FIELD OF THE INVENTION
[0002] The present invention relates to a variant of parent
Termamyl-like alpha-amylase, which variant has alpha-amylase
activity and exhibits an alteration in at least one of the
following properties relative to said parent alpha-amylase:
[0003] Substrate specificity, substrate binding, substrate cleavage
pattern, thermal stability, pH activity profile, pH stability
profile, stability towards oxidation, Ca.sup.2+ dependency, reduced
and increased pI and improved wash performance, specific activity,
stability under, e.g., high temperature and/or low pH conditions,
in particular at low calcium concentrations. The variant of the
invention are suitable for starch conversion, ethanol production,
laundry wash, dish wash, hard surface cleaning, textile desizing,
and/or sweetener production.
BACKGROUND OF THE INVENTION
[0004] Alpha-Amylases (alpha-1,4-glucan-4-glucanohydrolases, E.C.
3.2.1.1) constitute a group of enzymes, which catalyze hydrolysis
of starch and other linear and branched 1,4-glucosidic oligo- and
polysaccharides.
BRIEF DISCLOSURE OF THE INVENTION
[0005] The object of the present invention is to provide a
Termamyl-like alpha-amylase, which variant in comparison to the
corresponding parent alpha-amylase, i.e., un-mutated alpha-amylase,
has alpha-amylase activity and exhibits an alteration in at least
one of the above mentioned properties relative to said parent
alpha-amylase.
Nomenclature
[0006] In the present description and claims, the conventional
one-letter and three-letter codes for amino acid residues are used.
For ease of reference, alpha-amylase variants of the invention are
described by use of the following nomenclature:
Original amino acid(s): position(s): substituted amino acid(s)
[0007] According to this nomenclature, for instance the
substitution of alanine for asparagine in position 30 is shown
as:
[0008] Ala30Asn or A30N
a deletion of alanine in the same position is shown as:
[0009] Ala30* or A30*
and insertion of an additional amino acid residue, such as lysine,
is shown as:
[0010] Ala30AlaLys or A30AK
[0011] A deletion of a consecutive stretch of amino acid residues,
such as amino acid residues 30-33, is indicated as (30-33)* or
.DELTA.(A30-N33).
[0012] Where a specific alpha-amylase contains a "deletion" in
comparison with other alpha-amylases and an insertion is made in
such a position this is indicated as:
[0013] *36Asp or *36D
for insertion of an aspartic acid in position 36.
[0014] Multiple mutations are separated by plus signs, i.e.:
[0015] Ala30Asp+Glu34Ser or A30N+E34S
representing mutations in positions 30 and 34 substituting alanine
and glutamic acid for asparagine and serine, respectively.
[0016] When one or more alternative amino acid residues may be
inserted in a given position it is indicated as
[0017] A30N,E or
[0018] A30N or A30E
[0019] Furthermore, when a position suitable for modification is
identified herein without any specific modification being
suggested, it is to be understood that any amino acid residue may
be substituted for the amino acid residue present in the position.
Thus, for instance, when a modification of an alanine in position
30 is mentioned, but not specified, it is to be understood that the
alanine may be deleted or substituted for any other amino acid,
i.e., any one of:
R,N,D,A,C,Q,E,G,H,I,L,K,M,F,P,S,T,W,Y,V.
[0020] Further, "A30X" means any one of the following
substitutions: A30R, A30N, A30D, A30C, A30Q, A30E, A30G, A30H,
A301, A30L, A30K, A30M, A30F, A30P, A30S, A30T, A30W, A30Y, or A30
V; or in short: A30R,N,D,C,Q,E,G,H,I,L,K,M,F,P,S,T,W,Y,V.
[0021] If the parent enzyme--used for the numbering--already has
the amino acid residue in question suggested for substitution in
that position the following nomenclature is used: [0022] "X30N" or
"X30N,V" in the case where for instance one or N or V is present in
the wildtype.
[0023] Thus, it means that other corresponding parent enzymes are
substituted to an "Asn" or "Val" in position 30.
Characteristics of Amino Acid Residues
Charged Amino Acids:
Asp, Glu, Arg, Lys, His
[0024] Negatively Charged Amino Acids (with the Most Negative
Residue First):
Asp, Glu
[0025] Positively Charged Amino Acids (with the Most Positive
Residue First):
Arg, Lys, His
Neutral Amino Acids:
Gly, Ala, Val, Leu, Ile, Phe, Tyr, Trp, Met, Cys, Asn, Gln, Ser,
Thr, Pro
[0026] Hydrophobic Amino Acid Residues (with the Most Hydrophobic
Residue Listed Last):
Gly, Ala, Val, Pro, Met, Leu, Ile, Tyr, Phe, Trp,
[0027] Hydrophilic Amino Acids (with the Most Hydrophilic Residue
Listed Last):
Thr, Ser, Cys, Gln, Asn
BRIEF DESCRIPTION OF THE DRAWINGS
[0028] FIG. 1 is an alignment of the amino acid sequences of five
parent Termamyl-like alpha-amylases. The numbers on the extreme
left designate the respective amino acid sequences as follows:
[0029] 1: SEQ ID NO: 4 (SP722)
[0030] 2: SEQ ID NO: 2 (SP690)
[0031] 3: SEQ ID NO: 10 (BAN)
[0032] 4: SEQ ID NO: 8 (BLA)
[0033] 5: SEQ ID NO: 6 (BSG).
DETAILED DISCLOSURE OF THE INVENTION
[0034] The object of the present invention is to provide a
Termamyl-like amylase, which variant has alpha-amylase activity and
exhibits an alteration in at least one of the following properties
relative to the parent alpha-amylase: substrate specificity,
substrate binding, substrate cleavage pattern, thermal stability,
pH activity profile, pH stability profile, stability towards
oxidation, Ca.sup.2+ dependency, specific activity, stability
under, e.g., high temperature and/or low pH conditions, in
particular at low calcium concentrations.
Termamyl-Like Alpha-Amylases
[0035] A number of alpha-amylases produced by Bacillus spp. are
highly homologous (identical) on the amino acid level.
[0036] The identity of a number of known Bacillus alpha-amylases
can be found in the below Table 1:
TABLE-US-00001 TABLE 1 Percent identity 707 AP1378 BAN BSG SP690
SP722 AA560 Termamyl 707 100.0 86.4 66.9 66.5 87.6 86.2 95.5 68.1
AP1378 86.4 100.0 67.1 68.1 95.1 86.6 86.0 69.4 BAN 66.9 67.1 100.0
65.6 67.1 68.8 66.9 80.7 BSG 66.5 68.1 65.6 100.0 67.9 67.1 66.3
65.4 SP690 87.6 95.1 67.1 67.9 100.0 87.2 87.0 69.2 SP722 86.2 86.6
68.8 67.1 87.2 100.0 86.8 70.8 AA560 95.5 86.0 66.9 66.3 87.0 86.8
100.0 68.3 Termamyl 68.1 69.4 80.7 65.4 69.2 70.8 68.3 100.0
[0037] For instance, the B. licheniformis alpha-amylase (BLA)
comprising the amino acid sequence shown in SEQ ID NO: 8
(commercially available as Termamyl.TM.) has been found to be about
81% homologous with the B. amyloliquefaciens alpha-amylase
comprising the amino acid sequence shown in SEQ ID NO: 10 and about
65% homologous with the B. stearothermophilus alpha-amylase (BSG)
comprising the amino acid sequence shown in SEQ ID NO: 6. Further
homologous alpha-amylases include SP690 and SP722 disclosed in WO
95/26397 and further depicted in SEQ ID NO: 2 and SEQ ID NO: 4,
respectively, herein. Other amylases are the AA560 alpha-amylase
derived from Bacillus sp. and shown in SEQ ID NO: 12, and the #707
alpha-amylase derived from Bacillus sp., shown in SEQ ID NO: 13 and
described by Tsukamoto et al., Biochemical and Biophysical Research
Communications, 151 (1988), pp. 25-31.
[0038] The KSM AP1378 alpha-amylase is disclosed in WO 97/00324
(from KAO Corporation).
