the membrane treated to reduce background Ig binding,
and then probed using an anti-His.sub.6 antibody, followed by
detection using an alkaline phosphatase-conjugated secondary
antibody and development with a
5-bromo-4-chloro-3-indolyl-phosphate/nitro blue tetrazolium
substrate.
[0402] As shown in lanes 1 and 2 of FIG. 2A, the Western blot
revealed no detectable TeNT expression before induction of protein
synthesis; by contrast, a single band of approximate molecular
weight 150 kDa was revealed in the aliquots taken following protein
induction (See lanes 3 and 4.) In FIG. 2A, lanes 1 and 3 are the WT
light chain construct and lanes 2 and 4 contain the E234A mutant
construct.
[0403] FIG. 2B is a Western blot of IPTG-induced cell extracts from
cells transformed with the E234A construct. Significantly, no
discernable lower molecular weight proteolytic cleavage products of
the light chain were observed, providing evidence for the relative
stability of the single-chain toxin following expression and
purification.
[0404] FIG. 3 shows the results of a second experiment, in which
affinity purified recombinant single-chain (SC) TeNT is nicked with
enterokinase as follows. Thirty micrograms of purified single-chain
toxin are incubated with 1 unit of enterokinase in a solution
containing 50 mM Tris-HCl (pH 8.0), 1 mM CaCl.sub.2 and 0.1%
Tween-20(v/v). As a control, the recombinant protein is incubated
in the same reaction mixture containing no EK. These samples, plus
an aliquot of native (non-recombinant) TeNT are subjected to
SDS-PAGE in an 8% polyacrylamide gel under either reducing (+BME)
or non-reducing (-BME) conditions. The resulting gel is used both
for a Western blot and subsequent detection using anti-H claim
antibodies (FIG. 3B), and direct staining with Coomassie Blue (FIG.
3A).
[0405] As indicated by FIG. 3, under non-reducing conditions all
three samples (Native TeNT (Lane 1), unnicked recombinant toxin
(Lane 2), and enterokinase nicked recombinant toxin (Lane 3)) will
migrate as doublets (apparently different conformers that resolve
into a single band upon reduction) with essentially
indistinguishable apparent molecular weights of about 150 kDa. The
non-reducing gel confirms that 1) high levels of expression are
obtained, 2) the disulfide bonds linking the light and heavy chains
are fully formed, and 3) the recombinant single-chain toxin is not
subject to observable proteolytic degradation.
[0406] By contrast, under reducing conditions wild-type and nicked
recombinant toxin yield an H chain having a molecular weight of
about 100 kDa by both Western blot and Coomassie staining.
Additionally, in the Coomassie stained gel, both of these samples
also show a lower molecular weight species of about 50 kDa,
corresponding to the L chain. The wild-type L chain will migrate
with a lower apparent molecular weight than that of the recombinant
L chain, which has 22 additional amino acid residues due to the
presence of the His.sub.6 moiety and a modified EK cleavage
site-containing interchain junction region. The unnicked
recombinant toxin (Lane 2) migrates as a single band with an
apparent molecular weight of about 150 kDa. Notably, no trace of
the unnicked toxin is seen in lane 3, indicating the effectiveness
of enterokinase treatment.
Example 4
In Vitro Toxin-induced Paralysis by Recombinant Single-Chain
TeNT
[0407] The biological activity of the recombinant TeNT is also
examined and compared to wild-type toxin using mouse phrenic nerve
hemi-diaphragm, since the native toxin is known to cause
neuromuscular paralysis, albeit at higher concentrations than act
in the CNS. For this experiment, mouse left phrenic
nerve-hemidiaphragm is dissected from mice (T/O strain, 4-week old
and .about.20 g in weight) and immediately transferred into a
closed circulatory superfusion system containing 10 ml of
Krebs-Ringer solution (118 mM NaCl, 4.7 mM KCl, 1.2 mM MgSO.sub.4,
2.5 mM CaCl.sub.2, 23.8 mM NaHCO.sub.4, 1.2 mM KH.sub.2PO.sub.4,
11.7 mM glucose (pH 7.4)), bubbled with 95% O.sub.2 and 5% CO.sub.2
and supplemented with 0.1% (w/v) bovine serum albumin to diminish
non-specific adsorption of the toxins (Li et al., Biochemistry
33:7014-7020 (1994)). The hemidiaphragms are kept in a bath
containing 10 ml Krebs-Ringer buffer at 37.degree. C. for 10
minutes before being exposed to 4 or 10 nM native TeNT ( and
.gradient., respectively) or 10 nM nicked recombinant TeNT ( ) or
10 nM un-nicked recombinant TeNT (.largecircle.), respectively.
(See FIG. 4).
[0408] Muscle twitch is evoked by supra-maximal stimulation of the
phrenic nerve with bipolar electrodes and recorded via a
force-displacement transducer (Lectromed, UK) connected to an
amplifier and computer system (MacLab, AD Instruments, UK).
Parameters of nerve stimulation are 0.2 Hz square waves of 0.1 msec
duration with 1.5-2.5 V amplitude. Toxin-induced paralysis of
neuromuscular transmission is quantified as the time required for
nerve-evoked muscle contraction to decrease to 10% (90% reduction)
of the original value.
[0409] As shown in FIG. 4, 10 nM recombinant nicked TeNT was found
to be as potent as 10 nM native toxin in blocking nerve-induced
muscle twitch, with the preparations yielding a 90% reduction in
muscle tension in approximately 170 minutes. Thus, this novel
preparation of TeNT expressed in E. coli at high level as a
single-chain, activatable polypeptide and purified by a simple
affinity chromatography step proved to be fully active by all the
criteria examined.
[0410] By contrast, 10 nM of the unnicked TeNT preparation require
approximately twice as long to reduce muscle tension, and was
approximately as active as 4 nM of the wild-type TeNT. As a
control, hemidiaphragms incubated with KR buffer and the trace
amount of enterokinase present in the experimental samples were
found to show negligible decrease in muscle tension over 5 hrs.
[0411] Thus, this experiment indicates that the unnicked TeNT is
considerably less toxic that either the wild type or recombinant
nicked protein in vitro.
Example 5
Further Modification of Single-Chain TeNT to Remove Proteolytic
Cleavage Sites Reduces Toxicity of Unnicked Recombinant Toxin
[0412] While the unnicked recombinant single-chain form of TeNT
displays reduced toxicity as compared to the nicked form, the
residual toxin activity probably arises from activation of the
toxin by additional proteases in vivo. To test this possibility,
sites in the single-chain toxin molecule susceptible to proteolytic
cleavage by trypsin and Arg C protease are identified by incubation
of single-chain TeNT with these enzymes as follows. Fifty
micrograms .mu.g of recombinant single-chain TeNT is incubated with
4 .mu.g of Arg-C at 37.degree. C. for 4 h; 0.1 .mu.g of trypsin at
37.degree. C. for 0.5 h; or buffer without protease as a control.
