INTRODUCTION
[0004] Fungi contain an extensive but unexplored biosynthetic
capacity, and can serve as reservoirs for novel bioactive compounds
(Kobayashi, A., et al., Agric. Biol. Chem., 1988, 52, 3119-3123.;
Kuno, F., et al., J. Antibiot. (Tokyo), 1996, 49, 742-747; Kumar,
C. G., et al, Lett. Appl. Microbiol., 2011, 53, 350-358; Wu, M. C.,
et al., Curr. Opin. Biotechnol., 2012, 23, 931-940; Du, L., et al.,
Angew. Chem. Int. Ed. Engl., 2014, 53, 804-809; Fang, S. M., et
al., Mar. Drugs, 2014, 12, 1788-1814; Leitao, A. L. and Enguita, F.
J., Microbiol. Res., 2014, 169, 652-665).
[0005] Filamentous fungi produce secondary metabolites (SMs) which
have historically been a rich source of lead compounds for the
pharmaceutical industry. Fungi produce 45% of bioactive molecules
from all microbial sources (Berdy, J., J. Antibiot. (Tokyo), 2012,
65, 385-395). These compounds, derived from terpene, polyketide,
and non-ribosomal peptide pathways (Keller, N. P., et al., Nat Rev
Microbiol. 2005, 3: 937-947), display a broad range of useful
antibiotic and pharmaceutical activities. A recent literature
survey of fungal metabolites covering 1500 compounds that were
isolated and characterized between 1993 and 2001, showed that more
than half of the molecules had antibacterial, antifungal or
antitumor activity (Pelaez, F., Handbook of Industrial Mycology
(ed. An, Z.) 49-92 (Marcel Dekker, New York. 2005). Examples of
fungal natural products having therapeutic or economic significance
include the antibiotic penicillin from Penicillium chrysogenum, the
immunosuppressant cyclosporine (a cyclic peptide) from
Tolypocladium inflatum, and the cholesterol-lowering mevinolin
(a.k.a. lovastatin, a polyketide) from Aspergillus terreus.
[0006] Fungal genomes can harbor 50 or more different SM gene
clusters ranging from 20 to greater than 100 kb in size (Nordberg,
H. et al., Nucleic Acids Res., 2014, 42(Database issue), D26-31).
Conservative estimates suggest that there are more than 5 million
fungal species (Blackwell, M., Am. J. Bot., 2011, 98, 426-438), of
which fewer than 5% have been described and less than 1% are
available in the world's culture collections (Colwell, R. R.,
Microbial biodiversity and biotechnology. Washington, D.C.: Joseph
Henry Press; p. 279-88, 1997). In addition, because each of these
fungal genomes may harbor 50 or more different SM gene clusters
ranging from 20 kb to greater than 100 kb in size (Nordberg, H. et
al., Nucleic Acids Res., 2014, 42(Database issue), D26-31), the
number of undiscovered SMs is presumably extremely large.
[0007] Several approaches to induce expression of SM clusters have
been successful. These include overexpressing cluster-specific
transcription factors or enzymatic genes, deleting or
overexpressing chromatin-modifying genes, overexpressing
trans-acting activators and deleting trans-acting inhibitors
(Palmer, J. M. and Keller, N. P., Curr. Opin. Microbiol. 2010, 13:
431-436; Brakhage, A. A. and Schroeckh, V., Fungal Genet. Biol.,
2011, 48, 15-22; Strauss, J. and Reyes-Dominguez, Y., Fungal Genet.
Biol., 2011, 48, 62-69; Hong, S. Y., et al., Toxins (Basel) 2013,
5, 683-702). expression of heterologous SM genes (Itoh, T. et al.,
Methods Mol Biol 2012, 944, 175-182; Chiang, Y. M., et al., J. Am.
Chem. Soc., 2013, 135, 7720-7731; Nielsen, M. T., et al., PLoS ONE
2013, 8: e72871; Tsunematsu, Y., et al., Nat Prod Rep 2013, 30:
1139-1149; Yin, W. B., et al. ACS Synth Biol 2013, 2: 629-634).
[0008] Expression of heterologous clusters in fungi is one approach
to identify SM compounds, biosynthetic SM proteins and genes.
Recently, this approach has been reported for synthesis of the A.
terreus-encoded compounds geodin and asperfuranone in A. nidulans
(Chiang, Y. M., et al., J. Am. Chem. Soc., 2013, 135, 7720-7731;
Nielsen, M. T., et al., PLoS ONE, 2013, 8, e72871). A. nidulans was
also used to heterologously express a dermatophyte-derived gene
cluster responsible for the synthesis of neosartoricin B (Yin, W.
B., et al., ACS Synth. Biol., 2013, 2, 629-634). These studies
utilized a shuttle vector that included a ColE1 origin of
replication, a yeast centromere sequence and an autonomously
replicating sequence. This vector was used to create a single full
length cluster in A. nidulans. These technologies require
considerable time and effort to express just one heterologous
cluster. These technologies are also only compatible with inserts
smaller than about 20 kilobases (kb).
[0009] Large insert DNA cloning vectors are well established in a
variety of systems, including: yeast artificial chromosome (YAC,
Burke, D., et al., Science, 1987, 236, 806-812), bacterial
artificial chromosome (BAC, Shizuya, H., et al., Proc. Natl. Acad.
Sci. USA., 1992, 89, 8794-8797), P1-derived artificial chromosome
(PAC, Ioannou, P. A., et al., Nat. Genet., 1994, 6, 84-89), E.
coli-plant shuttle BAC, also called binary BAC (BIBAC, Hamilton, C.
M., Gene, 1997, 200, 107-116), E. coli-Streptomyces artificial
chromosome (ESAC, Sosio, M., et al., Nat. Biotechnol., 2000, 18,
343-345). However these plasmid systems are not compatible with
fungi. A previously reported E. coli-fungus shuttle plasmid vector
can neither accommodate nor maintain 100 kb or larger DNA fragments
(Yin, W. B., et al., ACS Synth. Biol., 2013, 2, 629-634).
[0010] A. nidulans AMA1 is a fungal replication element that has
been used in an E. coli-fungus shuttle vector for small plasmids
(Gems, D., et al., Gene, 1991, 98, 61-67; Aleksenko, A. and
Clutterbuck, A., J. Fungal Genet. Biol., 1997, 21, 373-387;
Kubodera, T. et al., Biosci. Biotechnol. Biochem., 2000, 64,
1416-1426). There were also fungal shuttle plasmids or vectors
reported for integration (Tiburn, J., et al., Gene. 1983,
26:205-221; Golduran, G. H. and Morris, N. R., Methods in Molecular
Genetics 1995, 6, 48-65 Microbial Gene Techniques Edited by Kenneth
W. Adolph; Kubodera, T., et al., Biosci. Biotechnol. Biochem.,
2000, 64, 1416-1426; Arentshorst, M., et al., Fungal Biology and
Biotechnology, 2015, 2, 2), autonomous replication or
extra-chromosomal maintenance (Gems, D., et al., Gene, 1991, 98, 61
-67; Golduran, G. H. and Morris, N. R., Methods in Molecular
Genetics 1995, 6, 48-65 Microbial Gene Techniques Edited by Kenneth
W. Adolph; Kubodera, T. et al., Biosci. Biotechnol. Biochem., 2000,
64, 1416-1426). However, these shuttle plasmids or vectors cannot
be used to clone and transform very large DNA (such as 20 kb or
larger). A previous attempt to introduce up to 75 Kb of fungal DNA
into Fusarium oxysporum and A. awamori using an Agrobacterium
tumefaciens transformation system yielded few transformants with
large DNA inserts. Furthermore, no attempts to examine stability of
heterologous DNA, let alone expression, were made (Takken, F. L.,
et al., Curr. Genet., 2004, 45, 242-248).
[0011] Bacterial artificial chromosomes (BACs) have been widely
used for genomic DNA sequencing, positional cloning, and mapping in
prokaryotes and eukaryotes including filamentous fungi (Zhu, H., et
al., Fungal Genet. Biol., 1997, 21, 337-347; Nishimura, M., et al.,
Biosci. Biotechnol. Biochem., 1998, 62, 1515-1521; Adler, H. et
al., Rev. Med. Virol., 2003, 13, 111-121; Diener, S. E., et al.,
Fungal Genet. Biol., 2004, 41, 1077-1087; Srivastava, S. K., et
al., PLoS One 2014, 9: e81832). Although large-insert DNA systems
have also been applied for heterologous expression of microbial
natural product biosynthetic pathways and metagenomic studies,
there has been limited success reported (Beja, O., Curr. Opin.
Biotechnol., 2004, 15, 187-190; Lorenz, P. and Eck, J., Nat. Rev.
Microbiol., 2005, 3, 510-516; Ongley, S. E., et al., Nat. Prod.
Rep., 2013, 30, 1121-1138). Challenges with these systems include:
1) DNA cloning bias; 2) small DNA insert size; 3) lack of advanced
heterologous expression hosts and 4) insufficient high-resolution
chemical and data analysis pipelines. One reason for these
challenges is that to date almost all BAC libraries are produced
using partial restriction digestion (Wu, C. C., et al.,
Encyclopedia of Molecular Cell Biology and Molecular Medicine
Volume 3 (2nd Edition), Edited by Meyers R. A., Wiley-VCH Verlag
GmbH: Weinheim, Germany 2004, pp 385-425 2004; Zhang, M., et al.,
Nat. Protoc., 2012, 7, 467-478). Partial restriction digestion can
be biased because the occurrence of restriction sites is highly
variable and non-random in any genome including fungal genomes.