[0039] Still further homologous alpha-amylases include the
alpha-amylase produced by the B. licheniformis strain described in
EP 0252666 (ATCC 27811), and the alpha-amylases identified in WO
91/00353 and WO 94/18314. Other commercial Termamyl-like
alpha-amylases are comprised in the products sold under the
following tradenames: Optitherm.TM. and Takatherm.TM. (Solvay);
Maxamyl.TM. (available from Gist-brocades/Genencor), Spezym AA.TM.
and Spezyme Delta AA.TM. (available from Genencor), and
Keistase.TM. (available from Daiwa), Dex Io, GC 521 (available from
Genencor) and Ultraphlow (from Enzyme Biosystems).
[0040] Because of the substantial homology found between these
alpha-amylases, they are considered to belong to the same class of
alpha-amylases, namely the class of "Termamyl-like
alpha-amylases".
[0041] Accordingly, in the present context, the term
"Termamyl-like" alpha-amylase" is intended to indicate an
alpha-amylase, in particular Bacillus alpha-amylase, especially
Bacillus licheniformis alpha-amylase, which, at the amino acid
level, exhibits a substantial identity to Termamyl.TM., i.e., the
B. licheniformis alpha-amylase having the amino acid sequence shown
in SEQ ID NO: 8, herein.
[0042] In other words, all the following alpha-amylases, which has
the amino acid sequences shown in SEQ ID NOS: 2, 4, 6, 8, 10, 12
and 13 herein are considered to be "Termamyl-like alpha-amylase".
Other Termamyl-like alpha-amylases are alpha-amylases i) which
displays at least 60%, such as at least 70%, e.g., at least 75%, or
at least 80%, at least 85%, at least 90%, at least 95%, at least
96%, at least 97%, at least 98%, at least 99% homology (identity)
with at least one of said amino acid sequences shown in SEQ ID NOS:
2, 4, 6, 8, 10, 12, and 13, and/or is encoded by a DNA sequence
which hybridizes to the DNA sequences encoding the above-specified
alpha-amylases which are apparent from SEQ ID NOS: 1, 3, 5, 7, 9,
and of the present specification (which encoding sequences encode
the amino acid sequences shown in SEQ ID NOS: 2, 4, 6, 8, 10 and 12
herein, respectively).
Homology (Identity)
[0043] The homology may be determined as the degree of identity
between the two sequences indicating a derivation of the first
sequence from the second. The homology may suitably be determined
by means of computer programs known in the art such as GAP provided
in the GCG program package (described above). Thus, Gap GCGv8 may
be used with the default scoring matrix for identity and the
following default parameters: GAP creation penalty of 5.0 and GAP
extension penalty of 0.3, respectively for nucleic acidic sequence
comparison, and GAP creation penalty of 3.0 and GAP extension
penalty of 0.1, respectively, for protein sequence comparison. GAP
uses the method of Needleman and Wunsch, (1970), J. Mol. Biol. 48,
p. 443-453, to make alignments and to calculate the identity.
[0044] A structural alignment between Termamyl (SEQ ID NO: 8) and,
e.g., another alpha-amylase may be used to identify
equiva-lent/corresponding positions in other Termamyl-like
alpha-amylases. One method of obtaining said structural alignment
is to use the Pile Up programme from the GCG package using default
values of gap penalties, i.e., a gap creation penalty of 3.0 and
gap extension penalty of 0.1. Other structural alignment methods
include the hydrophobic cluster analysis (Gaboriaud et al., (1987),
FEBS LETTERS 224, pp. 149-155) and reverse threading (Huber, T;
Torda, A E, PROTEIN SCIENCE Vol. 7, No. 1 pp. 142-149 (1998).
Hybridisation
[0045] The oligonucleotide probe used in the characterisation of
the Termamyl-like alpha-amylase above may suitably be prepared on
the basis of the full or partial nucleotide or amino acid sequence
of the alpha-amylase in question.
[0046] Suitable conditions for testing hybridisation involve
pre-soaking in 5.times.SSC and prehybridizing for 1 hour at
40.degree. C. in a solution of 20% formamide, 5.times.Denhardt's
solution, 50 mM sodium phosphate, pH 6.8, and 50 mg of denatured
sonicated calf thymus DNA, followed by hybridisation in the same
solution supplemented with 100 mM ATP for 18 hours at 40.degree.
C., followed by three times washing of the filter in 2.times.SSC,
0.2% SDS at 40.degree. C. for 30 minutes (low stringency),
preferred at 50.degree. C. (medium stringency), more preferably at
65.degree. C. (high stringency), even more preferably at 75.degree.
C. (very high stringency). More details about the hybridisation
method can be found in Sambrook et al., Molecular Cloning: A
Laboratory Manual, 2nd Ed., Cold Spring Harbor, 1989.
[0047] In the present context, "derived from" is intended not only
to indicate an alpha-amylase produced or producible by a strain of
the organism in question, but also an alpha-amylase encoded by a
DNA sequence isolated from such strain and produced in a host
organism trans-formed with said DNA sequence. Finally, the term is
intended to indicate an alpha-amylase, which is encoded by a DNA
sequence of synthetic and/or cDNA origin and which has the
identifying characteristics of the alpha-amylase in question. The
term is also intended to indicate that the parent alpha-amylase may
be a variant of a naturally occurring alpha-amylase, i.e., a
variant, which is the result of a modification (insertion,
substitution, deletion) of one or more amino acid residues of the
naturally occurring alpha-amylase.
Parent Termamyl-Like Alpha-Amylases
[0048] According to the invention any Termamy-like alpha-amylase,
as defined above, may be used as the parent (i.e., backbone)
alpha-amylase. In a preferred embodiment of the invention the
parent alpha-amylase is derived from B. licheniformis, e.g., one of
those referred to above, such as the B. licheniformis alpha-amylase
having the amino acid sequence shown in SEQ ID NO: 8.
Parent Hybrid Termamyl-Like Alpha-Amylases
[0049] The parent alpha-amylase (i.e., backbone alpha-amylase) may
also be a hybrid alpha-amylase, i.e., an alpha-amylase, which
comprises a combination of partial amino acid sequences derived
from at least two alpha-amylases.
[0050] The parent hybrid alpha-amylase may be one, which on the
basis of amino acid homology (identity) and/or DNA hybridization
(as defined above) can be determined to belong to the Termamyl-like
alpha-amylase family. In this case, the hybrid alpha-amylase is
typically composed of at least one part of a Termamyl-like
alpha-amylase and part(s) of one or more other alpha-amylases
selected from Termamyl-like alpha-amylases or non-Termamyl-like
alpha-amylases of microbial (bacterial or fungal) and/or mammalian
origin.
[0051] Thus, the parent hybrid alpha-amylase may comprise a
combination of partial amino acid sequences deriving from at least
two Termamyl-like alpha-amylases, or from at least one
Termamyl-like and at least one non-Termamyl-like bacterial
alpha-amylase, or from at least one Termamyl-like and at least one
fungal alpha-amylase. The Termamyl-like alpha-amylase from which a
partial amino acid sequence derives, may be any of the specific
Termamyl-like alpha-amylase referred to herein.
[0052] For instance, the parent alpha-amylase may comprise a
C-terminal part of an alpha-amylase derived from a strain of B.
licheniformis, and a N-terminal part of an alpha-amylase derived
from a strain of B. amyloliquefaciens or from a strain of B.
stearothermophilus (BSG). For instance, the parent alpha-amylase
may comprise at least 430 amino acid residues of the C-terminal
part of the B. licheniformis alpha-amylase, and may, e.g., comprise
a) an amino acid segment corresponding to the 37 N-terminal amino
acid residues of the B. amyloliquefaciens alpha-amylase having the
amino acid sequence shown in SEQ ID NO: 10 and an amino acid
segment corresponding to the 445 C-terminal amino acid residues of
the B. licheniformis alpha-amylase having the amino acid sequence
shown in SEQ ID NO: 8, or a hybrid Termamyl-like alpha-amylase
being identical to the Termamyl sequence, i.e., the Bacillus
licheniformis alpha-amylase shown in SEQ ID NO: 8, except that the
N-terminal 35 amino acid residues (of the mature protein) has been
replaced by the N-terminal 33 residues of BAN (mature protein),
i.e., the Bacillus amyloliquefaciens alpha-amylase shown in SEQ ID
NO: 10; or b) an amino acid segment corresponding to the 68
N-terminal amino acid residues of the B. stearothermophilus
alpha-amylase having the amino acid sequence shown in SEQ ID NO: 6
and an amino acid segment corresponding to the 415 C-terminal amino
acid residues of the B. licheniformis alpha-amylase having the
amino acid sequence shown in SEQ ID NO: 8.