These reactions are terminated by the addition of SDS-PAGE sample
buffer containing 0.1% SDS followed by boiling for 5 minutes; then
the samples are subjected to SDS-PAGE, followed by a Western
electrophoretic transfer to a polyvinylidenedifluoride (PVDF)
membrane. The membrane is blotted with IgG specific for the
His.sub.6-tag and detected using a horseradish peroxidase staining
system.
[0413] As shown in FIG. 5, the Western blot reveals that trypsin
and Arg C protease yielded a L chain (and thus a H chain) fragment
of the same size. Additionally, the transfer of a duplicate gel was
stained for protein with Ponceau red and the H chain band of
approximate molecular weight 100 kDa was excised from each lane and
analysed by N-terminal sequencing.
[0414] In the recombinant single-chain TeNT, the LC and HC are
linked by 17 amino acids (GEKLYDDDDKDRWGSSR), followed by the
beginning of the H chain sequence (SLTDLGGEL . . . ). N-terminal
amino acid sequencing of the larger fragment produced by both
trypsin and Arg C protease reveal that first 5 amino acids of the
100 kDa trypsin and Arg C protease cleavage product protein are
SLTDL; thus, these proteases appear to cleave the single-chain
toxin between the R--S bond (see FIG. 1) so as to liberate the H
chain and the L chain containing the EK linker at its C terminus,
with this variant therefore yielding a di-chain toxin essentially
identical to the EK nicked toxin.
[0415] The arginine at the carboxy terminus of the EK linker
sequence is mutated by site-directed mutagenesis to a glycine
(R496G), and the resulting single-chain toxin polypeptide is
expressed and purified as above.
[0416] Titration of the 6 micrograms of the R496G mutated
single-chain (WT LC) toxin and the SC TeNT lacking such a mutation
against 0, 0.01, 0.1, 1, 10 .mu.g/ml of trypsin, followed by
SDS-PAGE and staining with Coomassie Brilliant Blue, yields the
cleavage pattern seen in FIG. 6. As can be seen, both single-chain
molecules are susceptible to typsin cleavage; however the R496G
mutant yields fewer fragments than the SC toxin not containing a
mutation in the loop region between the chains. For example, while
three trypsin peptide bands can clearly be seen near the light
chain band upon trypsin cleavage of the SC WT toxin, only two such
bands are seen in the R496G digests.
[0417] The fact that there exist remaining trypsin sites in the
R496G mutant SC toxin probably accounts for the fact that this
mutant does not cause the lowering of toxicity as compared to the
un-nicked SC toxin; both preparations give similar values in the
mouse lethality and neuromuscular paralysis assays described
above.
[0418] A different assay system is used to measure neurotoxin
activity toward CNS neurons, the cells naturally affected by TeNT.
The cells used are cerebellar neurons; these cells are
disassociated from the cerebella of 7 day old rats. Neurons are
suspended at 1-2.times.10.sup.6/mL in medium consisting of 3 parts
Basal Eagle Medium and 1 part of a buffer consisting of 40 mM
HEPES-NaOH (pH 7.3), 78.4 mM KCl, 37.6 mM D-glucose, 2.8 mM
CaCl.sub.2, 1.6 mM MgSO.sub.4 and 1.0 mM NaH.sub.2PO.sub.4, as well
as 1.times.N2 supplement, 1.0 mM L-glutamine, 60 units/mL
penicillin, 60 .mu.g/mL streptomycin and 5% (v/v) dialysed horse
serum. One milliliter of this cell suspension is added to 22 mm
diameter poly-D-lysine coated wells. Cytosine
.beta.-D-arabinofuranoside (Ara-C, 40 .mu.M) is added after 20-24
hours in 5% (v/v)CO.sub.2 culture, and neurons are maintained by
weekly replacement of the above-noted medium containing 40 .mu.M
Ara-C.
[0419] For each assay, neurons are cultured for at least 10 days in
vitro are washed four times with O.sub.2-gassed Krebs-Ringer HEPES
buffer (KRH, mM: 20 HEPES.NaOH pH7.4, 128 NaCl, 5 KCl, 1
NaH.sub.2PO.sub.4, 1.4 CaCl.sub.2, 1.2 mM MgSO.sub.4, 10 D-glucose
and 0.05 mg/mL BSA), and 0.5 mL of the latter buffer containing
0.25 .mu.Ci/mL [14C]-glutamine (i.e. the glutamate precursor) is
added. All steps are performed at 37.degree. C. After a 45 minute
labeling period, the medium is removed and the neurons washed four
times as before. Control and toxin-treated neurons are incubated
for 5 minutes at 37.degree. C. in KRH buffer containing either 1.4
mM Ca.sup.2+ or 0.5 mM EGTA (i.e. to assess Ca.sup.2+-independent
release); aliquots are then removed and retained for assessment of
[.sup.14C]-glutamate content by scintillation counting. Immediately
after removal of the above basal medium, a modified KRH buffer
containing 50 mM KCl (containing a lowered 83 mM NaCl content in
order to maintain a normal osmotic potential) and either 1.4
Ca.sup.2+ or 0.5 mM EGTA are added for a 5 minute stimulation
period. Finally, neurons were solubilized with 20 mM EGTA.NaOH pH
7.5 containing 1% (w/v) SDS, and aliquots subjected to
scintillation counting in order to calculate their remaining
radioactive contents. The amounts of .sup.14C-glutamate in basal
and stimulated samples are expressed as percentages relative to the
calculated total cell content. The percentage [.sup.14C]-glutamate
contents in EGTA-containing buffer are subtracted from the values
recorded in Ca.sup.2+-containing samples in order to calculate the
relevant Ca.sup.2+-dependent component of release and in turn the
latter basal readings are subtracted from values obtained for 50 mM
KCl samples to yield the K.sup.+-evoked Ca.sup.2+-dependent
glutamate release component.
[0420] FIG. 8 demonstrates the ability of the recombinant toxin to
inhibit neurotransmitter release. Cerebellar neurons, maintained
for 10 days in vitro, were washed twice with ice-cold KRH buffer
containing 5 mM Mg.sup.2+ and 0.5 mM Ca.sup.2+, then exposed in
this buffer to the specified concentrations of ( ) native TeNT,
(.smallcircle.) EK-nicked TeNT R496G, () single-chain unnicked
TeNT, or (.gradient.) EK-nicked TeNT E234A for 60 min at 4.degree.