Certain genomic regions can contain an excess of the restriction
sites or lack them altogether, for example in regions of genomic
DNA that contain highly repetitive sequences, such as centromeres
and telomeres (Godiska, R., et al., Bias-Free Cloning of
`Unclonable` DNA for Simplified Genomic Finishing. In DNA
Sequencing III: Dealing with Difficult Templates. Sudbury, M A:
Jones and Bartlett Publishers: 2008). As a result, some sequences
can be difficult or impossible to determine, even with multiple
biased partial digestion libraries and up to 50.times.
coverage.
[0012] Additionally, DNA fragments from rare or frequent cutting
genomic regions can be either too large or too small for DNA
fragment fractionation and can be excluded from cloning.
Fragmentation of high molecular weight (HMW) genomic DNA by
mechanical shearing, such as sonication, nebulization and
hydroshearing, can generate small DNA fragments (10 kb or smaller).
These methods can be unsuitable for preparing fragments ranging
from 100 kb-300 kb. Freeze-thaw cycles have been reported to result
in large DNA fragmentation, but these methods are not efficient
enough for routine use (Osoegawa, K., et al., Genomics., 2007, 89,
291-299).
[0013] Red/ET (Red alpha/beta or RecE/T) tools have been developed
for efficient large DNA or BAC-based recombinant engineering
(Copeland, N. G., et al., Nat. Rev. Genet. 2001, 2: 769-779;
Muyrers, J. P. P. et al., Trends in Bioch. Sci., 2001, 26,
325-331). Engineered large DNA or BACs have been routinely used for
generating transgenic animals, such as mice, and for the functional
study of large genes or pathways in mammals, such as humans
(Johnson, S. J. and Wade-Martins, R. A., Biochem. Soc. Trans. 2011,
39, 862-867).
[0014] BAC-based large gene expression in animal models (Johnson,
S. J. and Wade-Martins, R. A., Biochem. Soc. Trans. 2011, 39,
862-867) cannot be directly applied to study fungal SM pathways or
discovery of natural products (NPs).
[0015] There is thus an unmet need for new methods and compositions
for cloning large stretches of fungal DNA, such as entire clusters
of genes involved in biosynthesis of secondary metabolites.
SUMMARY
[0016] Because of an unmet need for new tools to study fungal
genes, the present inventor has developed vectors and methods for
generating libraries of SM gene clusters that can be propagated and
expressed in a fungal host.
[0017] In some embodiments, the present teachings include a fungal
artificial chromosome (FAC). In various aspects, a fungal
artificial chromosome can comprise at least one bacterial origin of
replication, a bacterial selectable marker gene, a fungal
selectable marker gene and a fungal autonomous replicating element.
In various aspects, a FAC can be a shuttle vector or plasmid that
can replicate in a bacterial host such as, for example, and without
limitation E. coli as well as a fungal host, such as, for example
and without limitation a filamentous fungus such as an Aspergillus.
In some configurations, the Aspergillus can be Aspergillus
nidulans.
[0018] In some configurations, a fungal artificial chromosome of
the present teachings can be a dual-function fungal artificial
chromosome (FACdual). In various configurations, a FACdual can
comprise at least one bacterial origin of replication, a bacterial
selectable marker gene, a fungal autonomous replicating element, an
integration site for recombination with a host, an integrase gene,
and a fungal selectable marker gene. In some configurations, the
integration site can be, without limitation, an attP site. In some
configurations, the integrase gene can be, without limitation, a
fungal codon-optimized phi31 integrase gene. In some
configurations, a FACdual can further comprise a fungal-operative
promoter such as a fungal inducible promoter. In various
configurations, the fungal-operative promoter can be operably
linked to the integrase gene. In various aspects, a fungal
inducible promoter can be an alcA(p) (Romero, B., et al., Fungal
Genet. Biol. 2003 40, 103-114). In various aspects, a fungal
inducible promoter can be a glaA(p) (Smith, T. L., et al., Gene,
1990, 88, 259-262). In various aspects, a fungal inducible promoter
can be a sucA promoter (Roth, A. H., et al., Appl Microbiol
Biotechnol., 2010, 86, 659-670).
[0019] In various configurations, a fungal autonomous replicating
element can be any fungal autonomous replicating element, such as,
without limitation, an AMA1 autonomous replicating element.
[0020] In some embodiments, the present teachings include a fungal
artificial chromosome integration vector (FACint). In various
configurations, a fungal artificial chromosome integration vector
can comprise at least one bacterial origin of replication, a
bacterial selectable marker gene, two fungal DNA sequences in the
same orientation, and a fungal selectable marker gene. In various
configurations, the two fungal sequences can be sequences
homologous to a host fungal DNA. In various configurations, two
fungal homologous DNA sequences can be, for example and without
limitation, Aspergillus 1,007-bp 5'trpC and 1,000-bp 3'trpC
homologous sequences. In various aspects, a FACint can replicate in
a prokaryotic host such as, without limitation, an E. coli. In
various aspects, a FACint can integrate into the genome of a fungal
host such as, without limitation, an Aspergillus fungus such as an
Aspergillus nidulans. In various aspects, a FACint can serve as a
shuttle vector or plasmid. In various aspects, the bacterial
selectable marker gene can be any bacterial selectable marker gene
known to skilled artisans, such as, but not limited to a
kanamycin-resistance gene (kanR).
[0021] In various configurations, a vector of the present
teachings, i.e., a FAC, a FACdual or a FACint of the present
teachings, can further comprise a cloning site comprising a
plurality of recognition sites for endonucleases that bind and cut
DNA at specific sequences. Endonuclease recognition sequences
include recognition sequences of restriction endonucleases from
prokaryotes and homing endonucleases from eukaryotes (as used
herein, "restriction enzymes"). In some configurations, a cloning
site can comprise a plurality of recognition sites for restriction
enzymes that generate incompatible (i.e., non-complementary or
non-palindromic) single-stranded overhangs upon digestion of the
FAC. In some aspects, a cloning site can include recognition
sequences for one or more restriction enzymes such as, without
limitation, Bsr I, I-CeuI, BstXI, I-SceI or a combination thereof.
In some aspects, a recognition sequence can be a recognition
sequence of a restriction enzyme such as, without limitation,
BstXI, I-SceI or a combination thereof. In some aspects, a cloning
site can include a pair of restriction enzyme recognition sites in
a tandem orientation. In some aspects, a cloning site can include a
pair of restriction enzyme recognition sites in an opposing,
"head-to-head" orientation. In some aspects a cloning site can
include, in order, recognition sites for I-SceI, BstXI, BstXI, and
I-SceI. In some aspects, the I-SceI sites can be in a head-to-head
orientation with each other. In some aspects, the BstXI sites can
be in a head-to-head orientation with each other. In some
configurations, a cloning site can further comprise one or more
recognition sites for other restriction enzymes such as, for
example, Bam HI, Hind III, Eco RI, or NotI.
[0022] In various configurations, a vector of the present teachings
can be maintained and can replicate in a prokaryotic host such as,
without limitation, an E. coli, or in a eukaryotic fungal host such
as, without limitation, an Aspergillus such as A. nidulans.
[0023] In some configurations, a vector of the present teachings
can include a low-copy number bacterial origin of replication, an
inducible high-copy number bacterial origin of replication, or a
combination thereof, i.e., both a low-copy number and an inducible
high-copy number bacterial origins of replication. In various
aspects, a low-copy number bacterial origin of replication can be,
for example and without limitation, an oriS. In various aspects, an
inducible high-copy number bacterial origin of replication can be,
for example and without limitation, an oriV. In various
configurations, the high copy number origin of replication can be
controlled by a replication initiation protein gene encoded in the
E. coli host genome or a plasmid. In various configurations, the
replication initiation protein gene can be TrfA. In various
configurations, an inducible promoter can be operably linked to the
replication initiation protein gene. In various configurations, the
inducible promoter can be any bacterial inducible promoter, such
as, without limitation, an arabinose-inducible promoter, a lac
promoter, an IPTG-inducible T3 promoter, an IPTG-inducible T5
promoter or a rhamnose-inducible (rhaBAD) promoter.
[0024] In some configurations, a vector of the present teachings
can include one or more genes for selectable markers for bacteria
such as E. coli, such as, without limitation, a chloramphenicol
resistance gene (camR or CAT), kanR, ampR, genR, tetA, strepR, galK
or a combination thereof. In various aspects, a selectable marker
can be used for positive selection (e.g., selecting for the
presence of ampicillin resistance or galK (galactokinase) activity)
or negative selection (e.g., selecting for the absence of galK
activity (Warming, S., et al., Nucleic Acids Res. 2005, Vol. 33,
No. 4 e36)).
[0025] In some configurations, a vector of the present teachings
can include a fungal selectable marker gene, such as, without
limitation, pyrG, ptrA, trpC or a combination thereof. In some
aspects, a fungal selection marker gene can be a pyrG gene.
[0026] In some configurations, a vector of the present teachings
can include an insertion of DNA from an exogenous source. In

up to 500 kb in length, up to 400 kb in length, up to 300 kb in
length, up to 200 kb in length, or up to 150 kb in length. Thus, in
various configurations, a vector of the present teachings can
include an insert ranging, for example and without limitation, from
30 kb up to 500 kb, from 40 kb up to 400 kb, from 50 kb up to 300
kb, or from 100 kb to 500 kb.