[0053] Another suitable parent hybrid alpha-amylase is the one
previously described in WO 96/23874 (from Novo Nordisk)
constituting the N-terminus of BAN, Bacillus amyloliquefaciens
alpha-amylase (amino acids 1-300 of the mature protein) and the

[0091] Variants of the invention may have altered oxidation
stability, in particular higher oxidation stability, in comparison
to the parent alpha-amylase. Increased oxidation stability is
advantageous in, e.g., detergent compositions and descresed
oxidation stability may be advantageous in composition for starch
liquefaction. Oxidation stability may be determined as described in
the "Material & Methods" section below.
Altered pH Profile
[0092] Important positions and mutations with respect to obtaining
variants with altered pH profile, in particular improved activity
at especially high pH (i.e., pH 8-10.5) or low pH (i.e., pH 4-6)
include mutations of amino residues located close to the active
site residues.
[0093] Preferred specific mutations/substitutions are the ones
listed above in the section "Altered Properties" for the positions
in question. Suitable assays are described in the "Materials &
Methods" section below.
Wash Performance
[0094] Important positions and mutations with respect to obtaining
variants with improved wash performance at especially high pH
(i.e., pH 8.5-11) include the specific mutations/substitutions
listed above in the section "Altered Properties" for the positions
in question. The wash performance may be tested as described below
in the "Materials & Methods" section.
Increased pI
Substitutions Resulting in Higher pI
[0095] In an aspect the invention relates to a variant with a
higher pI than the parent alpha-amylase. Such variants are suitable
when adjusting the pI to the washing conditions of various
detergents. This means that if the pI of the parent alpha-amylase
is below the pH in the washing solution the target is to increase
the pI to the pH of the washing solution. Such variant may be
prepared by making the following kind of substitutions:
1) Substituting one or more of the below mentioned negatively
charged amino acid residue in a parent alpha-amylase with a
positively charged amino acid residue. 2) Substituting one or more
of the below mentioned neutral amino acid residue in a parent
alpha-amylase with a positively charged amino acid residue; 3)
Substituting one or more of the below mentioned negatively charged
amino acid residue in a parent alpha-amylase with a neutral amino
acid residue; 4) Substituting one or more of the below mentioned
positively charged amino acid residue in a parent alpha-amylase
with a more positively charged amino acid residue;
[0096] Variants of the invention with increased pI in comparison to
the parent alpha-amylase may have improved wash performance. Wash
performance tests may be carried out as described in the "Materials
& Method" section.

Decreased pI
Substitutions Resulting in Lower pI
[0098] Variants of the invention with decreased pI in comparison to
the parent alpha-amylase may have improved liquefying effect. This
means that the pI of the parent amylase should be adjusted to the
pH conditions in the liquefying process in question. Normally the
pH during liquefaction lies in the range of 4-7, such as between pH
4.5-6.5. An example of a liquefaction process is descripted below
in the section "Liquefaction". Improved liquefying effect may be
carried out as described in the "Materials & Method"
section.
[0099] Alternatively, variants with decreased pI may advantageously
be used in detergent. If the pI of the parent alpha-amylase is
above the pH in the washing solution the target is to decrease the
pI to the pH of the washing solution. Such variant may be prepared
by making the following kind of substitutions:
1) Substituting one or more of the below mentioned positively
charged amino acid residue in a parent alpha-amylase with a neutral
amino acid residue. 2) Substituting one or more of the below
mentioned neutral amino acid residue in a parent alpha-amylase with
a negatively charged amino acid residue. 3) Substituting one or
more of the below mentioned positively charged amino acid residue
with a negatively charged amino acid residue. 4) Substituting one
or more of the below mentioned negatively charged amino acid
residue with a more negatively charged amino acid residue.

Reduced Sensitivity to Anionic Surfactants
Substitutions Resulting in a More Hydrophilic Amino Acid
Residue
[0101] In an aspect, the invention relates to providing
alpha-amylase variants with reduced sensitivity (or improved
stability against denaturation) to anionic surfactants (in
particular linear alkyl sulphonates (LAS)). These variants are
provided by substituting, deleting or inserting an amino acid
residue in the parent alpha-amylase as indicated below with a more
hydrophilic amino acid residue. Such variants may be prepared
by:
1) Substituting one or more of the below mentioned positively
charged amino acid residue in a parent alpha-amylase with a
hydrophilic amino acid residue. 2) Substituting one or more of the
below mentioned hydrophobic amino acid residue in a parent
alpha-amylase with a hydrophilic amino acid residue 3) Substituting
one or more of the below mentioned positively charged amino acid
residue in a parent alpha-amylase with a neutral or negatively
charged amino acid residue.
[0102] The anionic surfactants (in particular linear alkyl
sulphonates (LAS)) sensitivity (in detergent) may be tested as
described in the "Materials & Methods" section.
[0103] Variants of the invention with reduced sensitivity to
anionic surfactants, in particular linear alkyl sulphonates (LAS),
include (using the Bacillus licheniformis alpha-amylase shown in
SEQ ID NO: 8 numbering):

[0104] Increased Stability at Low pH and/or at High Temperature
Substitutions Resulting in a More Hydrophobic Amino Acid
Residue
[0105] In an aspect the invention relates to Termamyl-like
alpha-amylase variant with increased stability at acidic pH and/or
at high temperature in comparison to the parent alpha-amylase. Such
variants are especially suitable for starch liquefaction.
[0106] In the context of the invention the term "acidic pH" means a
pH below 7.0, especially below the pH range, in which industrial
starch liquefaction processes are normally performed, which is
between pH 5.5 and 6.2.
[0107] In the context of the invention "high temperature" is a
temperature in the range from 60-110.degree. C. Such variant are
variant having a substitution resulting in a more hydrophobic amino
acid residues. Providing such variant of the invention may be
prepared by
1) Substituting a charged amino acid residue with a hydrophobic
amino acid residue; 2) Substituting a hydrophilic amino acid
residue with a hydrophobic amino acid residue; 3) Substituting a
hydrophilic amino acid residue with a more hydrophilic amino acid
residue; 4) Substituting a hydrophilic amino acid residue with a
less hydrophilic amino acid residue.
[0108] Thus, variants of the invention include (using SEQ ID NO: 8

General Mutations in Variants of the Invention
[0109] A variant of the invention may in one embodiment comprise
one or more modifications in addition to those outlined above.
Thus, it may be advantageous that one or more Proline (Pro)
residues present in the part of the alpha-amylase variant which is
modified is/are replaced with a non-Proline residue which may be
any of the possible, naturally occurring non-Proline residues, and
which preferably is an Alanine, Glycine, Serine, Threonine, Valine
or Leucine.
[0110] Analogously, in one embodiment one or more Cysteine residues
present in the parent alpha-amylase may be replaced with a
non-Cysteine residue such as Serine, Alanine, Threonine, Glycine,
Valine or Leucine.
[0111] Furthermore, a variant of the invention may--either as the
only modification or in combination with any of the above outlined
modifications--be modified so that one or more Asp and/or Glu
present in an amino acid fragment corresponding to the amino acid
fragment 185-209 of SEQ ID NO: 10 is replaced by an Asn and/or Gln,
respectively. Also of interest is the replacement, in the
Termamyl-like alpha-amylase, of one or more of the Lys residues
present in an amino acid fragment corresponding to the amino acid
fragment 185-209 of SEQ ID NO: 10 by an Arg.
[0112] It is to be understood that the present invention
encompasses variants incorporating two or more of the above
outlined modifications.