C. (see FIG. 8). Native TeNT (0.2 nM) was then added to the wells
specified and, after an additional 30 min, the neurons were washed
three times with ice-cold KRH buffer and incubated for 30 min at
37.degree. C. Subsequent assessment of K.sup.+-evoked
Ca.sup.2+-dependent neurotransmitter release was performed as
detailed above. The results of this assay are shown in FIG. 8.
[0421] When cerebellar neurons are exposed to nicked recombinant
TeNT, a dose-dependent inhibition of Ca.sup.++ dependent
transmitter release is seen with a potency similar to the native
toxin. Nicked recombinant SC TeNT, both WT and R496G, gave similar
values in this assay. Thus, while toxin activity in the unnicked
single-chain molecule is not abrogated through the removal of a
single trypsin cleavage site, the removal of additional such sites
is feasible in regions of the single-chain toxin to achieve an
activatable single-chain proform of the toxin that exhibits even
lower toxicity unless activated in vitro, when its full activity
can be achieved.
Example 7
Protease-Deficient TeNT Mutant Antagonises the Actions of TeNT on
Peripheral and Central Neurons
[0422] Table 3 shows the tabulated results of the indicated TeNT
constructs tested in three assays of toxin activity: ability to
cleave the HV62 peptide (which measures proteolytic activity only);
neuromuscular paralysis (which is an indication of the toxin
molecules' ability to enter the cell and thence to inhibit
neurotransmitter release), and mouse lethality upon intraperitoneal
injection of the various toxin constructs. The first two of these
assays was performed as described above.
[0423] The mouse lethality assay was performed essentially as
follows: Samples of recombinant purified single-chain TeNT, R496G
mutant TeNT, and E234A mutant TeNT are each divided into two
aliquots and one aliquot treated with enterokinase to nick the
toxin. All samples are serially diluted into 50 mM phosphate buffer
(pH 7.0), 150 mM NaCl and 0.25% (w/v) bovine serum albumin (BSA),
and the toxin preparations are injected into mice
intraperitoneally.
[0424] As shown in Table 3, the native and nicked TeNT preparations
were comparably active in the mouse lethality assay, having an
LD.sub.50 of about 1.times.10.sup.8/mg. The unnicked recombinant
toxin and unnicked R496G mutant were both about half as active.
Finally, the nicked E234A proteolytically inactive toxin was less
than 5.times.10.sup.7 fold less active.

proteolysis were measured using the RP-HPLC-based method detailed
in Foran et al. (1994). Incubations with 15 .mu.M of a synthetic
peptide corresponding to residues 33 to 94 of human VAMP-2 (HV62)
were performed at 37.degree. C. in 50 mM HEPES, NaOH pH 7.5
containing 2 mM DTT 0.2 mg ml.sup.-1 BSA and 50 .mu.M ZnCl.sub.2,
using the appropriate concentration of each reduced toxin
preparation required to proteolyze 10-15% of the substrate during a
30 min period. Data are means (.+-.S.D.; n = 4). .sup.bLD.sub.50 is
the amount of toxin that killed 50% of the injected mice within 4

.mu.g) at 22.degree. C. for 1 h. .sup.dThis v.degree. value
represents the detection limits of the RP-HPLC assay; no
proteolysis of HV62 was observed using prolonged incubations.
[0425] Purified SC E234A TeNT, in which the catalytic E at position
234 was replaced by an A, failed to show any detectable proteolysis
of a peptide containing residues 33 to 94 of human VAMP-2 (termed
HV62), either before or after nicking with EK. Accordingly, nicked
TeNT E234A proved to be devoid of toxicity in mice and unable to
inhibit transmitter release at the neuromuscular junction or from
cerebellar neurons.
[0426] Importantly, however, this mutant toxin retained the ability
to bind to the cell surface receptors on peripheral and central
neurons. Pre-incubation of cerebellar neurons with nicked (10-60
nM) or unnicked (7-40 nM) TeNT E234A at 4.degree. C. followed by
the addition of 0.2 nM native toxin, antagonized the native toxin's
inhibition of transmitter release at 37.degree. C. to similar
extents (FIG. 7).
[0427] As demonstrated in FIG. 9, exposure of mouse diaphragm to
100 nM TeNT E234A at 4.degree. C. for 60 minutes prior to adding 1
nM native toxin prolonged the time taken to cause neuromuscular
paralysis.
[0428] Mouse phrenic-nerve hemi-diaphragm was incubated in KR at
37.degree. C. with 20 nM recombinant TeNT E234A (.DELTA.) whilst
stimulating the nerve (0.2 Hz, 1.5-2.5v) and recording muscle
tension. For assessing competition, hemi-diaphragms were incubated
for 60 minutes at 4.degree. C. with MKR containing 0.1% BSA only
(.quadrature.), or the latter plus 100 nM nicked TeNT E234A
(.smallcircle.), before the addition of 1 nM native TeNT. Following
30 minutes exposure to the latter, the tissues were washed three
times with MKR and twice with KR. The temperature was raised to
37.degree. C. and the nerve stimulated with recording of the evoked
muscle twitch, as outlined above. This apparent competition for
toxin binding by the mutant seen with both tissues demonstrates
that the recombinant di-chain TeNT exhibits much higher affinity
for the cell surface receptors than the heavy chain or H.sub.c of
TeNT alone. These results suggest that the conformation of the
recombinant di-chain TeNT has high affinity to the cell surface
receptor.
[0429] Moreover, and very significantly, these data demonstrate
that recombinant molecules can be made according to the inventive
methods of the present patent application having specific binding
for the same cellular receptor as TeNT. However, such molecules
may, like the E234A mutant, be inactive as toxin molecules but will
retain the ability to be taken up by the target cell; thus serving
as potential transporter molecules.
Example 8
Expression of Single-Chain BoNT/A
[0430] Using methods similar to those described above, DNA
fragments containing the BoNT subtype A neurotoxin H and L chains
were ligated together, separated by the EK cleavage site. This
single-chain toxin coding sequence was inserted into a variety of
expression vectors containing different N terminal sequences and
promoters, as shown in Table 4, below.

Protein
[0431] The "fusion tags" each comprised a member of a specific
binding complex as a purification aid and to improve the solubility
and stability of the expressed protein. These plasmids were
transformed into the E. coli strains indicated in Table 4 and
expression of the single-chain toxin was monitored.