[0028] In various configurations, a vector of the present teachings
can include an insert which can comprise, consist essentially of,
or consist of at least one secondary metabolite (SM) gene cluster.
In various configurations, a vector of the present teachings can
include an insert which can comprise, consist essentially of, or
consist of at least one secondary metabolite (SM) gene cluster and
all genes of this gene cluster encoding a final metabolite product
from a fungus. In various aspect, the SM gene cluster can be from a
fungal species heterologous to a host fungal species of a vector of
the present teachings. In various aspects, the SM gene cluster can
be from a fungal species other than A. nidulans, and the host
fungal species can be A. nidulans. In various configurations, an
insert comprising an SM gene cluster can be up to 500 kb in length,
up to 400 kb in length, up to 300 kb in length, up to 200 kb in
length, or up to 150 kb in length. Thus, in various configurations,

kb, from 40 kb up to 400 kb, from 50 kb up to 300 kb, from 100 kb

various configurations, an SM gene cluster comprised by a vector of
the present teachings can be a complete gene cluster. In some
aspects, expression of an SM gene cluster in a heterologous fungal
host can be used to recreate a biosynthetic pathway of a secondary
metabolite.
[0029] In various configurations, the present teachings include a
host fungus comprising a vector of the present teachings (i.e., a
FAC, a FACdual, or a FACint). In various aspects, the host fungus
can be a filamentous fungus, such as, without limitation, an
Aspergillus fungus. In various aspects, the fungus can be an
Aspergillus nidulans fungus. In various configurations, a host
fungus comprising a vector of the present teachings comprising an
SM gene cluster can express genes of the cluster. Because the genes
of an SM gene cluster comprised by a vector of the present
teachings are in a fungal environment, naturally occurring gene
expression, post-transcriptional and post-translational regulation
and modifications, as well as synthesis of secondary metabolites,
can be duplicated or closely approximated. In some aspects, one or
more genes of an SM gene cluster can be modified to effect an
increase or a decrease in expression levels, or to alter protein
structure.
[0030] In various configurations, a secondary metabolite (SM) gene
cluster comprised by vector of the present teachings can be
modified with one or more targeted insertions, one or more targeted
deletions, or a combination thereof. In various aspects, a
modification can lead to enhanced expression of one or more genes
comprised by an SM gene cluster. In various aspects, a modification
can lead to reduced expression of one or more genes comprised by an
SM gene cluster. In various aspects, a modification can lead to
activation of a cryptic gene. In various aspects, a modification
can be a targeted insertion into a specific site in an SM gene
cluster. In various aspects, a modification can be a targeted
deletion of a portion of an SM gene cluster. In some aspects, the
vector can be a FAC, a FACdual a FACint of the present
teachings.
[0031] In some embodiments, the present teachings include methods
of inserting a DNA sequence into a targeted location in a secondary
metabolite (SM) gene cluster. In various configurations, these
methods can comprise providing a vector of the present teachings
(i.e., a FAC, a FACdual or a FACint of the present teachings)
comprising a secondary metabolite (SM) gene cluster; providing an
insertion DNA comprising, consisting essentially of, or consisting
of a) a first sequence homologous to a sequence flanking a first
side of the targeted location, b) a sequence to be inserted, c) a

the targeted location and d) a bacterial selectable marker;
transforming the vector and the insertion DNA into an E. coli
strain that expresses Red/ET recombinase enzymes; and selecting a
transformed E. coli cell that comprises the bacterial selectable
marker. Without being limited by theory, it is believed that
insertion of a sequence at a targeted location can be achieved
through homologous recombination between the insertion DNA and the
SM gene cluster comprised by the vector. In some configurations,
the bacterial selectable marker of the insertion DNA can be a
marker other than a bacterial selectable marker comprised by the
vector prior to the transformation. In various configurations, the
bacterial selectable marker can be a positive selection marker or a
negative selection marker. In some aspects, the vector can be a
FAC.
[0032] In some embodiments, the present teachings include methods

positive selection marker or a negative selection marker. In some
aspects, the vector can be a FAC of the present teachings.
[0033] In some embodiments, the present teachings include methods
of constructing unbiased libraries in a vector of the present
teachings. In various configurations, these methods can comprise
providing high molecular weight (HMW) genomic DNA from a source of
DNA such as a fungus; mechanically shearing the HMW genomic DNA
into fragments of 100 kb-300 kb in length; generating blunt ends on

BstXI linkers to the blunt ends, thereby generating linker-ligated
DNA fragments; purifying the linker-ligated DNA fragments by pulse
field gel electrophoresis; and ligating the purified and

DETAILED DESCRIPTION
[0040] The present teachings provide vectors and methods for the
production of unbiased large-insert genomic libraries, for
capturing complete sets of large intact SM gene pathways from a
fungus. The vectors can be used to shuttle large intact SM gene
clusters between a fungal host and a bacterial host. A. nidulans
can be used as a host for heterologous expression of SM gene
clusters. In addition, vectors of the present teaching allow
targeted modification of SM gene clusters with insertions and
deletions using homologous recombination.
[0041] The present inventor has constructed unbiased fungal shuttle
BAC (FAC) libraries with average insert sizes of 100 kb or larger
from six sequenced fungi: Aspergillus aculeatus, A. wentii, A.
terreus, Fusarium solani, Penicillium expansum, and P. marneffei.
The average insert size in each library is such that an individual
vector can contain a complete SM pathway, or a fungal secondary
metabolite gene cluster which can range from 20 kb to over 80 kb.
In some configurations, one vector can comprise all the genes of a
SM biosynthetic pathway.
[0042] The new FAC libraries were created using randomly sheared
DNA and without restriction partial digestion, another milestone in
the field, removing bias and thus improving the quality of the
library. With the FAC libraries, the present inventor has
successfully captured 263 of 271 intact SM gene clusters or
pathways predicted from the 6 sequenced fungi as individual FAC
clones (Table 1).
[0043] The present inventor has demonstrated that large vectors
such as vectors comprising intact SM gene clusters can be shuttled
into a fungal host for stable plasmid maintenance. In addition,
heterologous expression in an A. nidulans host of large SM gene
clusters that are at least 150 kb has been achieved. In some
configurations, A vector of the present teachings can contain a
full-length SM gene cluster that can be regulated by the regulatory
elements of a fungal host.
[0044] In some aspects, a vector comprising an intact SM gene
cluster (such as a vector comprising an insert of about 100 kb) can
be modified by a Red/ET technique, for fungal functional SM study.
The present teachings include methods for the precise modification
of fungal intact SM gene clusters at any selected DNA sequence
position. The methods can be used, for example and without
limitation, for activating cryptic, silent and or low-expression SM
gene clusters, characterizing a gene or genetic element within a
fungal SM gene cluster, and natural product (NP) discovery.
Examples of modifications of 55 SM gene clusters or pathways are
listed in Table 2.
[0045] In some configurations, an antibiotic resistance gene (for
example, but without limitation a resistance gene for kanamycin,
ampicillin or carbenicillin, erythromycin, tetracycline, gentamicin
sulfate, penicillin, streptomycin, spectromycin, or
chloramphenicol), can be used to select bacterial colonies
harboring a vector comprising a modified SM gene cluster. Such
vectors can be grown in E. coli on LB media with antibiotics
appropriate for the both the vector and RED/ET selection markers.
In some aspects, a selected colony can be grown within one day.
[0046] In some configurations, the present teachings include a
fusion PCR approach which combines a selectable marker (e.g. KanR
or galK gene) and a promoter (such as, but without limitation,
gpdA(p), alcA(p), glaA(p), or pkiA(A)) as one PCR product for
modifying a SM gene cluster (e.g. FIGS. 4A-B and 5).
[0047] In some configurations, the present teachings include
methods for expressing a toxic SM compound, without the need to
coexpress a resistance gene that can transport a toxic SM compound
out of the cell. These methods use a vector comprising an inducible
strong promoter such as alcA(p). In these methods, cells are
initially grown without an inducing agent. When the cells reach a
sufficient density, an inducing agent is added, and the cells
express the genes of a secondary metabolite pathway. This approach
can be used for the production of a toxic SM compound.
[0048] In some configurations, vectors of the present teaching
provide tools for assembling synthetic SM gene clusters in A.
nidulan by fungal homologous recombination (FIG. 6). Individual
genes (for example Gene1, Gene2, and Gene3, or more, total
.about.100 kb in size) can be either completely synthesized
according to bioinformatics designs or cloned and fused with an
inducible strong promoter (such as, but without limitation alcA(p))
and flanking homologous sequences (about 1 kb, H1, H2, H3, H4 and
more). These genes and the cloning ready vectors (pFAC or pFACdual)
containing the flanking homologous sequences of the synthetic SM
gene cluster (e.g. H1, and H4) can be simultaneously transformed
into A. nidulans to assemble the synthetic SM gene cluster by
homologous recombination. Fungal selection markers such as AfpyroA
and AfriboB (Szewczyk, E, et al., Nat. Protoc., 2006, 1, 3111-3120)
can be used for the selection of a vector with a synthetic SM gene
cluster. Unlike the previous genomic integration reported in the
art (Szewczyk, E., et al., Nat. Protoc., 2006, 1, 3111-3120;
Chiang, Y. M., et al., J. Am. Chem. Soc., 2013, 135, 7720-7731), a
synthetic SM gene cluster-FAC of the present teachings can be
isolated from A. nidulans and then shuttled back into E. coli. In
some configurations, a FAC can be further modified, for example by
adding regulatory elements or genes in E. coli or in vitro.