[0113] Furthermore, it may be advantageous to introduce mutations
in one or more of the following positions (using SEQ ID NO: 8
(Termamyl) for the numbering):
M15, V128, A111, H133, W138, T149, M197, N188, A209, A210, H405,
T412, in particular the following single, double or triple or multi
mutations: M15X, in particular M15T,L; V128X, in particular V128E;
H133X, in particular H133Y; N188X, in particular N188S,T,P; M197X,
in particular M197T,L; A209X, in particular A209V;
M197T/W138F; M197T/W138Y; M15T/H133Y/N188S;
M15N128E/H133Y/N1885; E119C/S130C; D124C/R127c; H133Y/T1491;
G475R, H133Y/S187D; H133Y/A209V.
Methods for Preparing Alpha-Amylase Variants of the Invention
[0114] Several methods for introducing mutations into genes are
known in the art. After a brief description of cloning of
alpha-amylase-encoding DNA sequences, methods for generating
mutations at specific sites within the alpha-amylase-encoding
sequence will be described.
Cloning a DNA Sequence Encoding an Alpha-Amylase
[0115] The DNA sequence encoding a parent alpha-amylase may be
isolated from any cell or microorganism producing the alpha-amylase
in question, using various methods well known in the art. First, a
genomic DNA and/or cDNA library should be constructed using
chromosomal DNA or messenger RNA from the organism that produces
the alpha-amylase to be studied. Then, if the amino acid sequence
of the alpha-amylase is known, homologous, labeled oligonucleotide
probes may be synthesized and used to identify
alpha-amylase-encoding clones from a genomic library prepared from
the organism in question. Alternatively, a labeled oligonucleotide
probe containing sequences homologous to a known alpha-amylase gene
could be used as a probe to identify alpha-amylase-encoding clones,
using hybridization and washing conditions of lower stringency.
[0116] Yet another method for identifying alpha-amylase-encoding
clones would involve inserting fragments of genomic DNA into an
expression vector, such as a plasmid, transforming
alpha-amylase-negative bacteria with the resulting genomic DNA
library, and then plating the transformed bacteria onto agar
containing a substrate for alpha-amylase, thereby allowing clones
expressing the alpha-amylase to be identified.
[0117] Alternatively, the DNA sequence encoding the enzyme may be
prepared synthetically by established standard methods, e.g., the
phosphoroamidite method described by S. L. Beaucage and M. H.
Caruthers, Tetrahedron Letters 22, 1981, pp. 1859-1869, or the
method described by Matthes et al., The EMBO J. 3, 1984, pp.
801-805. In the phosphoroamidite method, oligonucleotides are
synthesized, e.g., in an automatic DNA synthesizer, purified,
annealed, ligated and cloned in appropriate vectors.
[0118] Finally, the DNA sequence may be of mixed genomic and
synthetic origin, mixed synthetic and cDNA origin or mixed genomic
and cDNA origin, prepared by ligating fragments of synthetic,
genomic or cDNA origin (as appropriate, the fragments corresponding
to various parts of the entire DNA sequence), in accordance with
standard techniques. The DNA sequence may also be prepared by
polymerase chain reaction (PCR) using specific primers, for
instance as described in U.S. Pat. No. 4,683,202 or R. K. Saiki et
al., Science 239, 1988, pp. 487-491.
Site-Directed Mutagenesis
[0119] Once an alpha-amylase-encoding DNA sequence has been
isolated, and desirable sites for mutation identified, mutations
may be introduced using synthetic oligonucleotides. These
oligonucleotides contain nucleotide sequences flanking the desired
mutation sites; mutant nucleotides are inserted during
oligonucleotide synthesis. In a specific method, a single-stranded
gap of DNA, bridging the alpha-amylase-encoding sequence, is
created in a vector carrying the alpha-amylase gene. Then the
synthetic nucleotide, bearing the desired mutation, is annealed to
a homologous portion of the single-stranded DNA. The remaining gap
is then filled in with DNA polymerase I (Klenow fragment) and the
construct is ligated using T4 ligase. A specific example of this
method is described in Morinaga et al. (1984). U.S. Pat. No.
4,760,025 disclose the introduction of oligonucleotides encoding
multiple mutations by performing minor alterations of the cassette.
However, an even greater variety of mutations can be introduced at
any one time by the Morinaga method, because a multitude of
oligonucleotides, of various lengths, can be introduced.
[0120] Another method for introducing mutations into
alpha-amylase-encoding DNA sequences is described in Nelson and
Long (1989). It involves the 3-step generation of a PCR fragment
containing the desired mutation introduced by using a chemically
synthesized DNA strand as one of the primers in the PCR reactions.
From the PCR-generated fragment, a DNA fragment carrying the
mutation may be isolated by cleavage with restriction endonucleases
and reinserted into an expression plasmid.
[0121] Alternative methods for providing variants of the invention
include gene shuffling, e.g., as described in WO 95/22625 (from
Affymax Technologies N.V.) or in WO 96/00343 (from Novo Nordisk
A/S), or other corresponding techniques resulting in a hybrid
enzyme comprising the mutation(s), e.g., substitution(s) and/or
deletion(s), in question.
Expression of Alpha-Amylase Variants
[0122] According to the invention, a DNA sequence encoding the
variant produced by methods described above, or by any alternative
methods known in the art, can be expressed, in enzyme form, using
an expression vector which typically includes control sequences
encoding a promoter, operator, ribosome binding site, translation
initiation signal, and, optionally, a repressor gene or various
activator genes.
[0123] The recombinant expression vector carrying the DNA sequence
encoding an alpha-amylase variant of the invention may be any
vector, which may conveniently be subjected to recombinant DNA
procedures, and the choice of vector will often depend on the host
cell into which it is to be introduced. Thus, the vector may be an
autonomously replicating vector, i.e., a vector which exists as an
extrachromosomal entity, the replication of which is independent of
chromosomal replication, e.g., a plasmid, a bacteriophage or an
extrachromosomal element, minichromosome or an artificial
chromosome. Alternatively, the vector may be one which, when
introduced into a host cell, is integrated into the host cell
genome and replicated together with the chromosome(s) into which it
has been integrated.
[0124] In the vector, the DNA sequence should be operably connected
to a suitable promoter sequence. The promoter may be any DNA
sequence, which shows transcriptional activity in the host cell of
choice and may be derived from genes encoding proteins either
homologous or heterologous to the host cell. Examples of suitable
promoters for directing the transcription of the DNA sequence
encoding an alpha-amylase variant of the invention, especially in a
bacterial host, are the promoter of the lac operon of E. coli, the
Streptomyces coelicolor agarase gene dagA promoters, the promoters
of the Bacillus licheniformis alpha-amylase gene (amyL), the
promoters of the Bacillus stearothermophilus maltogenic amylase
gene (amyM), the promoters of the Bacillus amyloliquefaciens
alpha-amylase (amyQ), the promoters of the Bacillus subtilis xylA
and xylB genes etc. For transcription in a fungal host, examples of
useful promoters are those derived from the gene encoding A. oryzae
TAKA amylase, Rhizomucor miehei aspartic proteinase, A. niger
neutral alpha-amylase, A. niger acid stable alpha-amylase, A. niger
glucoamylase, Rhizomucor miehei lipase, A. oryzae alkaline
protease, A. oryzae triose phosphate isomerase or A. nidulans
acetamidase.
[0125] The expression vector of the invention may also comprise a
suitable transcription terminator and, in eukaryotes,
polyadenylation sequences operably connected to the DNA sequence
encoding the alpha-amylase variant of the invention. Termination
and polyadenylation sequences may suitably be derived from the same
sources as the promoter.
[0126] The vector may further comprise a DNA sequence enabling the
vector to replicate in the host cell in question. Examples of such
sequences are the origins of replication of plasmids pUC19,
pACYC177, pUB110, pE194, pAMB1 and pIJ702.
[0127] The vector may also comprise a selectable marker, e.g. a
gene the product of which complements a defect in the host cell,
such as the dal genes from B. subtilis or B. licheniformis, or one
which confers antibiotic resistance such as ampicillin, kanamycin,
chloramphenicol or tetracyclin resistance. Furthermore, the vector
may comprise Aspergillus selection markers such as amdS, argB, niaD
and sC, a marker giving rise to hygromycin resistance, or the
selection may be accomplished by co-transformation, e.g., as
described in WO 91/17243.