[0432] In another experiment, the single-chain BoNT/A construct was
inserted into plasmid pMAL-c2 between the Bam HI and Hind III
restriction sites, resulting in a coding sequence for a fusion
polypeptide containing the maltose binding protein at the N
terminus, followed by a Factor Xa cleavage site. Transformant JM
109 colonies were selected in Luria broth containing ampicillin.
Expression was induced by the addition of IPTG to a final
concentration of 0.3 mM. As for the TeNT construct, aliquots of the
cell culture were collected before and after induction, the cells
in each sample lysed by sonication, and the supernatant prepared
for SDS-PAGE under both reducing and non-reducing conditions.
Following electrophoresis to separate the proteins according to
apparent molecular weight, the gel was subjected to a Western blot
using an antibody raised against the H chain of BoNT/A. The Western
blot resulted in the appearance of an immunologically reactive
single-chain toxin band of apparent molecular weight approximately
200 kDa. Further modifications of the single-chain BoNT molecule to
eliminate fortuitous protease cleavage sites (similar to those
modifications made at the TeNT site labile to trypsin and Arg C
protease, described above) will result in even greater stability of
the single-chain BoNT/A molecule.

Construction of a Plasmid Vector Expressing BoNT/E
[0433] A plasmid expressing a single-chain recombinant version of
the neurotoxin from Clostridium botulinum subtype E(strain Beluga)
(BoNT/E) was constructed as follows. PCR primers were designed
based on the EMBL database cDNA sequence of the BoNT/E neurotoxin
(Genbank accession number X62089) This nucleotide sequence is
represented herein as SEQ ID NO: 76.

[0434] The forward primer had the following nucleotide base
sequence:
TABLE-US-00010 (SEQ ID NO: 77) CCCGGATCC CCA AAA ATT AAT AGT TTT
AAT TAT AAT G
[0435] where the BamHI endonuclease site is underlined and the
sequence of the light chain minus the start codon is in bold. The
inverse primer had the sequence:
TABLE-US-00011 (SEQ ID NO: 78) CCCCTGCAG tca TTT TTC TTG CCA TCC
ATG TTC TTC
[0436] where the PstI endonuclease site is underlined, the end of
the coding region of the heavy chain is in bold, and the stop codon
is in lower case. These primers were made using standard DNA
synthesis methodology.
[0437] The two primers were used in a PCR reaction containing
different amounts of Clostridium botulinum type E (strain beluga)
chromosomal DNA. The PCR reaction employed a DNA polymerase with
proofreading activity (Pfx DNA polymerase, obtained from Life
Technology) in order to avoid sequence errors in the amplified
gene. The amplification reaction conditions were as follows: 30
cycles of: a 45 second denaturation at 95.degree. C., followed by a
45 second annealing step at 56.degree. C., followed by a primer
extension reaction for 3 minutes 48 seconds at 68.degree. C.
[0438] The PCR product was digested with BamHI and HindIII, and the
digest subjected to agarose gel electrophoresis. Staining of the
agarose gel with ethidium bromide revealed a major DNA fragment of
approximately 3.5 kilobases (see FIG. 10). The band containing this
frangment was excised from the gel, and the DNA purified from the
agarose and ligated to BamHI and HindIII-cut pQE30 vector (Qiagen).
The resulting ligated plasmid was used to transform E. coli strain
JM 109 as described above, and the transformants plated onto
selective LB agar plates. Several clones were recovered and the
presence of the correct BoNT/E DNA insert checked by restriction
digest. The resultant construct contains the BoNT/E gene (minus the
first methionine) fused to the His.sub.6 tag of the pQE30 vector,
and contains 2 extra amino acid residues (glycine, serine), which
are contributed by the engineered BamHI site.
Example 10
Construction of a Proteolytically-Inactive Mutant of BoNT/E by Site
Directed Mutagenesis
[0439] By mutating the glutamic acid at position 212 (within the
active site) of the BoNT/E polypeptide construct to glutamine, a
proteolytically-inactive and non-toxic single-chain BoNT/E
polypeptide was obtained.
[0440] The glutamine replacement was introduced on the forward
primer using routine site directed mutagenesis methods. The
mutagenic DNA primer had the sequence cagTTAATACATTCATTA
CATGGACTATATG (SEQ ID NO: 79), where the codon encoding glutamine
at position 212 is indicated in small letters. An inverse PCR
reaction was performed using the above primer, along with the
reverse primer ATGCATTAATGTAAGAGCAGGATCTT (SEQ ID NO: 80) and Pfx
DNA polymerase (Life Technology) as above. The PCR template was the
wild-type single-chain BoNT/E construct (termed pQEESCwt). The
cycling parameters (30 cycles) were as follows: 1) a 45 second
denaturation step at 95.degree. C.; 2) a 45 second annealing step
at 56.degree. C.; and 3) a 7 minute 10 second extension step at
68.degree. C.
[0441] At the end of the amplification reaction, the DNA template
was digested by the restriction enzyme DpnI to permit selection of
mutated clones only. After subjecting the PCR product to agarose
gel electrophoresis, a band of approximately 7 kilobases was
removed and the DNA purified and used for self-ligation in the
presence of T4 DNA ligase (Promega) and polynucleotide kinase
(Promega) to permit phosphorylation of the PCR product. The
ligation mixture was used to transform E. coli strain DH10B, and
the transformants plated onto selective agar plates. The presence
of the correct plasmide construct was verified in several
representative transformants by restriction digest and the mutation
confirmed also by DNA sequencing. FIG. 11 shows the protocol for
construction of the mutant BoNT/E plasmid, and an ethidium
bromide-stained agarose gel of the PCR reaction mixture (lanes 2
and 3) versus molecular weight markers (lane 1).
Example 11
Purification of Single-Chain Recombinant BoNT/E
[0442] The presence of the histidine tag at the N-terminus of the
expressed protein allowed a single-step purification of the
recombinant neurotoxin by metal-affinity chromatography.
[0443] The E. coli strain M15 (Qiagen) was used for expression of
the BoNT/E single-chain construct. This strain carries an
endogenous plasmid (pREP4, kanamycin resistant) containing a region
encoding the lac I.sup.q repressor gene in order to prevent
transcription of the neurotoxin gene prior to induction with IPTG.
The pQE30 vector contain a T5 bacteriophage RNA polymerase
promoter, which is also recognized by E. coli RNA polymerase.
[0444] A colony of M15 cells containing pQEESCwt was grown at
37.degree. C. overnight in 5 ml of 2TY medium containing 0.1 mg/ml
ampicillin; 0.025 mg/ml kanamycin and 0.2% glucose (w/v), and the
resultant culture used to inoculate 500 ml of the same medium. When
this second culture reached an optical density of 0.5-0.8 at 600
nm, IPTG was added to a final concentration of 0.3 mM and the
culture incubated at 25.degree. C. overnight to permit expression
of the neurotoxin.