[0049] In some configurations, the present teachings include
methods for assembly of novel synthetic SM gene clusters in A.
nidulan by fungal homologous recombination (FIG. 6)
[0050] The present teachings disclose three types of vectors for
the cloning of large inserts. These vectors can be used for
replication and maintenance of large inserts as artificial
chromosomes or for integration of large inserts into the host
fungal genome. In various configurations, a plasmid that can be
used as a fungal artificial chromosome can be a P1-based vector, a
BAC-based vector, or a shuttle BAC vector that can be used to
replicate large inserts in E. coli and fungal hosts.
[0051] In various configurations a vector of the present teachings
can contain features for replication and maintenance of the plasmid
in E. coli. A vector can comprise an origin of replication for E.
coli, such as low-copy number origin, for example but without
limitation an origin derived from an F plasmid. A low-copy number
origin of replication can include, without limitation, an oriS. A
vector can also comprise an origin of replication for E. coli that
can be an inducible high-copy replication origin, such as, but
without limitation, an oriV. A vector can also include an E. coli
selection marker gene, such as a gene that confers resistance to an
antibiotic such as, but without limitation: chloramphenicol,
kanamycin, ampicillin or carbenicillin, erythromycin, tetracycline,
gentamicin sulfate, penicillin, streptomycin, or spectromycin. In
some configurations, a vector can also comprise at least one
cloning site, which can be a multiple cloning site. In some
aspects, a cloning site can comprise a pair of restriction sites
wherein digestion with a restriction enzyme generates
non-complementary single-stranded overhangs that can be ligated to
specific linkers. Suitable enzymes include enzymes that can produce
non-complementary single-stranded overhangs, such as
non-palindromic overhangs such as overhangs resulting from
digestion with an enzyme such as, without limitation, BstXI, BseYI,
I-CeuI, I-SceI, PI-PspI, PI-SceI, AIwNI, BgII, BsII, BstAPI, DrdI,
MwoI, PfIMI, or SfiI. In some configuraitons, a second cloning site
can comprise a pair restriction sites which flank the first cloning
site enzyme cut sites wherein digestion with a second enzyme
targeting these sites generates non-complementary single-stranded
overhangs. Suitable enzymes include rare cutters that can create
non-complementary single-stranded overhangs such as, but without
limitation I-SceI, PI-PspI, and I-CeuI. Without being limited by
theory, the combination of these two restriction enzyme site pairs
can facilitate clean excision of the cloned large DNA fragment and
exchange with other FAC plasmids, such as FAC integration plasmids.
In various configurations, the high-copy number origin of
replication can be regulated by a replication initiation protein
that can be integrated into a host E. coli cell's genome on an
inducible promoter, such as but without limitation an arabinose
inducible promoter, a T5 promoter, a T7 promoter, a rhaBAD promoter
or a .beta.-galactosidase promoter. The replication initiation
protein can be, for example and without limitation, TrfA.
[0052] In some configurations, a FAC vector can contain features
for their replication in fungal cells. These include a fungal
origin of replication, such as, but without limitation autonomous
maintenance in Aspergillus (AMA1, SEQ ID NO: 8). A FAC vector can
also contain a fungal selection marker gene, such as but without
limitation, orotidine-5'-phosphate decarboxylase gene (pyrG,
originated from A. parasiticus, SEQ ID NO: 9 and SEQ ID NO: 10),
ptrA, or trpC.
[0053] In some configurations, the present teachings include a FAC
dual-function vector that can be maintained in E. coli as a fungal
artificial chromosome, can be induced to integrate into the fungal
genome, and can be used as a E. coli-fungus shuttle BAC vector. A
dual function vector has the same features as a regular FAC vector
as described supra, and an additional gene cassette: an attP site
and an integrase gene, such as but without limitation a phi31
integrase gene, under the control of fungal inducible promoter,
such as but without limitation, alcA promoter or glaA(p). In
various configurations, the integrase gene can be codon optimized
for fungal expression.
[0054] In various configuration, a FAC system of the present
teachings can be used in a wide variety of fungi, such as and
without limitation Aspergillus aculeatus, A. terreus, A. wentii,
Fusarium solani, Penicillium expansum, P. marneffei, Neurospora
crassa, and fungi belonging to the phylum Ascomycetes.
Definitions
[0055] Various terms are used herein to refer to aspects of the
present teachings. To aid in the clarification of description of
the components of these teachings, the following definitions are
included.
[0056] The term "fungus" as used herein refers to is any member of
the group of eukaryotic organisms that includes unicellular
microorganisms such as, without limitation, yeasts and molds, as
well as multicellular fungi that produce familiar fruiting forms
known as mushrooms. More particularly they are filamentous fungi or
molds, such as, and without limitation, Aspergillus aculeatus, A.
terreus, A. wentii, Fusarium solani, Penicillium expansum, and P.
marneffei.
[0057] "Secondary metabolite (SM)" as used herein refers to a
chemical compound that is not involved in primary metabolism, and
therefore differs from the more prevalent macromolecules such as
proteins and nucleic acids. Thousands of SMs have been described
from various eukaryotic organisms including fungi (Donadio, S., et
al., Nat. Prod. Rep., 2007, 24, 1073-1109).
[0058] "SM gene cluster or pathway" as used herein refers to a set
of biosynthetic genes that comprise polynucleotide sequences
encoding the proteins, such as but without limitation an enzyme,
required for synthesis and activity of a secondary metabolite. SM
gene clusters or pathways implement the conversion of a starting
compound, such as but without limitation a substrate, into a final
compound or NP.
[0059] The term "intact or full-length SM gene cluster or pathway"
used herein refers to a SM gene cluster or pathway contains a
complete set of biosynthetic genes and regulatory elements. Each
fungal genome may harbor 50 or more different intact SM gene
clusters ranging from 20 to more than 100 kb in size (Nordberg, H.
et al., Nucleic Acids Res., 2014, 42(Database issue), D26-31).
Fungal SM clusters usually comprise one or more backbone gene(s)
such as polyketide synthases (PKSs), nonribosomal peptide
synthetases (NRPSs), dimethylallyl tryptophan synthases (DMATs),
and terpene cyclases (TCs), surrounded by genes for modifying
enzymes including, but not limited to, oxidoreductases, oxygenases,
dehydrogenases, reductases, and transferases (Keller, N. P. and
Hohn, T. M., Fungal Genet. Biol. 1997, 21, 17-29; Walton, J. D.,
Fungal Genet. Biol., 2000, 30, 167-171).
[0060] "Regulatory element" as used herein refers to a nucleic acid
sequence element that controls or influences the expression of a
gene, such as a gene within a large polynucleotide insert from a
gene cassette, genetic construct or a FAC vector. A regulatory
element can be, for example and without limitation, a promoter, an
enhancer, a transcription factor or control sequence, a translation
control sequence, a temporal or tissue-specific regulatory element,
a polyadenylation signal sequence, a 5' or 3' UTR, a repressor or a
terminator. Regulatory elements can be homologous or heterologous
to the large polynucleotide insert or intact SM gene cluster to be
expressed from a FAC construct or vector as described herein. When
a FAC vector as described herein is present in a cell such as a
heterologous A. nidulans cell, a regulatory element can be
naturally occurring, endogenous, exogenous, and/or engineered with
respect to the cell.
[0061] "Compatible" as used herein refers to two nucleic acid ends
may mean that the ends are either both blunt or contain
complementary single strand overhangs, such as that created by
mechanically shearing DNA followed by DNA end repair, DNA linker
ligation, or after digestion with a restriction endonuclease. At
least one of the ends may contain a 5' phosphate group, which can
allow ligation of the ends by a double-stranded DNA ligase.
[0062] "BstXI Linker" (Klickstein, L. B. and Neve, R. L., Current
Protocols in Molecular Biology, John Wiley & Sons, Inc. 1991,
5.6.1-5.6.10) as used herein refers to two partially complementary
strands of DNA that are annealed to one another to produce a
double-strand DNA molecule with an overhang complementary to one
end of the BstXI cutting sequences as above. An example of a BstXI
linker for ligation of the blunt ends of large DNA fragments is the
following:
TABLE-US-00001 (SEQ ID NO: 5) BstXI Linker Top 5'-CTGGAAAG-3' (SEQ
ID NO: 6) BstXI Linker Bottom 5'-CTTTCCAGCACA-3'
[0063] The blunt ends of the BstXI linker can be designed to be
complementary to large DNA fragments. For example, the target large
DNA fragments may be mechanically sheared DNA which is polished and
made blunt by DNA end repairing enzyme mixture (Intact Genomics,
St. Louis, Mo.). The blunt DNA can also be modified by non-template
mediated addition of a single A nucleotide to each end of the
target large DNA by Taq polymerase. In this case, the above linker
can be modified with an additional single T nucleotide to the 3' of
BstXI Linker Top strand.
[0064] "Shuttle bacterial artificial chromosome (BAC) vector" means
a BAC vector that can be used for the transfer and the maintenance
of genetic information from one (or more) donor bacterial species
or strain(s) to one or more host organism(s) or strain(s) or
species.
[0065] "FAC vector" as used herein refers to a fungal artificial
chromosome vector, or a shuttle BAC vector between E. coli and A.
nidulans.
[0066] "Library" as used herein refers to a plurality of clones
each comprising an insert sequence and a vector.