[0128] While intracellular expression may be advantageous in some
respects, e.g., when using certain bacteria as host cells, it is
generally preferred that the expression is extracellular. In
general, the Bacillus alpha-amylases mentioned herein comprise a
preregion permitting secretion of the expressed protease into the
culture medium. If desirable, this preregion may be replaced by a
different preregion or signal sequence, conveniently accomplished
by substitution of the DNA sequences encoding the respective
preregions.
[0129] The procedures used to ligate the DNA construct of the
invention encoding an alpha-amylase variant, the promoter,
terminator and other elements, respectively, and to insert them
into suitable vectors containing the information necessary for
replication, are well known to persons skilled in the art (cf., for
instance, Sambrook et al., Molecular Cloning: A Laboratory Manual,
2nd Ed., Cold Spring Harbor, 1989).
[0130] The cell of the invention, either comprising a DNA construct
or an expression vector of the invention as defined above, is
advantageously used as a host cell in the recombinant production of
an alpha-amylase variant of the invention. The cell may be
transformed with the DNA construct of the invention encoding the
variant, conveniently by integrating the DNA construct (in one or
more copies) in the host chromosome. This integration is generally
considered to be an advantage as the DNA sequence is more likely to
be stably maintained in the cell. Integration of the DNA constructs
into the host chromosome may be performed according to conventional
methods, e.g., by homologous or heterologous recombination.
Alternatively, the cell may be transformed with an expression
vector as described above in connection with the different types of
host cells.
[0131] The cell of the invention may be a cell of a higher organism
such as a mammal or an insect, but is preferably a microbial cell,
e.g., a bacterial or a fungal (including yeast) cell.
[0132] Examples of suitable bacteria are Gram-positive bacteria
such as Bacillus subtilis, Bacillus licheniformis, Bacillus lentus,
Bacillus brevis, Bacillus stearothermophilus, Bacillus
alkalophilus, Bacillus amyloliquefaciens, Bacillus coagulans,
Bacillus circulans, Bacillus lautus, Bacillus megaterium, Bacillus
thuringiensis, or Streptomyces lividans or Streptomyces murinus, or
gram-negative bacteria such as E. coli. The transformation of the
bacteria may, for instance, be effected by protoplast
transformation or by using competent cells in a manner known per
se.
[0133] The yeast organism may favorably be selected from a species
of Saccharomyces or Schizosaccharomyces, e.g. Saccharomyces
cerevisiae. The filamentous fungus may advantageously belong to a
species of Aspergillus, e.g., Aspergillus oryzae or Aspergillus
niger. Fungal cells may be transformed by a process involving
protoplast formation and transformation of the protoplasts followed
by regeneration of the cell wall in a manner known per se. A
suitable procedure for transformation of Aspergillus host cells is
described in EP 238 023.
[0134] In a yet further aspect, the present invention relates to a
method of producing an alpha-amylase variant of the invention,
which method comprises cultivating a host cell as described above
under conditions conducive to the production of the variant and
recovering the variant from the cells and/or culture medium.
[0135] The medium used to cultivate the cells may be any
conventional medium suitable for growing the host cell in question
and obtaining expression of the alpha-amylase variant of the
invention. Suitable media are available from commercial suppliers
or may be prepared according to published recipes (e.g., as
described in catalogues of the American Type Culture
Collection).
[0136] The alpha-amylase variant secreted from the host cells may
conveniently be recovered from the culture medium by well-known
procedures, including separating the cells from the medium by
centrifugation or filtration, and precipitating proteinaceous
components of the medium by means of a salt such as ammonium
sulphate, followed by the use of chromatographic procedures such as
ion exchange chromatography, affinity chromatography, or the
like.
INDUSTRIAL APPLICATIONS
[0137] The alpha-amylase variants of this invention possess
valuable properties allowing for a variety of industrial
applications. In particular, enzyme variants of the invention are
applicable as a component in washing, dishwashing, and hard surface
cleaning detergent compositions.
[0138] Variant of the invention with altered properties may be used
for starch processes, in particular starch conversion, especially
liquefaction of starch (see, e.g., U.S. Pat. No. 3,912,590, EP
patent application nos. 252 730 and 63 909, WO 99/19467, and WO
96/28567 all references hereby incorporated by reference). Also
contemplated are compositions for starch conversion purposes, which
may beside the variant of the invention also comprise a
glucoamylase, pullulanase, and other alpha-amylases.
[0139] Further, variants of the invention are also particularly
useful in the production of sweeteners and ethanol (see, e.g., U.S.
Pat. No. 5,231,017 hereby incorporated by reference), such as fuel,
drinking and industrial ethanol, from starch or whole grains.
[0140] Variants of the invention may also be useful for desizing of
textiles, fabrics and garments (see, e.g., WO 95/21247, U.S. Pat.
No. 4,643,736, EP 119,920 hereby in corporate by reference), beer
making or brewing, in pulp and paper production.
Starch Conversion
[0141] Conventional starch-conversion processes, such as
liquefaction and saccharification processes are described, e.g., in
U.S. Pat. No. 3,912,590 and EP patent publications Nos. 252,730 and
63,909, hereby incorporated by reference.
[0142] In an embodiment the starch conversion process degrading
starch to lower molecular weight carbohydrate components such as
sugars or fat replacers includes a debranching step.
Starch to Sugar Conversion
[0143] In the case of converting starch into a sugar the starch is
depolymerized. A such depolymerization process consists of a
Pre-treatment step and two or three consecutive process steps, viz.
a liquefaction process, a saccharification process and dependent on
the desired end product optionally an isomerization process.
Pre-Treatment of Native Starch
[0144] Native starch consists of microscopic granules, which are
insoluble in water at room temperature. When an aqueous starch
slurry is heated, the granules swell and eventually burst,
dispersing the starch molecules into the solution. During this
"gelatinization" process there is a dramatic increase in viscosity.
As the solids level is 30-40% in a typically industrial process,
the starch has to be thinned or "liquefied" so that it can be
handled. This reduction in viscosity is today mostly obtained by
enzymatic degradation.
Liquefaction
[0145] During the liquefaction step, the long chained starch is
degraded into branched and linear shorter units (maltodextrins) by
an alpha-amylase. The liquefaction process is carried out at
105-110.degree. C. for 5 to 10 minutes followed by 1-2 hours at
95.degree. C. The pH lies between 5.5 and 6.2. In order to ensure
optimal enzyme stability under these conditions, 1 mM of calcium is
added (40 ppm free calcium ions). After this treatment the
liquefied starch will have a "dextrose equivalent" (DE) of
10-15.
Saccharification
[0146] After the liquefaction process the maltodextrins are
converted into dextrose by addition of a glucoamylase (e.g., AMG)
and a debranching enzyme, such as an isoamylase (U.S. Pat. No.
4,335,208) or a pullulanase (e.g., Promozyme.TM.) (U.S. Pat. No.
4,560,651). Before this step the pH is reduced to a value below
4.5, maintaining the high temperature (above 95.degree. C.) to
inactivate the liquefying alpha-amylase to reduce the formation of
short oligosaccharide called "panose precursors" which cannot be
hydrolyzed properly by the debranching enzyme.
[0147] The temperature is lowered to 60.degree. C., and
glucoamylase and debranching enzyme are added. The saccharification
process proceeds for 24-72 hours.
[0148] Normally, when denaturing the .alpha.-amylase after the
liquefaction step about 0.2-0.5% of the saccharification product is
the branched trisaccharide 6.sup.2-alpha-glucosyl maltose (panose)
which cannot be degraded by a pullulanase. If active amylase from
the liquefaction step is present during saccharification (i.e., no
denaturing), this level can be as high as 1-2%, which is highly
undesirable as it lowers the saccharification yield
significantly.
Isomerization
[0149] When the desired final sugar product is, e.g., high fructose
syrup the dextrose syrup may be converted into fructose. After the
saccharification process the pH is increased to a value in the
range of 6-8, preferably pH 7.5, and the calcium is removed by ion
exchange. The dextrose syrup is then converted into high fructose
syrup using, e.g., an immobilized glucoseisomerase (such as
Sweetzyme.TM. IT).