[0445] Subsequent centrifugation of the culture yielded .about.2.3
g of wet cell pellet which was resuspended in 10 ml of extraction
buffer (20 mM Hepes pH 7.0, 300 mM NaCl, 5 mM benzamidine, 2 .mu.M
pepstatin and 2 .mu.M E-64). Lysozyme was added to a final
concentration of 0.25 mg/ml, and the cell suspension incubated on
ice for 60 minutes. Approximately 0.5 ml of glass beads (0.1 mm
diameter from Biospec) was added to the cell suspension, followed
by vortexing for 2 minutes to break the cells. Cell-free extracts
was obtained by centrifugation at 10,000.times.g for 30 minutes at
4.degree. C. The supernatant was incubated with 0.5 ml of Talone
cobalt metal affinity resin (Clontech) pre-washed with extraction
buffer in a rocking platform for 45 minutes at 4.degree. C. The
resin was then loaded into a disposable chromatography column and
washed twice with 10 bed volumes of wash buffer (20 mM Hepes pH
7.0, 300 mM NaCl, 2 mM imidazole) before eluting the bound
neurotoxin in 6 bed volumes of elution buffer (20 mM Hepes pH 7.0,
300 mM NaCl, 150 mM imidazole).
[0446] The elute was dialyzed overnight at 4.degree. C. against 10
mM Hepes (pH 7.0) containing 150 mM NaCl and concentrated by
centrifugal filtration (MW cutoff 10 KDa) to a final concentration
of 1 mg/ml protein.
[0447] As shown in FIG. 12, the purity of the affinity-purified
toxin was demonstrated by SDS-PAGE under reducing conditions,
followed by Coomassie staining and Western-blotting, detecting the
N-terminus with a mouse monoclonal anti-His antibody from Quiagen
(diluted 2000 fold). Enhanced Chemiluminescence solutions (Santa
Cruz) and mouse secondary horseradish peroxidase (affinity purified
from Sigma) were used for detection of bound antibody.
Approximately 2 .mu.g of protein samples were loaded per well.
Example 12
Trypsin activation of Purified Recombinant BoNT/E Single-Chain
Polypeptide
[0448] Purified BoNT/E single-chain neurotoxin polypeptide samples
were activated by nicking the single-chain with trypsin (1.5
.mu.g/ml final concentration) for 60 minutes at a concentration of
1 mg toxin/ml in 10 mm Hepes (pH 7.0), 150 mM NaCl. Following the
reaction, the trypsin was inactivated using 0.5 mM PMSF and 10
.mu.g trypsin inhibitor/ml. The quality of the trypsinization was
assessed and verified by SDS-PAGE under both reducing and
non-reducing conditions, then staining with Coomassie staining and
Western blotting the polyacrylamide gel using a mouse monoclonal
anti-His antibody (Quiagen, diluted 2000-fold) and a mouse
monoclonal anti-H.sub.C IgG (diluted 26-fold). As shown in FIG. 13,
the Commassie-stained nicked protein resolves into two bands under
reducing conditions, while the heavy and light chains remain
disulfide-linked under non-reducing conditions, similar to the
native toxin. The antibody-detected recombinant heavy chain is of
approximately identical size as its wild-type Clostridium
counterpart, whereas the recombinant light chain migrates at a
slightly higher molecular weight compared to the native protein.
This latter characteristic is due to the extra residues provided by
the His.sub.6 tag at the N-terminus.
Example 13
Recombinant BoNT/E is Proteolytically Active
[0449] Stock solutions (1 .mu.M) of native nicked BoNT/E toxin,
un-nicked single-chain recombinant toxin, nicked di-chain
recombinant toxin, and nicked mutant (E212Q) BoNT/E were prepared
in HEPES-buffered saline (HBS, 150 mM NaCl, 10 mM HEPES, pH 7.4, 10
.mu.g/ml BSA). These samples were incubated for 30 minutes at
37.degree. C. in the absence or presence of 20 mM DTT, and then
serially diluted in 0.02 ml of HBS to the final concentrations
shown in FIG. 14.
[0450] A recombinant peptide containing amino acids 140-205 of
SNAP-25 fused to glutathione-S-transferase (termed GST-SNAP-25
[140-205]) was used as a protease substrate to test the proteolytic
activity of the recombinant BoNT/E polypeptides. Ten micrograms
this protease substrate was incubated with the toxin samples. The
digestion reaction was allowed to proceed for 30 minutes at
37.degree. C. in the absence or presence of 2 mM DTT, and stopped
by addition of SDS-PAGE sample buffer followed by boiling for 5
minutes.
[0451] The resultant samples were analyzed by SDS-PAGE (3 .mu.g of
GST-SNAP-25 [140-205] per lane) and silver staining. As FIG. 14
demonstrates, even unnicked recombinant single-chain toxin retains
proteolytic activity. As expected, the mutant E212Q BoNT/E
construct has no detectable proteolytic activity. FIG. 14 shows
only the GST-SNAP-25[140-205] bands.
Example 14
Nicking Makes Recombinant BoNT/E Fully Functional
[0452] Cerebellar neurons maintained for 10 days in culture
(2.times.10.sup.6/22 mm diameter well) were washed with
Krebs-Ringer HEPES (KRH) buffer, then exposed to the specified
concentrations of BoNT/E native ( ), trypsin-nicked recombinant
(.largecircle.), or un-nicked single-chain () BoNT/E. (See FIG.
15). After 60 minutes at 37.degree. C., the toxin-containing buffer
was removed and the cells were washed twice, then incubated with
KRH buffer containing 0.25 .mu.Ci/ml [.sup.14C]-labeled glutamine
(i.e. the glutamate precursor). After 45 minutes, the latter medium
was removed and the neurons were washed four times at 37.degree. C.
prior to assessment of transmitter glutamate release. Control and
toxin-treated neurons were incubated for 5 minutes at 37.degree. C.
in KRH buffer containing either 1.4 mM Ca.sup.2+ or 0.5 mM EGTA to
assess Ca.sup.2+-independent release; aliquots were then removed
for determination of their [.sup.14C]-glutamate content (see
below).