Methods
[0067] Methods and compositions described herein utilize laboratory
techniques well known to skilled artisans, and can be found in
laboratory manuals such as Sambrook, J., et al., Molecular Cloning:
A Laboratory Manual, 3rd ed. Cold Spring Harbor Laboratory Press,
Cold Spring Harbor, N.Y., 2001; Spector, D. L. et al., Cells: A
Laboratory Manual, Cold Spring Harbor Laboratory Press, Cold Spring
Harbor, N.Y., 1998; Nagy, A., Manipulating the Mouse Embryo: A
Laboratory Manual (Third Edition), Cold Spring Harbor, N.Y., 2003
and Harlow, E., Using Antibodies: A Laboratory Manual, Cold Spring
Harbor Laboratory Press, Cold Spring Harbor, N.Y., 1999. As used in
the present description and any appended claims, the singular forms
"a", "an" and "the" are intended to include the plural forms as
well, unless the context indicates otherwise.
[0068] The following materials and methods are also used in various
aspects of the present teachings.
[0069] The present teachings provide for the preparation of
ultra-high quality of high molecular weight (HMW) genomic DNA from
a fungus and the generation of an unbiased large insert FAC library
by randomly shearing with average insert size 100 kb or larger. The
large DNA population of a library includes not only fragments of
all biosynthetic loci in the fungal genome with minimal bias, but
also each DNA molecule is large enough (100 kb or larger) to cover
at least one of the intact SM gene clusters.
[0070] High molecular weight (HMW) genomic DNA can be derived from
any cultured, isolated, purified or mixed fungi, including fungi
with published genome sequences. The HMW genomic DNA can be
prepared directly from a population of uncultured fungi in their
natural habitat, environment, or biomass without the need of fungal
isolation and cultivation.
[0071] The techniques of HMW genomic DNA preparation for BAC
cloning have been documented (Wu, C. C., et al, Encyclopedia of
Molecular Cell Biology and Molecular Medicine Volume 3 (2nd
Edition), Edited by Meyers R. A., Wiley-VCH Verlag GmbH: Weinheim,
Germany 2004, pp 385-425; Zhang, M., et al., Nat. Protoc., 2012, 7:
467-478). In some configurations, HMW genomic DNA can include
intact chromosomes or can be megabases in size.
[0072] For preparation of HMW genomic DNA, fungal cells, such as,
but without limitation, spores, germinated spores, protoplasts, or
nuclei can be collected and directly embedded in low-melting
agarose plugs. The low-melt agarose plugs can be from about 0.4% to
about 1% in concentration and can have a final concentration of
about 0.5%. HMW genomic DNA can be purified by treatment with
lauryl sarcosine and proteinase K in 0.5 M EDTA, pH 9.0. HMW
genomic DNA can be prepared by preparing fungal protoplasts (Bok,
J. W. and Keller, N. P., Methods Mol. Biol., 2012, 944, 163-174)
and then embedding the fungal protoplasts in low melt agarose
plugs.
[0073] HMW genomic DNA can be used to generate unbiased large
insert recombinant DNA libraries to cover large intact SM gene
clusters wherein one clone contains an intact SM gene cluster or
pathway. The present teachings provide for preparation of liquid
HMW genomic DNA by either electroelution or Gelase digestion of the
agarose DNA plugs. The liquid HMW genomic DNA can then be
mechanically sheared by hydroshearing, repeated pipetting,
low-speed vortexing or a combination thereof. Conditions for a
given fungal genome can be determined by running sheared HMW
genomic DNA on a CHEFF gel with the size range of about 100 kb to
about 300 kb.
[0074] The E. coli-fungal shuttle BAC vectors or FAC (FIG. 1)
vectors disclosed herein (see Example 1) can be used for BAC/FAC
library construction with average inserts 100 kb or larger. The
present inventor has demonstrated that the large-insert FACs (at
least 150 kb) can be shuttled into the heterologous A. nidulans
host for stable maintenance and NP discovery (FIG. 3, Bok, J. W.,
et al., BMC Genomics, 2015, 16, 343).
Random Shear BAC Cloning Method for Construction of Unbiased FAC
Libraries.
[0075] HMW genomic DNA was sheared as described in Methods. To 400
.mu.l of sheared HMW genomic DNA (100.about.300 kb), 5 .mu.l of DNA
end repairing enzyme mixture (Intact Genomics, St. Louis Mo.), 100
.mu.l of 5.times. DNA end repairing buffer to a total of 500 .mu.l.
The sample is mixed well by gently pipetting with a wide-bore tip
and the reaction is incubated at room temperature for 30 min. The
DNA end repairing enzymes are heat killed by incubating the large
DNA end repair reaction at 70.degree. C. for 15 min. 20 .mu.l each
of 100 .mu.M BstXI linker TOP and Bottom (10{circumflex over (
)}6.about.10{circumflex over ( )}7-fold more molar rate excess
linkers than the large DNA molecules), 61 .mu.l of 10.times. T4
ligation buffer with ATP and 10 .mu.l of large DNA T4 ligase
(intactgenomics) are added immediately and then the reaction is
mixed well by gently pipetting with a wide-bored tip. The linker
ligation reaction is set at room temperature for 3-8 hours. The
linker-ligated large DNA fragments are fractionated and excess
BstXI linkers are removed by 1% agarose CHEFF gel electrophoresis
at 0.5.times. TBE, 6V/cm, 90 s/90 s for 16 hours and 4V/cm, 5 s/5 s
for additional 8 hours. Lambda DNA ladder marker (Intact Genomics)
is used as a control to recover 100.about.150, 150.about.210,
210.about.300 kb large DNA fractions as gel slices, and then the
gel slices are placed into dialysis tubes and the DNA is
electreluted, and then the purified linker-ligated large DNA
fragments are dialyzed against 100 ml of ice-cold and autoclaved
ultra-pure water at least 3 times, for one hour each. The
cloning-ready BstXI-FAC vectors (20 ng/.mu.l, Intact Genomics) are
mixed with the gel-purified BstXI-linker ligated DNA (2.about.3
ng/.mu.l) at 1:3 molar rate, and the ligation reaction is set at
16.degree. C. for overnight. For example, 200 ul large DNA (3
ng/.mu.l) is mixed with 10 ul of the FAC vector (20 ng/.mu.l), 60
.mu.l of 5.times. T4 ligation buffer, 30 .mu.l of BAC cloning T4
ligase (intactgenomics), ligation reaction is set at 16.degree. C.
for overnight, preferably 12.about.18 hours.
Large-Insert FAC Library Construction.
[0076] The large DNA fragments of the library are cloned into FAC
vector(s) and serve as a screening library for covering the fungal
SM gene clusters or pathways in E. coli. Preferably, the
large-insert FAC library has average insert size 100 kb or larger,
therefore it is sufficient to contain at least one intact SM gene
cluster in an individual FAC clone. Furthermore, the large-insert
FAC library is unbiased and a FAC library with only 10.times., or
even 5.times. genome coverage can be enough to capture an entire
set of intact SM gene clusters from a sequenced fungal genome or a
fungal sample. Using the methods described herein, the inventor can
capture a complete set of intact SM gene clusters with 4.about.5
384-well plates of FAC clones (average about 100 kb,
4.about.5.times. genome coverage) from all 6 fungi studied (Table
1; Bok, J. W., et al., BMC Genomics, 2015, 16, 343).
[0077] Because the FAC system is a shuttle BAC system, vectors of
the present teachings can be in the BAC/fosmid library screening
techniques known in the art. To identify intact SM gene
cluster-containing FAC clones, sequence-based approaches can be
used for FAC library screening such as PCR or colony hybridization
(Zhang, H. B. and Wu, C. C., Plant Physiol. Biochem., 2001, 39,
1-15; Kang, H. S. and Brady, S. F., Angew. Chem. Int. Ed. Engl.,
2013, 52, 11063-11067). One application of sequence-based
approaches involves the design of DNA probes or primers which are
derived from conserved regions of already known genes or protein
families, for example but without limitation, pooled FAC DNAs from
each arrayed library are screened using degenerate primers designed
to amplify the conserved domains/regions of PKS or NRPS (Kang, H.
S. and Brady, S. F., Angew. Chem. Int. Ed. Engl., 2013, 52,
11063-11067). Positive FAC clones can be recovered from libraries
by PCR screening of the respective pools, followed by screening of
their plates, columns, and rows from which they are identified.
Another sequence based approach is to use high throughput next
generation sequencing of pooled FAC libraries by plate-column-row
with multiplex barcodes. This strategy will reduce sequence
complexity from whole fungal genomes into FAC pool-level
(plate-column-row), therefore enabling the complete assembly of
pooled FAC clones (each 100 kb or larger). The intact SM gene
clusters will be identified by annotation of completely sequenced
and assembled FAC clones. The individual SM gene cluster-containing
FAC clones will then be de-convoluted by barcodes and
plate-column-row coordinates. The advantage of these sequence-based
approaches is to identify SM gene clusters and their FACs from
fungi without the precondition of genome sequence or even
metagenomes of unculturable fungal community. In the present
teachings, another sequence-based approach is used to sequence the
FAC clone ends by the traditional Sanger sequencing method, then
identify the entire set of intact SM gene cluster-containing FACs
by aligning the FAC end sequences onto the fungal reference genome
sequences. Similarly a next-generation sequence method may be used
for this purpose with FAC DNA pooling and barcoding to reduce the
sequencing cost.
Microbial Strains and Culture Conditions.