Ethanol Production
[0150] In general alcohol production (ethanol) from whole grain can
be separated into 4 main steps
[0151] Milling
[0152] Liquefaction
[0153] Saccharification
[0154] Fermentation
Milling
[0155] The grain is milled in order to open up the structure and
allowing for further processing. Two processes are used wet or dry
milling. In dry milling the whole kernel is milled and used in the
remaining part of the process. Wet milling gives a very good
separation of germ and meal (starch granules and protein) and is
with a few exceptions applied at locations where there is a
parallel production of syrups.
Liquefaction
[0156] In the liquefaction process the starch granules are
solubilized by hydrolysis to maltodextrins mostly of a DP higher
than 4. The hydrolysis may be carried out by acid treatment or
enzymatically by alpha-amylase. Acid hydrolysis is used on a
limited basis. The raw material can be milled whole grain or a side
stream from starch processing.
[0157] Enzymatic liquefaction is typically carried out as a
three-step hot slurry process. The slurry is heated to between
60-95.degree. C., preferably 80-85.degree. C., and the enzyme(s) is
(are) added. Then the slurry is jet-cooked at between
95-140.degree. C., preferably 105-125.degree. C., cooled to
60-95.degree. C. and more enzyme(s) is (are) added to obtain the
final hydrolysis. The liquefaction process is carried out at pH
4.5-6.5, typically at a pH between 5 and 6. Milled and liquefied
grain is also known as mash.
Saccharification
[0158] To produce low molecular sugars DP.sub.1-3 that can be
metabolized by yeast, the maltodextrin from the liquefaction must
be further hydrolyzed. The hydrolysis is typically done
enzymatically by glucoamylases, alternatively alpha-glucosidases or
acid alpha-amylases can be used. A full saccharification step may
last up to 72 hours, however, it is common only to do a
pre-saccharification of typically 40-90 minutes and then complete
saccharification during fermentation (SSF). Saccharification is
typically carried out at temperatures from 30-65.degree. C.,
typically around 60.degree. C., and at pH 4.5.
Fermentation
[0159] Yeast typically from Saccharomyces spp. is added to the mash
and the fermentation is ongoing for 24-96 hours, such as typically
35-60 hours. The temperature is between 26-34.degree. C., typically
at about 32.degree. C., and the pH is from pH 3-6, preferably
around pH 4-5.
[0160] Note that the most widely used process is a simultaneous
saccharification and fermentation (SSF) process where there is no
holding stage for the saccharification, meaning that yeast and
enzyme is added together. When doing SSF it is common to introduce
a pre-saccharification step at a temperature above 50.degree. C.,
just prior to the fermentation.
Distillation
[0161] Following the fermentation the mash is distilled to extract
the ethanol.
[0162] The ethanol obtained according to the process of the
invention may be used as, e.g., fuel ethanol; drinking ethanol,
i.e., potable neutral spirits; or industrial ethanol.
By-products
[0163] Left over from the fermentation is the grain, which is
typically used for animal feed either in liquid form or dried.
[0164] Further details on how to carry out liquefaction,
saccharification, fermentation, distillation, and recovering of
ethanol are well known to the skilled person.
[0165] According to the process of the invention the
saccharification and fermentation may be carried out simultaneously
or separately.
Pulp and Paper Production
[0166] The alkaline alpha-amylase of the invention may also be used
in the production of lignocellulosic materials, such as pulp, paper
and cardboard, from starch reinforced waste paper and cardboard,
especially where re-pulping occurs at pH above 7 and where amylases
facilitate the disintegration of the waste material through
degradation of the reinforcing starch. The alpha-amylase of the
invention is especially useful in a process for producing a
papermaking pulp from starch-coated printed-paper. The process may
be performed as described in WO 95/14807, comprising the following
steps:
[0167] a) disintegrating the paper to produce a pulp,
[0168] b) treating with a starch-degrading enzyme before, during or
after step a), and
c) separating ink particles from the pulp after steps a) and
b).
[0169] The alpha-amylases of the invention may also be very useful
in modifying starch where enzymatically modified starch is used in
papermaking together with alkaline fillers such as calcium
carbonate, kaolin and clays. With the alkaline alpha-amylases of
the invention it becomes possible to modify the starch in the
presence of the filler thus allowing for a simpler integrated
process.
Desizing of Textiles, Fabrics and Garments
[0170] An alpha-amylase of the invention may also be very useful in
textile, fabric or garment desizing. In the textile processing
industry, alpha-amylases are traditionally used as auxiliaries in
the desizing process to facilitate the removal of starch-containing
size, which has served as a protective coating on weft yarns during
weaving. Complete removal of the size coating after weaving is
important to ensure optimum results in the subsequent processes, in
which the fabric is scoured, bleached and dyed. Enzymatic starch
breakdown is preferred because it does not involve any harmful
effect on the fiber material. In order to reduce processing cost
and increase mill throughput, the desizing processing is sometimes
combined with the scouring and bleaching steps. In such cases,
non-enzymatic auxiliaries such as alkali or oxidation agents are
typically used to break down the starch, because traditional
alpha-amylases are not very compatible with high pH levels and
bleaching agents. The non-enzymatic breakdown of the starch size
does lead to some fiber damage because of the rather aggressive
chemicals used. Accordingly, it would be desirable to use the
alpha-amylases of the invention as they have an improved
performance in alkaline solutions. The alpha-amylases may be used
alone or in combination with a cellulase when desizing
cellulose-containing fabric or textile.
[0171] Desizing and bleaching processes are well known in the art.
For instance, such processes are described in WO 95/21247, U.S.
Pat. No. 4,643,736, EP 119,920 hereby in corporate by reference.
Commercially available products for desizing include AQUAZYME.RTM.
and AQUAZYME.RTM. ULTRA from Novozymes A/S.
Beer Making
[0172] The alpha-amylases of the invention may also be very useful
in a beer-making process; the alpha-amylases will typically be
added during the mashing process.
Detergent Compositions
[0173] The alpha-amylase of the invention may be added to and thus
become a component of a detergent composition.
[0174] The detergent composition of the invention may for example
be formulated as a hand or machine laundry detergent composition
including a laundry additive composition suitable for pre-treatment
of stained fabrics and a rinse added fabric softener composition,
or be formulated as a detergent composition for use in general
household hard surface cleaning operations, or be formulated for
hand or machine dishwashing operations.
[0175] In a specific aspect, the invention provides a detergent
additive comprising the enzyme of the invention. The detergent
additive as well as the detergent composition may comprise one or
more other enzymes such as a protease, a lipase, a peroxidase,
another amylolytic enzyme, e.g., another alpha-amylase,
glucoamylase, maltogenic amylase, CGTase and/or a cellulase,
mannanase (such as MANNAWAY.TM. from Novozymes, Denmark)),
pectinase, pectine lyase, cutinase, and/or laccase.
[0176] In general the properties of the chosen enzyme(s) should be
compatible with the selected detergent, (i.e., pH-optimum,
compatibility with other enzymatic and non-enzymatic ingredients,
etc.), and the enzyme(s) should be present in effective
amounts.

comprise a H.sub.2O.sub.2 source such as perborate or percarbonate
which may be combined with a peracid-forming bleach activator such
as tetraacetylethylenediamine or nonanoyloxybenzenesulfonate.
Alternatively, the bleaching system may comprise peroxyacids of,
e.g., the amide, imide, or sulfone type.
[0199] The enzyme(s) of the detergent composition of the invention
may be stabilized using conventional stabilizing agents, e.g., a
polyol such as propylene glycol or glycerol, a sugar or sugar
alcohol, lactic acid, boric acid, or a boric acid derivative, e.g.,
an aromatic borate ester, or a phenyl boronic acid derivative such
as 4-formylphenyl boronic acid, and the composition may be

Filter Screening Assays
[0230] The below assays can be used to screening of Termamyl-like
alpha-amylase variants having altered stability at high or low pH
and/or under Ca.sup.2+ depleted conditions compared to the parent
enzyme and Termamyl-like alpha-amylase.