[0453] Immediately after removal of the basal medium, KRH buffer
containing 50 mM KCl and either 1.4 mM Ca.sup.2+ or 0.5 mM EGTA was
added; as before, aliquots were removed for [.sup.14C]-glutamate
assay after a 5 minute stimulation period. Finally, neurons were
solubilized with 20 mM EGTA.NaOH pH 7.5 containing 1% (w/v) SDS and
aliquots were removed to determine the amounts of radioactivity
remaining within the cells. The amount of [.sup.14C]-glutamate in
each of the samples was assayed by scintillation counting and the
levels released under basal and stimulated conditions were
expressed as percentages relative to the calculated total cell
content.
[0454] The percent [.sup.14C]-glutamate content in the
EGTA-containing buffer for each sample was subtracted from the
values recorded in Ca.sup.2+-containing KRH samples in order to
obtain the Ca.sup.2+-dependent component of release, and the latter
basal readings were subtracted from values obtained for 50 mM KCl
samples to yield K.sup.+-evoked Ca.sup.2+-dependent release. The
values, thus, obtained from toxin-treated neurons are expressed
relative to toxin-free controls.
[0455] FIG. 15 shows that, despite retaining proteolytic activity,
the un-nicked recombinant BoNT/E has markedly less activity than
either the native BoNT/E or the nicked recombinant version. This
finding may reflect the inability of the un-nicked toxin to
adequately enter the target cell. Additionally, the nicked
recombinant version appears to be more effective in inhibiting
glutamate release than the native toxin.
Example 15
Recombinant BoNT/E has a Neuromuscular Paralytic Activity
Equivalent to that of the Native Toxin at Mouse Neuromuscular
Endplates: Nicking Increases Potency
[0456] Mouse phrenic-nerve hemi-diaphragms were bathed in KR
supplemented with 0.1% BSA and saturated with 95% O.sub.2/5%
CO.sub.2. The phrenic nerves were stimulated (0.2 Hz, 1.5-2.5 mV)
and nerve evoked muscle tension was recorded before and after the
addition of (FIG. 16A) 0.2 nM recombinant nicked BoNT/E
(.largecircle.) or 0.2 nM native BoNT/E (.quadrature.), and (FIG.
16B) 1 nM recombinant un-nicked (.largecircle.), 1 nM recombinant
nicked (.largecircle.) or 0.05 nM recombinant nicked (.gradient.)
BoNT/E. As shown in FIGS. 6A and 16B, the recombinant nicked BoNT/E
is an effective paralytic agent, displaying greater activity in
this assay that the native toxin. The un-nicked toxin displays
significantly lower activity than the nicked toxin in this
assay.
[0457] The neuromuscular paralytic activity of recombinant nicked
BoNT/E was also demonstrated in mice by intra-muscular injection
into hind-limb muscles. This resulted in paralysis, as assessed by
the toe spread reflex assay, with a pattern of symptoms typical of
botulism.
[0458] The in vivo neurotoxicity of the nicked, recombinant
neurotoxin was established, by injecting the toxin into mice, to
have a specific neurotoxicity of less than 10.sup.7 mouse LD.sub.50
units per mg.
Example 16
The BoNT/E E212Q Protease Inactive Mutant Antagonises
BoNT/E-induced Neuroparalysis
[0459] A mouse phrenic-nerve hemi-diaphragm was exposed to 10 nM
BoNT/E E212Q in KR medium, the nerve was stimulated and evoked
muscle tension was recorded. As indicated by FIG. 17, the BoNT
E212Q mutant does not inhibit neurotransmission, as determined by
its failure to reduce nerve-evoked muscle tension (.largecircle.).
To assess the ability of this non-toxic mutant to antagonise the
activity of the native toxin, mouse phrenic-nerve hemi-diaphragms
were bathed for 60 minutes at 4.degree. C. in MKR supplemented with
0.1% BSA and saturated with 95% O.sub.2/5% CO.sub.2, without
(.gradient.) or with (.DELTA.) the inclusion of 5 nM BoNT/E E212Q.
Native nicked BoNT/E was added to each bath (0.05 nM final) and the
tissues were incubated for a further 30 min. The nerve-muscles were
then washed three times each with MKR followed by KR, before the
temperature was raised to 37.degree. C., the nerve stimulated and
evoked muscle tension recorded.
[0460] As shown in FIG. 17, the onset of native BoNT/E activity in
this assay was delayed and antagonized when the phrenic-nerve
hemi-diaphragms are preincubated with the E212Q protease inactive
mutant, thereby indicating that the recombinant mutant faithfully
binds to the same cell surface receptor as does the native toxin.
Thus, the methods of the present patent application can be used to
produce recombinant and modified toxins having fully functional
receptor binding domains, and BoNT-related transported molecules
for the intracellular delivery of therapeutic agents.
Example 17
Construction of an Activatable Clostridial Toxin Comprising an
Amino-Terminally Presented Binding Element
[0461] This example illustrates how to make an activatable
Clostridial toxin disclosed in the present specification comprising
a binding element located at the amino terminus of the modified
toxin.
17a. A binding element-translocation element-exogenous protease
cleavage site-therapeutic element organization.
[0462] A polynucleotide molecule based on BoNT/A-TEV-GDNFAP4A (SEQ
ID NO: 116) will be synthesized using standard procedures
(BlueHeron.RTM. Biotechnology, Bothell, Wash.). This polynucleotide
molecule encodes a BoNT/A modified to replace amino acids 872-1296
of SEQ ID NO: 1, a BoNT/A H.sub.C binding element, with amino acids
118-211 of SEQ ID NO: 81, a GDNF peptide, and to incorporate a TEV
protease site of SEQ ID NO: 24 within the di-chain loop region,
arranged in an amino to carboxyl linear organization as depicted in
FIG. 20A. The In addition, the altered binding element further
comprises at its amino terminus, a PAR 1 leader sequence ending in
an enterokinse cleavage site, which, upon cleavage, results in
exposing the first amino acid of the GDNF binding element.
Oligonucleotides of 20 to 50 bases in length are synthesized using
standard phosphoramidite synthesis. These oligonucleotides will be
hybridized into double stranded duplexes that are ligated together
to assemble the full-length polynucleotide molecule. This
polynucleotide molecule will be cloned using standard molecular
biology methods into a pUCBHB1 vector at the SmaI site to generate
pUCBHB1/BoNT/A-TEV-GDNFAP4A. The synthesized polynucleotide
molecule is verified by sequencing using Big Dye Terminator.TM.
Chemistry 3.1 (Applied Biosystems, Foster City, Calif.) and an ABI
3100 sequencer (Applied Biosystems, Foster City, Calif.).