[0078] The parental strain RJW256 (pyrG89, pyroA4, Anku70::argB,
.DELTA.ST::afpyrG, veA1) was obtained by a sexual cross between
LO4641 (riboB2, pyroA4, .DELTA.ST::AfpyrG, .DELTA.AN7909::afpyrG,
.DELTA.nku70::argB, veA1) and RJW113.5 (.DELTA.veA::argB, pyrG89).
RJW256 was transformed with FAC plasmids to produce FAC recombinant
strains. AST::AfpyrG indicates that the entire endogenous
sterigmatocystin gene cluster was removed from A. nidulans.
[0079] For antimicrobial activity tests, we used A. nidulans
RDIT9.32, A. fumigatus 293, Candida albicans, Pseudomonas
aeroginosa PAO1, Bacillus cereus U85, and Micrococcus luteus
strains. All of the fungal and bacterial strains were maintained as
frozen glycerol stocks at -80.degree. C. Fungal strains were grown
at 37.degree. C. on glucose minimal medium (GMM, Bok, J. W. and
Keller, N. P., Eukaryot. Cell, 2004, 3, 527-535) and bacterial
strains were cultured on tryptic soy broth medium.
A. nidulans Transformation and the Recovery of SM
Cluster-Containing FACs
[0080] A modified PEG-calcium based transformation method was
applied to improve transformation. The described method (Bok, J. W.
and Keller, N. P., Eukaryot. Cell, 2004, 3, 527-535) was modified
as follows: 200 .mu.L containing 107 A. nidulans RJW256 protoplasts
mixed with 2 .mu.g FAC DNA were gently placed over 200 .mu.L of 30%
PEG 4,000 with 50 mM CaCl.sub.2 in a 1.5 mL centrifuge tube. The
centrifuge tube with protoplasts was incubated 30 min on ice. After
centrifuging the incubated mixture for 5 min at 250.times.g, the
solution was gently mixed using an autopipette. This mixture was
then incubated for 10 minutes at room temperature before 1 mL of
sorbitol-Tris-HCl-CaCl.sub.2 (STC: 1.2M sorbitol, 10 mM Tris-HCl,
10 mM CaCl.sub.2 pH 7.5) buffer was added and gently mixed into the
solution. After transferring the mixture into a 13 mL tube, an
additional 5 mL of STC was added into the tube and gently mixed.
One mL of this final solution was distributed onto regeneration
media to obtain transformants.
[0081] A. nidulans FAC transformants were maintained on culture
plates for three generations for phenotype and chemical screening.
For FAC recovery, we prepared .about.0.3 mL of 106/mL protoplasts
from A. nidulans FAC strains and FAC DNA was isolated by the common
alkali lysis method, and resuspended in 10 .mu.L of TE. One
microliter of recovered DNA was re-transformed back into E. coli
cells (BAC cells, Intact Genomics).
Fungal Genomic DNA Extraction
[0082] Fungal DNA was extracted from lyophilized mycelia using
previously described techniques (Bok, J. W. and Keller, N. P.,
Methods Mol. Biol., 2012, 944, 163-174) to perform PCR
reaction.
Antimicrobial Screening
[0083] A disc-diffusion method (Bauer 1966) was used for antibiotic
activity-guided screening. One plate of each A. nidulans FAC strain
was inoculated on solid GMM and incubated for seven days at
37.degree. C. Subsequently, the entire contents of the plates were
collected and lyophilized for 48 hours. Samples were then
pulverized with mortar and pestle prior to the addition of 10 mL of
methanol. Air-dried methanol extracts were dissolved in 150 .mu.L
methanol for activity testing. Media preparation for antibacterial
assays were performed as previously described (Bok, J. W. and
Keller, N. P., Eukaryot. Cell, 2004, 3, 527-535). For antifungal
assays, 106 spores mentioned in the section above were embedded in
5 mL soft GMM agar (0.75% agar) and overlaid on solid GMM. 10 .mu.L
out of the 150 .mu.L methanol extract above was loaded on a 1 cm
diameter paper disc for each assay. Assay plates were incubated for
24 to 48 hour at 37.degree. C. and observed for antimicrobial
activity.
LC-HRMS Analysis
[0084] Five plates of A. nidulans FAC strain, for example and
without limitation, AtFAC6J7 were inoculated on solid GMM and
incubated for seven days at 37.degree. C. Subsequently, the entire
contents of the plates were collected and lyophilized for 48 hours.
Samples were then pulverized with mortar and pestle prior to the
addition of 10 mL of methanol. Air-dried methanol extracts were
then further extracted with organic solvent
(chloroform:methanol:ethylacetate=8:1:1). Organic extracts were
evaporated to dryness and stored at -20.degree. C. until
analysis.
[0085] Organic extracts obtained were resuspended in methanol to a
final concentration of 2 .mu.g/.mu.L. For each analysis, 40 .mu.g
of sample was loaded onto a LUNA.RTM. C18 column (150 mm.times.2
mm; 3 .mu.m particle size) (Phenomenex, Torrance, Calif.).
Chromatography was performed using an AGILENT.RTM. 1150 LC system
(Agilent, Santa Clara, Calif.) at a flow rate of 200 .mu.L/min. The
following gradient was employed (Buffer A: water with 0.1% formic
acid, Buffer B: acetonitrile with 0.1% formic acid): time 0 min, 2%
B; 35 min, 70% B; 54 min, 98% B. A 1:7 split was employed
post-column, resulting in a flow rate of 25 .mu.L/min being
directed to the mass spectrometer. A Q-EXACTIVE.TM. mass
spectrometer (Thermo Fisher Scientific, Waltham, Mass.) was used
for MS analysis with the following settings: capillary temperature
275.degree. C., sheath gas 4 (arbitrary units), spray voltage 4.2
kV. Full MS spectra were acquired at 35,000 resolution for the mass
range m/z 200 to 1500 for all samples. Following each full MS scan,
the top 5 most intense ions were selected for a dependent MS2 scan.
MS2 was conducted using higher-energy collisional dissociation
(HCD) with a normalized collision energy of 30%. Three biological
replicates of AtFAC6J7 extracts were prepared and analyzed in
technical duplicate, followed by the data workup described
below.
Data Analysis, Informatics, and Software
[0086] The SIEVE software suite (Thermo Fisher Scientific, Waltham,
Mass.) was used for component detection and relative quantification
of ions produced by electrospray during small molecule LC-HRMS.
Component detection was performed using a mass tolerance of 10
part-per-million (ppm) and a retention time window of 2.5 min. A
minimum intensity of 5.times.10.sup.6 was selected as the threshold
for defining a peak as a component. For each component, a selected
ion chromatogram was created and the integrated intensity of the
peak was calculated. Peak areas were normalized based on total ion
current. To increase statistical power and confidence of the final
analysis, the procedure adopted here involved a decoy approach to
multiple hypothesis testing. Specifically, the replicate data
AtFAC6J7 was subjected to a uniqueness filter against processed
LC-HRMS data generated from a control group of strains containing
empty vectors, as well as 13 other strains containing a variety of
other FACs with unique genetic content. For dereplication, all
components were initially searched against a targeted accurate mass
database consisting of known fungal metabolites produced by A.
nidulans using a mass tolerance of 3 ppm. A dozen of these known
compounds were present at consistent levels in nearly all samples,
and were monitored to rapidly identify highly perturbed systems.
All components were also searched against a comprehensive accurate
mass database consisting of over 13,000 known fungal secondary
metabolites. This fungal database was prepared using Antibase
(2011), Dictionary of Natural Products (2013), as well as
additional fungal natural products found in the literature (Caboche
et al. 2008; Andersen et al. 2013).
Vector General Descriptions.
[0087] The BstXI Linker overhang is not complementary to itself,
nor is the BstXI-cut vector (above). Upon ligation of the
linker-ligated large DNA fragments and vector, the preferred
ligation reaction product can be a circle containing one vector
joined to one large DNA fragment via a single adapter at each end.
This molecule may be transformed into host cells to produce a
clone.
EXAMPLES
[0088] The present teachings including descriptions provided in the
Examples that are not intended to limit the scope of any claim or
aspect. Unless specifically presented in the past tense, an example
can be a prophetic or an actual example. The following non-limiting
examples are provided to further illustrate the present teachings.
Those of skill in the art, in light of the present disclosure, will
appreciate that many changes can be made in the specific
embodiments that are disclosed and still obtain a like or similar
result without departing from the spirit and scope of the present
teachings.
Example 1
[0089] This example describes pFAC plasmid, a vector of the present
teachings that maintains extra-chromosomes in A. nidulans.
[0090] In the present teachings, a FAC vector (pFAC, FIG. 1A, SEQ
ID NO: 7) is a BAC-based shuttle vector that can shuttle large DNA
between E. coli and A. nidulans hosts. Several features are
required for maintaining the plasmid in E. coli, including two E.
coli origins of replication: oriS and oriV. The first replication
origin, oriS, is derived from a low-copy F plasmid for BAC-based
large DNA cloning and library construction. The second replication
origin, oriV, is an inducible high-copy replication origin oriV,
which can produce higher yield of large inserts when grown in E.
coli containing a TrfA gene under the control of an arabinose
promoter when they are grown on arabinose containing media. pFAC
also contains a chloramphenicol-resistance gene (cat) for plasmid
selection. For cloning purposes, the plasmid contains a large DNA
cloning site comprising pair of BstXI sites designed next to each
other in oppose orientations. When digested with BstXI, this
configuration produces a pair of identical BstXI overhangs, that
are not self-complimentary, but are complimentary to unique BstXI
linkers. Therefore, the digested vector will not religate itself,
nor will the linkers concatermerize easily. Two I-SceI homing
restriction sites were inserted flanking the BstXI cloning site in
reverse orientations. These sites facilitate clean excision of the
cloned large DNA fragment and exchange with pFACint cloning vector
(see example 2).