High pH Filter Assay
[0231] Bacillus libraries are plated on a sandwich of cellulose
acetate (OE 67, Schleicher & Schuell, Dassel, Germany)--and
nitrocellulose filters (Protran-Ba 85, Schleicher & Schuell,
Dassel, Germany) on TY agar plates with 10 micro g/ml kanamycin at
37.degree. C. for at least 21 hours. The cellulose acetate layer is
located on the TY agar plate.
[0232] Each filter sandwich is specifically marked with a needle
after plating, but before incubation in order to be able to
localize positive variants on the filter and the nitrocellulose
filter with bound variants is transferred to a container with
glycin-NaOH buffer, pH 8.6-10.6 and incubated at room temperature
(can be altered from 10-60.degree. C.) for 15 min. The cellulose
acetate filters with colonies are stored on the TY-plates at room
temperature until use. After incubation, residual activity is
detected on plates containing 1% agarose, 0.2% starch in
glycin-NaOH buffer, pH 8.6-10.6. The assay plates with
nitrocellulose filters are marked the same way as the filter
sandwich and incubated for 2 hours at room temperature. After
removal of the filters the assay plates are stained with 10% Lugol
solution. Starch degrading variants are detected as white spots on
dark blue background and then identified on the storage plates.
Positive variants are rescreened twice under the same conditions as
the first screen.
Low Calcium Filter Assay
[0233] Bacillus libraries are plated on a sandwich of cellulose
acetate (OE 67, Schleicher & Schuell, Dassel, Germany)--and
nitrocellulose filters (Protran-Ba 85, Schleicher & Schuell,
Dassel, Germany) on TY agar plates with a relevant antibiotic,
e.g., kanamycin or chloramphenicol, at 37.degree. C. for at least
21 hours. The cellulose acetate layer is located on the TY agar
plate. Each filter sandwich is specifically marked with a needle
after plating, but before incubation in order to be able to
localize positive variants on the filter and the nitrocellulose
filter with bound variants is transferred to a container with
carbonate/bicarbonate buffer pH 8.5-10 and with different EDTA
concentrations (0.001 mM-100 mM). The filters are incubated at room
temperature for 1 hour. The cellulose acetate filters with colonies
are stored on the TY-plates at room temperature until use. After
incubation, residual activity is detected on plates containing 1%
agarose, 0.2% starch in carbonate/bicarbonate buffer pH 8.5-10. The
assay plates with nitrocellulose filters are marked the same way as
the filter sandwich and incubated for 2 hours at room temperature.
After removal of the filters the assay plates are stained with 10%
Lugol solution. Starch degrading variants are detected as white
spots on dark blue background and then identified on the storage
plates. Positive variants are rescreened twice under the same
conditions as the first screen.
Low pH Filter Assay
[0234] Bacillus libraries are plated on a sandwich of cellulose
acetate (OE 67, Schleicher & Schuell, Dassel, Germany)--and
nitrocellulose filters (Protran-Ba 85, Schleicher & Schuell,
Dassel, Germany) on TY agar plates with 10 micro g/ml
chloramphenicol at 37.degree. C. for at least 21 hours. The
cellulose acetate layer is located on the TY agar plate.
[0235] Each filter sandwich is specifically marked with a needle
after plating, but before incubation in order to be able to
localize positive variants on the filter, and the nitrocellulose
filter with bound variants is transferred to a container with
citrate buffer, pH 4.5 and incubated at 80.degree. C. for 20
minutes (when screening for variants in the wild type backbone) or
85.degree. C. for 60 minutes (when screening for variants of the
parent alpha-amylase). The cellulose acetate filters with colonies
are stored on the TY-plates at room temperature until use. After
incubation, residual activity is detected on assay plates
containing 1% agarose, 0.2% starch in citrate buffer, pH 6.0. The
assay plates with nitrocellulose filters are marked the same way as
the filter sandwich and incubated for 2 hours at 50.degree. C.
After removal of the filters the assay plates are stained with 10%
Lugol solution. Starch degrading variants are detected as white
spots on dark blue background and then identified on the storage
plates. Positive variants are re-screened twice under the same
conditions as the first screen.
Secondary Screening
[0236] Positive transformants after rescreening are picked from the
storage plate and tested in a secondary plate assay. Positive
transformants are grown for 22 hours at 37.degree. C. in 5 ml
LB+chloramphenicol. The Bacillus culture of each positive
transformant and as a control a clone expressing the corresponding
backbone are incubated in citrate buffer, pH 4.5 at 90.degree. C.
and samples are taken at 0, 10, 20, 30, 40, 60 and 80 minutes. A 3
micro liter sample is spotted on an assay plate. The assay plate is
stained with 10% Lugol solution. Improved variants are seen as
variants with higher residual activity (detected as halos on the
assay plate) than the backbone. The improved variants are
determined by nucleotide sequencing.
Stability Assay of Unpurified Variants:
[0237] Bacillus cultures expressing the variants to be analysed are
grown for 21 hours at 37.degree. C. in 10 ml LB+chloramphenicol.
800 micro liter culture is mixed with 200 micro l citrate buffer,
pH 4.5. A number of 70 micro l aliquots corresponding to the number
of sample time points are made in PCR tubes and incubated at
70.degree. C. or 90.degree. C. for various time points (typically
5, 10, 15, 20, 25 and 30 minutes) in a PCR machine. The 0 min
sample is not incubated at high temperature. Activity in the sample
is measured by transferring 20 micro 1 to 200 micro l of the
alpha-amylase PNP-G.sub.7 substrate MPR3 ((Boehringer Mannheim Cat.
no. 1660730) as described below under "Assays for Alpha-Amylase
Activity". Results are plotted as percentage activity (relative to
the 0 time point) versus time, or stated as percentage residual
activity after incubation for a certain period of time.
Fermentation and Purification of Alpha-Amylase Variants
[0238] A B. subtilis strain harbouring the relevant expression
plasmid is streaked on a LB-agar plate with 10 micro g/ml kanamycin
from -80.degree. C. stock, and grown overnight at 37.degree. C. The
colonies are transferred to 100 ml PS-1 media supplemented with 10
micro g/ml chloamphinicol in a 500 ml shaking flask.
Composition of PS-1 Medium:
TABLE-US-00013 [0239] Pearl sugar 100 g/l Soy Bean Meal 40 g/l
Na.sub.2HPO.sub.4, 12H.sub.2O 10 g/l Pluronic .TM. PE 6100 0.1 g/l
CaCO.sub.3 5 g/l
[0240] The culture is shaken at 37.degree. C. at 270 rpm for 5
days.
[0241] Cells and cell debris are removed from the fermentation
broth by centrifugation at 4500 rpm in 20-25 minutes. Afterwards
the supernatant is filtered to obtain a completely clear solution.
The filtrate is concentrated and washed on a UF-filter (10000 cut
off membrane) and the buffer is changed to 20 mM Acetate pH 5.5.
The UF-filtrate is applied on a S-sepharose F.F. and elution is
carried out by step elution with 0.2M NaCl in the same buffer. The
eluate is dialysed against 10 mM Tris, pH 9.0 and applied on a
Q-sepharose F.F. and eluted with a linear gradient from 0-0.3M NaCl
over 6 column volumes. The fractions that contain the activity
(measured by the Phadebas assay) are pooled, pH was adjusted to pH
7.5 and remaining color was removed by a treatment with 0.5% W/vol.
active coal in 5 minutes.
Stability Determination of Purified Variants
[0242] All stability trials of purified variants are made using the
same set up. The method is as follows: The enzyme is incubated
under the relevant conditions (1-4). Samples are taken at various
time points, e.g., after 0, 5, 10, 15 and 30 minutes and diluted 25
times (same dilution for all taken samples) in assay buffer (0.1M
50 mM Britton buffer pH 7.3) and the activity is measured using the
Phadebas assay (Pharmacia) under standard conditions pH 7.3,
37.degree. C.
[0243] The activity measured before incubation (0 minutes) is used
as reference (100%). The decline in percent is calculated as a
function of the incubation time. The table shows the residual
activity after, e.g., 30 minutes of incubation.
Specific Activity Determination
[0244] The specific activity is determined using the Phadebas.RTM.
assay (Pharmacia) as activity/mg enzyme. The manufactures
instructions are followed (see also below under "Assay for
Alpha-Amylase Activity).