[0463] If desired, an expression optimized polynucleotide molecule
based on BoNT/A-TEV-GDNFAP4A can be synthesized in order to improve
expression in an Escherichia coli strain. The polynucleotide
molecule encoding the BoNT/A-TEV-GDNFAP4A will be modified to 1)
contain synonymous codons typically present in native
polynucleotide molecules of an Escherichia coli strain; 2) contain
a G+C content that more closely matches the average G+C content of
native polynucleotide molecules found in an Escherichia coli
strain; 3) reduce polymononucleotide regions found within the
polynucleotide molecule; and/or 4) eliminate internal regulatory or
structural sites found within the polynucleotide molecule, see,
e.g., Lance E. Steward et al., Optimizing Expression of Active
Botulinum Toxin Type E, International Patent Publication WO
2006/011966 (Feb. 2, 2006); Lance E. Steward et al., Optimizing
Expression of Active Botulinum Toxin Type A, International Patent
Publication WO 2006/017749 (Feb. 16, 2006). Once sequence
optimization is complete, oligonucleotides of 20 to 50 bases in
length are synthesized using standard phosphoramidite synthesis.
These oligonucleotides are hybridized into double stranded duplexes
that are ligated together to assemble the full-length
polynucleotide molecule. This polynucleotide molecule is cloned
using standard molecular biology methods into a pUCBHB1 vector at
the SmaI site to generate pUCBHB1/BoNT/A-TEV-GDNFAP4A. The
synthesized polynucleotide molecule is verified by sequencing using
Big Dye Terminator.TM. Chemistry 3.1 (Applied Biosystems, Foster
City, Calif.) and an ABI 3100 sequencer (Applied Biosystems, Foster
City, Calif.). If so desired, expression optimization to a
different organism, such as, e.g., a yeast strain, an insect
cell-line or a mammalian cell line, can be done, see, e.g.,
Steward, supra, (Feb. 2, 2006); and Steward, supra, (Feb. 16,
2006).
[0464] A similar cloning strategy will be used to make pUCBHB1

[0467] To construct pET29/BoNT/A-TEV-GDNFAP4A, a
pUCBHB1/BoNT/A-TEV-GDNFAP4A construct will be digested with
restriction endonucleases that 1) will excise the polynucleotide
molecule encoding the open reading frame of BoNT/A-TEV-GDNFAP4A;
and 2) will enable this polynucleotide molecule to be
operably-linked to a pET29 vector (EMD Biosciences-Novagen,
Madison, Wis.). This insert will be subcloned using a T4 DNA ligase
procedure into a pET29 vector that is digested with appropriate
restriction endonucleases to yield pET29/BoNT/A-TEV-GDNFAP4A. The
ligation mixture will be transformed into chemically competent E.
coli DH5.alpha. cells (Invitrogen, Inc, Carlsbad, Calif.) using a
heat shock method, will be plated on 1.5% Luria-Bertani agar plates
(pH 7.0) containing 50 .mu.g/mL of Kanamycin, and will be placed in
a 37.degree. C. incubator for overnight growth. Bacteria containing
expression constructs will be identified as Kanamycin resistant
colonies. Candidate constructs will be isolated using an alkaline
lysis plasmid mini-preparation procedure and will be analyzed by
restriction endonuclease digest mapping to determine the presence
and orientation of the insert. This cloning strategy will yield a
pET29 expression construct comprising the polynucleotide molecule
encoding the BoNT/A-TEV-GDNFAP4A operably-linked to a carboxyl
terminal polyhistidine affinity binding peptide.
[0468] A similar cloning strategy will be used to make pET29

starter culture will be used to inoculate a 3 L baffled flask
containing ZYP-5052 autoinducing media containing 50 .mu.g/mL of
Kanamycin at a dilution of 1:1000. Culture volumes will range from
about 600 mL (20% flask volume) to about 750 mL (25% flask volume).
These cultures will be grown in a 37.degree. C. incubator shaking
at 250 rpm for approximately 5.5 hours and will be then transferred
to a 16.degree. C. incubator shaking at 250 rpm for overnight
expression. Cells will be harvested by centrifugation (4,000 rpm at
4.degree. C. for 20-30 minutes) and will be used immediately, or
will be stored dry at -80.degree. C. until needed.
Example 21
Purification and Quantification of Activatable Clostridial
Toxins
[0509] The following example illustrates methods useful for
purification and quantification of any activatable Clostridial
toxins disclosed in the present specification.
[0510] For immobilized metal affinity chromatography (IMAC) protein
purification, E. coli BL21 (DE3) cell pellets used to express a
modified Clostridial toxin, as described in Example 20, will be
resuspended in Column Binding Buffer (25 mM N-(2-hydroxyethyl)
piperazine-N'-(2-ethanesulfonic acid) (HEPES), pH 7.8; 500 mM
sodium chloride; 10 mM imidazole; 2.times. Protease Inhibitor
Cocktail Set III (EMD Biosciences-Calbiochem, San Diego Calif.); 5
units/mL of Benzonase (EMD Biosciences-Novagen, Madison, Wis.);
0.1% (v/v) TRITON-X.RTM. 100, 4-octylphenol polyethoxylate; 10%
(v/v) glycerol), and will then be transferred to a cold Oakridge
centrifuge tube. The cell suspension will be sonicated on ice
(10-12 pulses of 10 seconds at 40% amplitude with 60 seconds
cooling intervals on a Branson Digital Sonifier) in order to lyse
the cells and then is centrifuged (16,000 rpm at 4.degree. C. for
20 minutes) to clarify the lysate. An immobilized metal affinity
chromatography column will be prepared using a 20 mL Econo-Pac
column support (Bio-Rad Laboratories, Hercules, Calif.) packed with
2.5-5.0 mL of TALON.TM. SuperFlow Co2+affinity resin (BD
Biosciences-Clontech, Palo Alto, Calif.), which will then be
equilibrated by rinsing with 5 column volumes of deionized,
distilled water, followed by 5 column volumes of Column Binding
Buffer. The clarified lysate will be applied slowly to the
equilibrated column by gravity flow (approximately 0.25-0.3
mL/minute). The column will then be washed with 5 column volumes of
Column Wash Buffer (N-(2-hydroxyethyl)
piperazine-N'-(2-ethanesulfonic acid) (HEPES), pH 7.8; 500 mM
sodium chloride; 10 mM imidazole; 0.1% (v/v) Triton-X.RTM. 100,
4-octylphenol polyethoxylate; 10% (v/v) glycerol). The modified
Clostridial toxin will be eluted with 20-30 mL of Column Elution
Buffer (25 mM N-(2-hydroxyethyl) piperazine-N'-(2-ethanesulfonic
acid) (HEPES), pH 7.8; 500 mM sodium chloride; 500 mM imidazole;
0.1% (v/v) TRITON-X.RTM. 100, 4-octylphenol polyethoxylate; 10%
(v/v) glycerol) and will be collected in approximately twelve 1 mL
fractions. The amount of modified Clostridial toxin contained in
each elution fraction will be determined by a Bradford dye assay.