[0091] pFAC also contains features required for use in A. nidulans.
These include a third replication origin, AMA1, the autonomous
maintenance in Aspergillus (AMA1, SEQ ID NO: 8). This sequence is
required for maintaining large intact SM pathways as
extra-chromosomal elements, or FACs. pFAC also contains a fungal
selection marker gene, the orotidine-5'-phosphate decarboxylase
gene (pyrG from A. parasiticus, SEQ ID NO: 9 & 10).
Example 2
[0092] This example describes pFACint, a FAC integration
vector.
[0093] FAC integration vector (pFACint, FIG. 1B, SEQ ID NO: 11) is
a BAC-based shuttle BAC vector that can shuttle large DNA between
E. coli and A. nidulans hosts. Several features are required for
maintaining the plasmid in E. coli, including two E. coli origins
of replication: oriS and oriV. The first replication origin, oriS,
is derived from a low-copy F plasmid for BAC-based large DNA
cloning and library construction. The second replication origin,
oriV, is an inducible high-copy replication origin oriV, which can
produce higher yield of large inserts when grown in E. coli
containing a TrfA gene under the control of an arabinose promoter
when they are grown on arabinose containing media. pFACint carries
kanamycin-resistance gene (kan) as a selection marker gene or
cloning purposes, the plasmid contains a large DNA cloning site
comprising pair of BstXI sites designed next to each other in
oppose orientations. When digested with BstXI, this configuration
produces a pair of identical BstXI overhangs, that are not
self-complimentary, but are complimentary to unique BstXI linkers.
Therefore, the digested vector will not religate itself, nor will
the linkers concatermerize easily. Two I-SceI homing restriction
sites were inserted flanking the BstXI cloning site in reverse
orientations. These sites facilitate clean excision of the cloned
large DNA fragment and exchange with pFAC cloning vector. The
I-Sce-I homing restriction sites also facilitate clean excision of
the large intact SM gene pathways from the genomic integration site
of the heterologous host A. nidulans.
[0094] pFACint also contains features integrating the plasmid into
the A. nidulans genome: 1,000-bp 3'trpC (SEQ ID NO: 12) and
1,007-bp 5'trpC (SEQ ID NO: 13) homologous sequences, which were
inserted flanking the I-Sce I restriction sites in the same
orientations, thus enabling fungal site-specific integration of
large pFACint clones into the A. nidulans trpC gene, which encodes
a polypeptide homologous to polyketide. The plasmid also contains a
fungal selection marker gene, the orotidine-5'-phosphate
decarboxylase gene (pyrG, from A. parasiticus).
Example 3
[0095] This example describes the vector pFACdual.
[0096] pFACdual plasmid, which also substantially corresponds pFAC
plasmid except that it includes an additional gene cassette: an
attP site and a fungal codon-optimized phi31 integrase gene under
the control of fungal inducible promoter, such as alcA(p).
Therefore, the large DNA pFACdual clones are usually maintaining as
FAC and also be able integrated into the fungal genome with an attB
site whenever it is needed.
[0097] pFACdual vector is a fungal dual-function vector (pFACdual,
FIG. 1C, SEQ ID NO: 14), and can act as both a fungal artificial
chromosome and an inducible fungal genomic integration vector, or
it can be used as an E. coli-A. nidulans shuttle BAC vector.
pFACdual has similar features as pFAC (see Example 1), but pFAC
dual has an additional gene cassette: an attP site and a fungal
codon-optimized phi31 integrase gene (SEQ ID NO: 16 and SEQ ID NO:
17) under the control of the inducible alcA fungal promoter
(alcA(p), SEQ ID NO: 15). Therefore, the large DNA pFACdual clones
are usually maintained as a FAC but can be induced to integratd
into the fungal genome with an attB site.
Example 4
[0098] This example illustrates the preparation of high molecular
weight A. wentii DNA.
[0099] Aspergillus wentii strain DTO 134E9 was used as a proof of
concept. Different fungal species/strain starting materials were
compared to test for quality of high molecular weight (HMW) genomic
DNA: spores, germinated spores, protoplasts, or nuclei obtained
from protoplasts. The protoplast preparation method was performed
as previously described (Bok, J. W. and Keller, N. P., Eukaryot.
Cell, 2004, 3: 527-535). To isolate nuclei, protoplasts were lysed
with 0.5% Triton X-100 in HMW DNA preparation buffer (0.5 M
Sucrose, 80 mM KCl, 10 mM Tris, 10 mM EDTA, 1 mM sperm idine, 1 mM
spermine, pH 9.4). The protoplasts in buffer were gently mixed,
incubated on ice for 30 minutes, and the resulting nuclei pelleted
at 1,800.times.g for 20 minutes. To prepare low melting agarose
plugs of HMW DNA, the pellet (.about.5.times.10.sup.8)--of nuclei,
protoplasts, germinated spores, or spores--was resuspended with the
HMW DNA preparation buffer to a total volume of 0.6 mL, and an
equal volume of 1% low melting agarose was then added to the buffer
to a total volume of 1.2 mL at 45.degree. C. This was sufficient to
make 10 plugs (about 100 .mu.L per plug) which solidified at
4.degree. C. The plugs were then incubated at 50.degree. C. for 48
hours in 1 mL lysis buffer/plug: 0.5 M EDTA, pH 9.0, 1% lauryl
sarcosine, 1 mg/mL proteinase K. Finally, the plugs were
extensively washed in 10-20 volumes of the following buffers for
one hour for each wash: once with buffer 1 (0.5 M EDTA, pH 9.0-9.3
at 50.degree. C.), once with buffer 2 (0.05 M EDTA, pH 8.0 on ice),
three times with buffer 3 (ice cold TE plus 0.1 mM phenylmethyl
sulfonyl fluoride (PMSF) on ice), three times with buffer 4 (ice
cold TE on ice) and finally all plugs were stored in TE at
4.degree. C. In order to estimate the size and yield of the
extracted DNA, plugs were assessed using pulsed field gel
electrophoresis (PFGE) (Bio-Rad CHEF Mapper, Hercules, Calif.). The
final quality check conditions for the HMW genomic DNA were 6 V/cm,
10 sec to 1 min switch time for 12-16 hours at 14.degree. C. by
PFGE, along with appropriate HMW size markers (Zhang, M. et al.,
Nat. Protoc., 2012, 7, 467-478). The highest quality and quantity
of HMW genomic DNA was obtained from the protoplast preparation
(FIG. 2A). FIG. 2A shows a CHEF gel that contains A. wentii HMW
genomic DNA ranging from greater than 50 kb but mainly Mb sizes of
DNA fragments.
Example 5
[0100] This example illustrates the construction of unbiased
shuttle BAC library of A. wentii DNA.
[0101] The HMW genomic DNA obtained from the protoplast preparation
in Example 2 ranged from 50.about.>1,000 kb (mainly megabase
sized fragments). The HMW DNA from three plugs was end-repaired
with the DNA end repair enzyme kit (Intact Genomics) in a total
volume of 500 .mu.L with 10 .mu.L of the end repair enzymes which
were then heat inactivated (70.degree. C., 15 min). The resulting
DNA was ligated with BstXI adaptors (10 .mu.L of 100 .mu.M each)
and 10 .mu.L ligase (2 U/.mu.L, Intact Genomics) in a total volume
of 700 .mu.L. Gel-fractionated DNA fragments ranging from 100 to
200 kb were purified by PFGE. Purified large DNA fragments (about
100 .mu.L 1-3 ng/.mu.L) were ligated into the cloning ready BAC
BstXI shuttle vector (pFAC) at 16.degree. C. for .about.18 hours.
Next, the ligated DNA mixture was electroporated into
electroporation competent E. coli cells (BAC cells, Intact
Genomics). Small-scale ligations and transformations (1 .mu.L DNA
per 20 .mu.L cells) were used to judge the cloning efficiency. The
insert sizes of about 50 BAC clones were determined and confirmed
to include inserts of about 100 kb using CHEF gel electrophoresis
and NotI digestion of random selected BAC clones in pFAC vector.
FIG. 2B illustrates that the average insert size was estimated at
.about.100 kb (M, Lambda ladder Marker). Once the suitability of
the ligated DNA was confirmed, large-scale ligations and
transformations were conducted to achieve at least 7,680 clones for
colony picking (20.times.384-well plates) for the unbiased shuttle
BAC library.
Example 6
[0102] This example illustrates BAC/FAC end sequencing, and select
SM cluster-containing candidate FAC clones.
[0103] BAC-end sequences of 1,536 clones from the unbiased Random
Shear FAC library of A. wentii were completed by the Sanger BigDye
sequencing method. The software Phred was used for base calling and
sequence trimming. Vector masking was achieved using the DNAStar
SeqMan Pro software package. The BAC end sequences were aligned
against the A. wentii reference genome sequence by BLAST Assembled
Genomes (NCBI). All 47 SM clusters-containing candidate FAC clones
were successfully identified based on the FAC end sequence flanking
one end of a SM cluster and the other FAC end sequence flanking the
other end of the same SM cluster.
Example 7
[0104] This example illustrates construction of unbiased shuttle
BAC library of A. wentii DNA and heterologous expression of SM
clusters as FACs in A. nidulans.