Determination of Isoelectric Point
[0245] The pI is determined by isoelectric focusing (ex: Pharmacia,
Ampholine, pH 3.5-9.3).
Stability Determination
[0246] The amylase stability is measured using the method as
follows:
[0247] The enzyme is incubated under the relevant conditions.
Samples are taken at various time points, e.g., after 0, 5, 10, 15
and 30 minutes and diluted 25 times (same dilution for all taken
samples) in assay buffer (0.1M 50 mM Britton buffer pH 7.3) and the
activity is measured using the Phadebas assay (Pharmacia) under
standard conditions pH 7.3, 37.degree. C.
[0248] The activity measured before incubation (0 minutes) is used
as reference (100%). The decline in percent is calculated as a
function of the incubation time. The table shows the residual
activity after, e.g., 30 minutes of incubation.
Measurement of the Calcium- and pH-Dependent Stability
[0249] Normally industrial liquefaction processes runs using pH
6.0-6.2 as liquefaction pH and an addition of 40 ppm free calcium
in order to improve the stability at 95.degree. C.-105.degree. C.
Some of the herein proposed substitutions have been made in order
to improve the stability at
1. lower pH than pH 6.2 and/or 2. at free calcium levels lower than
40 ppm free calcium.
[0250] Two different methods can be used to measure the alterations
in stability obtained by the different substitutions in the
alpha-amylase in question:
[0251] Method 1
[0252] One assay which measures the stability at reduced pH, pH
5.0, in the presence of 5 ppm free calcium.
[0253] 10 micro g of the variant are incubated under the following
conditions: A 0.1 M acetate solution, pH adjusted to pH 5.0,
containing 5 ppm calcium and 5% w/w common corn starch (free of
calcium). Incubation is made in a water bath at 95.degree. C. for
30 minutes.
[0254] Method 2
[0255] One assay, which measure the stability in the absence of
free calcium and where the pH is maintained at pH 6.0. This assay
measures the decrease in calcium sensitivity: 10 micro g of the
variant were incubated under the following conditions: A 0.1 M
acetate solution, pH adjusted to pH 6.0, containing 5% w/w common
corn starch (free of calcium). Incubation was made in a water bath
at 95.degree. C. for 30 minutes.
Oxidation Stability Determination
[0256] Raw filtered culture broths with different variants of the
invention are diluted to an amylase activity of 100 KNU/ml (defined
above) in 50 mM of a Britton-Robinson buffer at pH 9.0 and
incubated at 40.degree. C. Subsequently H.sub.2O.sub.2 is added to
a concentration of 200 mM, and the pH value is re-adjusted to 9.0.
The activity is now measured after 15 seconds and after 5, 15, and
30 minutes. The absorbance of the resulting blue solution, measured
spectrophotometrically at 620 nm, is a function of the
alpha-amylase activity.
Washing Performance
[0257] Washing performance is evaluated by washing soiled test
swatches for 15 and 30 minutes at 25.degree. C. and 40.degree. C.,
respectively; at a pH in the range from 9-10.5; water hardness in
the range from 6 to 15 dH; Ca:Mg ratio of from 2:1 to 4:1, in
different detergent solutions (see above as described above in the
Materials section) dosed from 1 to 5 g/l, such as 3 g/l, dependent
on the detergent with the alpha-amylase variant in question.
[0258] The recombinant alpha-amylase variant is added to the
detergent solutions at concentrations of for instance 0.01-5 mg/l.
The test swatches aree soiled with orange rice starch (CS-28
swatches available from CFT, Center for Test Material,
Holland).
[0259] After washing, the swatches are evaluated by measuring the
remission at 460 nm using an Elrepho Remission Spectrophotometer.
The results are expressed as DeltaR=remission (.degree.
R.quadrature. .quadrature. of the swatch washed with the
alpha-amylase minus the remission of a swatch washed at the same
conditions without the alpha-amylase.
Assays for Alpha-Amylase Activity
1. Phadebas Assay
[0260] Alpha-amylase activity is determined by a method employing
Phadebas.RTM. tablets as substrate. Phadebas tablets (Phadebas.RTM.
Amylase Test, supplied by Pharmacia Diagnostic) contain a
cross-linked insoluble blue-colored starch polymer, which has been
mixed with bovine serum albumin and a buffer substance and
tabletted.
[0261] For every single measurement one tablet is suspended in a
tube containing 5 ml 50 mM Britton-Robinson buffer (50 mM acetic
acid, 50 mM phosphoric acid, 50 mM boric acid, 0.1 mM CaCl.sub.2,
pH adjusted to the value of interest with NaOH). The test is
performed in a water bath at the temperature of interest. The
alpha-amylase to be tested is diluted in x ml of 50 mM
Britton-Robinson buffer. 1 ml of this alpha-amylase solution is
added to the 5 ml 50 mM Britton-Robinson buffer. The starch is
hydrolyzed by the alpha-amylase giving soluble blue fragments. The
absorbance of the resulting blue solution, measured
spectrophotometrically at 620 nm, is a function of the
alpha-amylase activity.
[0262] It is important that the measured 620 nm absorbance after 10
or 15 minutes of incubation (testing time) is in the range of 0.2
to 2.0 absorbance units at 620 nm. In this absorbance range there
is linearity between activity and absorbance (Lambert-Beer law).
The dilution of the enzyme must therefore be adjusted to fit this
criterion. Under a specified set of conditions (temp., pH, reaction
time, buffer conditions) 1 mg of a given alpha-amylase will
hydrolyze a certain amount of substrate and a blue colour will be
produced. The colour intensity is measured at 620 nm. The measured
absorbance is directly proportional to the specific activity
(activity/mg of pure alpha-amylase protein) of the alpha-amylase in
question under the given set of conditions.
2. Alternative Method
[0263] Alpha-amylase activity is determined by a method employing
the PNP-G.sub.7 substrate. PNP-G.sub.7 which is a abbreviation for
p-nitrophenyl-alpha,D-maltoheptaoside is a blocked oligosaccharide
which can be cleaved by an endo-amylase. Following the cleavage,
the alpha-Glucosidase included in the kit digest the substrate to
liberate a free PNP molecule which has a yellow colour and thus can
be measured by visible spectophometry at .lamda.=405 nm (400-420
nm). Kits containing PNP-G.sub.7 substrate and alpha-Glucosidase is
manufactured by Boehringer-Mannheim (cat. No. 1054635).
[0264] To prepare the reagent solution 10 ml of substrate/buffer
solution is added to 50 ml enzyme/buffer solution as recommended by
the manufacturer. The assay is performed by transferring 20 micro l
sample to a 96 well microtitre plate and incubating at 25.degree.
C. 200 micro I reagent solution pre-equilibrated to 25.degree. C.
is added. The solution is mixed and pre-incubated 1 minute and
absorption is measured every 30 sec. over 4 minutes at OD 405 nm in
an ELISA reader.
[0265] The slope of the time dependent absorption-curve is directly
proportional to the activity of the alpha-amylase in question under
the given set of conditions.
Determination of LAS Sensitivity
[0266] The variant is incubated with different concentrations of
LAS (linear alkyl benzene sulphonate; Nansa 1169/P) for 10 minutes
at 40.degree. C.
[0267] The residual activity is determined using the Phadebas.RTM.
assay method or the alternative method employing the PNP-G.sub.7
substrate.
[0268] LAS is diluted in 0.1 M phosphate buffer pH 7.5.
[0269] The following concentrations are used:
500 ppm, 250 ppm, 100 ppm, 50 ppm, 25 ppm, and 10 ppm on no
LAS.
[0270] The variant is diluted in the different LAS buffers to
concentration of 0.01-5 mg/l in a total volume of 10 ml and
incubated for 10 minutes in a temperature controlled water bath.
The incubation is stopped by transferring a small aliquot into cold
assay buffer. It is important that during activity measurement the
LAS concentration is below 1 ppm, in order not to affect the
activity measurement.
[0271] Then the residual activity is determined in duplicate using
the above mentioned Phadebas.RTM. assay or alternative method.
[0272] The activity is measured after subtraction of the blank.
[0273] The activity with no LAS is 100%.