In this procedure, 20 .mu.L aliquots of each 1.0 mL fraction will
be combined with 200 .mu.L of Bio-Rad Protein Reagent (Bio-Rad
Laboratories, Hercules, Calif.), diluted 1 to 4 with deionized,
distilled water, and then the intensity of the colorimetric signal
will be measured using a spectrophotometer. The five fractions with
the strongest signal will be considered the elution peak and will
be combined together. Total protein yield will be determined by
estimating the total protein concentration of the pooled peak
elution fractions using bovine gamma globulin as a standard
(Bio-Rad Laboratories, Hercules, Calif.).
[0511] For purification of a modified Clostridial toxin using a
FPLC desalting column, a HiPrep.TM. 26/10 size exclusion column
(Amersham Biosciences, Piscataway, N.J.) will be pre-equilibrated
with 80 mL of 4.degree. C. Column Buffer (50 mM sodium phosphate,
pH 6.5). After the column is equilibrated, a modified Clostridial
toxin sample will be applied to the size exclusion column with an
isocratic mobile phase of 4.degree. C. Column Buffer and at a flow
rate of 10 mL/minute using a BioLogic DuoFlow chromatography system
(Bio-Rad Laboratories, Hercules, Calif.). The desalted modified
Clostridial toxin sample will be collected as a single fraction of
approximately 7-12 mL.
[0512] For purification of a modified Clostridial toxin using a
FPLC ion exchange column, a modified Clostridial toxin sample that
has been desalted following elution from an IMAC column will be
applied to a 1 mL Q1.TM. anion exchange column (Bio-Rad
Laboratories, Hercules, Calif.) using a BioLogic DuoFlow
chromatography system (Bio-Rad Laboratories, Hercules, Calif.). The
sample will be applied to the column in 4.degree. C. Column Buffer
(50 mM sodium phosphate, pH 6.5) and will be eluted by linear
gradient with 4.degree. C. Elution Buffer (50 mM sodium phosphate,
1 M sodium chloride, pH 6.5) as follows: step 1, 5.0 mL of 5%
Elution Buffer at a flow rate of 1 mL/minute; step 2, 20.0 mL of
5-30% Elution Buffer at a flow rate of 1 mL/minute; step 3, 2.0 mL
of 50% Elution Buffer at a flow rate of 1.0 mL/minute; step 4, 4.0
mL of 100% Elution Buffer at a flow rate of 1.0 mL/minute; and step
5, 5.0 mL of 0% Elution Buffer at a flow rate of 1.0 mL/minute.
Elution of modified Clostridial toxin from the column will be
monitored at 280, 260, and 214 nm, and peaks absorbing above a
minimum threshold (0.01 au) at 280 nm will be collected. Most of
the modified Clostridial toxin will be eluted at a sodium chloride
concentration of approximately 100 to 200 mM. Average total yields
of modified Clostridial toxin will be determined by a Bradford
assay.
[0513] Expression of a modified Clostridial toxin will be analyzed
by polyacrylamide gel electrophoresis. Samples purified using the
procedure described above are added to 2.times.LDS Sample Buffer
(Invitrogen, Inc, Carlsbad, Calif.) and will be separated by MOPS
polyacrylamide gel electrophoresis using NuPAGE.RTM. Novex 4-12%
Bis-Tris precast polyacrylamide gels (Invitrogen, Inc, Carlsbad,
Calif.) under denaturing, reducing conditions. Gels will be stained
with SYPRO.RTM. Ruby (Bio-Rad Laboratories, Hercules, Calif.) and
the separated polypeptides will be imaged using a Fluor-S MAX
Multilmager (Bio-Rad Laboratories, Hercules, Calif.) for
quantification of modified Clostridial toxin expression levels. The
size and amount of modified Clostridial toxin will be determined by
comparison to MagicMark.TM. protein molecular weight standards
(Invitrogen, Inc, Carlsbad, Calif.).
[0514] Expression of modified Clostridial toxin will also be
analyzed by Western blot analysis. Protein samples purified using
the procedure described above will be added to 2.times.LDS Sample
Buffer (Invitrogen, Inc, Carlsbad, Calif.) and will be separated by
MOPS polyacrylamide gel electrophoresis using NuPAGE.RTM. Novex
4-12% Bis-Tris precast polyacrylamide gels (Invitrogen, Inc,
Carlsbad, Calif.) under denaturing, reducing conditions. Separated
polypeptides will be transferred from the gel onto polyvinylidene
fluoride (PVDF) membranes (Invitrogen, Inc, Carlsbad, Calif.) by
Western blotting using a Trans-Blot.RTM. SD semi-dry
electrophoretic transfer cell apparatus (Bio-Rad Laboratories,
Hercules, Calif.). PVDF membranes will be blocked by incubating at
room temperature for 2 hours in a solution containing 25 mM
Tris-Buffered Saline (25 mM 2-amino-2-hydroxymethyl-1,3-propanediol
hydrochloric acid (Tris-HCl)(pH 7.4), 137 mM sodium chloride, 2.7
mM potassium chloride), 0.1% TWEEN-20.RTM., polyoxyethylene (20)
sorbitan monolaureate, 2% bovine serum albumin, 5% nonfat dry milk.
Blocked membranes will be incubated at 4.degree. C. for overnight
in Tris-Buffered Saline TWEEN-20.RTM. (25 mM Tris-Buffered Saline,
0.1% TWEEN-20.RTM., polyoxyethylene (20) sorbitan monolaureate)
containing appropriate primary antibodies as a probe. Primary
antibody probed blots will be washed three times for 15 minutes
each time in Tris-Buffered Saline TWEEN-20.RTM.. Washed membranes
will be incubated at room temperature for 2 hours in Tris-Buffered
Saline TWEEN-20.RTM. containing an appropriate immunoglobulin G
antibody conjugated to horseradish peroxidase as a secondary
antibody. Secondary antibody-probed blots will be washed three
times for 15 minutes each time in Tris-Buffered Saline
TWEEN-20.RTM.. Signal detection of the labeled modified Clostridial
toxin will be visualized using the ECL Plus.TM. Western Blot
Detection System (Amersham Biosciences, Piscataway, N.J.) and will
be imaged with a Typhoon 9410 Variable Mode Imager (Amersham
Biosciences, Piscataway, N.J.) for quantification of modified
Clostridial toxin expression levels.