[0105] A. wentii was used as an example for shuttle BAC DNA library
construction, and it has a fully sequenced genome containing 47
annotated SM gene clusters (Cerqueira, G. C., et al., Nucleic Acids
Res., 2013, 42(Database issue), D705-D710). High molecular weight
genomic DNA was prepared from A. wentii (see Example 4) and
construction of the unbiased FAC library (see Example 5) resulted
in .about.20.times. genome coverage of the A. wentii genome, or a
total of 7,680 FAC clones with an average insert size of 100 kb
(FIG. 2A-B). The FAC library was arrayed into 384-well plates and
both ends of 1,536 FAC clones were sequenced. Sequence alignment of
these end sequences with the A. wentii reference genome was used to
identify SM-BAC clones or candidate FACs containing all 47 SM gene
clusters (Table 1). In addition, at least 10 of 56 SM clusters of
A. terreus are located near telomeres and some telomeric sequences
are still not complete in the whole genome sequence database. These
data illustrate that these methods successfully overcome the
potential bias against telomeric sequences in conventional BAC
library construction through the introduction of randomly sheared
genomic DNA into the FAC vectors.
Example 8
[0106] This example illustrates the validation of shuttle functions
of FACs.
[0107] To date hundreds of FACs (ranging from 70 to 150 kb in size)
were used for heterologous expression and analysis through
transformation into A. nidulans. To validate the shuttle function
of FACs, we also extracted five of the 15 FAC DNAs from transformed
A. nidulans strains and successfully transformed FAC DNA back into
E. coli (FIG. 3). A. nidulans was transformed with different FAC
clones as determined by return of prototropy on medium without
uracil and uridine. Forty or more colonies of E. coli each were
then assessed from the recovery of the FACs in FIG. 3A-C
respectively. The results show the recovery of FAC examples from
all 3 A. nidulans transformants: AtFAC9O3 (.about.100 kb),
AtFAC9A23 (.about.80 kb), and AtFAC7A10 (.about.90 kb)
respectively. The 2nd and 3rd (D) lane(s) on the left hand side of
the gels is the control FAC used to transform A. nidulans. All
recovered FACs were digested with NotI, there is no obvious large
mutation observed. M, Lambda ladder Marker. This was the first
demonstration of the capability of AMA1 in supporting autonomous
replication (FAC) of large DNA constructs at least 150 kb in A.
nidulans. The present inventor and his collaborators the first to
demonstrate that the FAC system allows for extrachromosomal
replication of at least 150 kb in A. nidulans (Bok, J. W., et al.
BMC Genomics, 2015, 16, 343).
Example 9
[0108] This example illustrates LC-HRMS linked FAC SM
discovery.
[0109] For the initial identification and structure elucidation of
SM compounds through FACs, A. nidulans AtFAC9D19 strain samples
were prepared as described in the Methods section. A. nidulans
AtFAC9D19 was found to produce the insecticide compounds:
alantrypinone, serantrypinone, alantrypinene B, alantryleunone. A.
nidulans AtFAC6J7 strain was also selected for initial
proof-of-concept experiments, as it contained a cluster highly
homologous to the recently characterized hexadehydroastechrome
cluster in A. fumigatus (Yin, W. B., et al., ACS Synth. Biol.,
2013, 2, 629-634,). AtFAC6J7 contains seven out of the eight genes
found in the corresponding A. fumigatus cluster. The gene not
present in this A. terreus cluster, hasG, encodes for an FAD
binding protein responsible for converting a prenyl to a
methylbutadienyl side chain to produce hexadehydroastechrome from
astechrome. AtFAC6J7 metabolites were identified by analyzing
organic extracts of the A. nidulans AtFAC6J7 transformant and
control A. nidulans using LC-HRMS. Following data acquisition,
Sieve software was used for component detection and relative
quantitation (see Methods). When comparing AtFAC6J7 extracts to
control sample extracts (wild type and other FAC strains), a
compound that was present only in the AtFAC6J7 extract was
identified as terezine D by both accurate mass (0.3
part-per-million error) and tandem mass spectrometry (MS/MS or
MS2). Terezine D is a stable intermediate of astechrome
biosynthesis (Watanabe, T., et al., Bioorg. Med. Chem., 2009, 17,
94-111; Bok, J. W., et al. BMC Genomics, 2015, 16, 343).
Example 10
[0110] This example illustrates an antibiotic activity test against
FAC clones.
[0111] An antibiotic activity test was performed 14 FAC clones. Ten
pl out of 150 .mu.l methanol extract from FAC transformants
cultured on GMM plate for 7 days at 37.degree. C. were loaded on
small disc (diameter: 1 cm) for antimicrobial activity test against
Aspergillus spp., Candida albicans, Bacillus cereus, Micrococcus
luteus and Pseudomonas aeruginosa. Antibiotic activity was observed
against Bacillus cereus with two FAC extracts (Bok, J. W., et al.
BMC Genomics, 2015, 16, 343).
Example 11
[0112] This example illustrates FAC recombineering and activating
silent SM gene clusters.
[0113] Red/ET tools were used to elucidate the biosynthesis of
benzomalvins from A. terreus FAC AtFAC9J20. Two smaller-size
constructs (33.372 kb AtFAC9J20.DELTA.#1 and 68.988 kb
AtFAC9J20.DELTA.#2) were created from the FAC clone AtFAC9J20
(102.715 kb) using the NIH BAC recombineering tool with the Red/ET
homologous recombination. We also deleted 5 genes
(AtFAC9J20.DELTA.Mtase, AtFAC9J20.DELTA.NRPS1,
AtFAC9J20.DELTA.NRPS2, AtFAC9J20.DELTA.NRPS3, and
AtFAC9J20.DELTA.PKS) in the benzomalvin cluster to obtain 5
additional FAC mutation constructs that helped to precisely
elucidate biosynthetic pathway benzomalvin efficiently and
effectively.
[0114] To activate a weakly expressed SM gene cluster in FAC
AtFAC7O19, we have successfully inserted the fungal strong promoter
gpdAp in front of the start codon `ATG` of the transcription factor
(TF) gene in this cluster. FAC recombineering was performed as a
two step process. The inventor inserted the galK gene and selected
Gal+ colonies on minimal media plus chloramphenicol and galactose
and then replaced galK with the gpdA promoter by counter-selecting
galK- colonies on minimal media plus chloramphicol,
2-deoxy-galactose, and glycerol. Eight out of eight trials produced
FAC mutation constructs.
[0115] Fusion PCR was performed (FIG. 4A) to combine the selectable
marker (e.g. KanR or galK gene) and a promoter (gpdA(p) or any
genetic element) as one PCR product for FAC recombineering. The
strong fungal promoter gpdAp was inserted in front of the ATG start
codon of SM cluster genes in FAC AtFAC7O19 with a kanamycin
resistance gene. The Fusion PCR reactions are shown schematically
in FIG. 4A (H1 and H2, homology sequences 1 and 2, respectively;
cat, chloramphenicol acetyl transferase gene; FAC, origins of
replication). For construction of the fusion PCR product of Kan
gene and gpdA promoter, the primers used were: 38TF-Kan-leftendF
(5'-TGGGACTTTGTCGCTCACGATTCGCCGAGTTGTATGGGCTGACCAGTGACcgacctgcagcctgttga--
3', SEQ ID NO: 1) and Kan-leftendR
(5'-GGTGCCCCAAGCCTTGGATCCGTCGAGGCTGATCAGCGAgctc-3', SEQ ID NO: 2);
gpdA-rightendF
(5'-TCGCTGATCAGCCTCGACGGATCCAAGGCTTGGGGCACCtgcgtt-3', SEQ ID NO: 3)
and 38TF-gpdA-rightendR
(5'-TCCTCATGAATTAGATGGTTAGATGGACCTACCATCAGGATAGGTTCCATtgtgatgtctgctcaagcg-
gg-3', SEQ ID NO: 4). The result of the one-step targeting event is
the insertion of constitutively active Kan-resistance gene next to
gpdAp into a defined position on the FAC by selection on LB media
with kanamycin and chloramphenicol for the maintenance of the
engineered FAC. The fusion PCR insertions were confirmed with PCR
followed by Notl restriction analysis of FAC DNA from 7 clones
after the insertion of the kan-gpdAp selection cassettes, as shown
in the gels in FIG. 4B. The first lane is unmodified FAC AtFAC7O19
DNA, which was included as a control. All tested clones show the
same pattern, had the intended insertion but no obvious mutation on
the pulse field gel. M, Lambda ladder Marker. The bacteria are now
phenotypically Kan+.
[0116] An example of recombineering using the modified RED/ET tools
includes the deletion of 5 genes of AtFAC9J20 individually with the
galK selection cassette. FIG. 5 shows the NotI restriction analysis
of FAC miniprep DNA from 4 clones each were confirmed by PCR (M,
Lambda ladder Marker). The second to last lane contains unmodified
AtFAC9J20 DNA, which was included as a control. AtFAC9J20 contains
2 SM gene clusters. The five genes, all members of the same
cluster, are 1.239-kb Mtase (dimethylallyltryptophan
N-methyltransferase) gene, 3.334-kb NRPS1, 7.284-kb NRPS2, 7.815-kb
NRPS3, and 7.741-kb PKS genes. Each set of 4 tested clones show the
same pattern, and therefore had the intended deletion. No obvious
mutations were detected by PCR, sequencing, or on the pulse field
gel.
[0117] All engineered FACs were successfully transformed back into
the A. nidulans host strain. Initially, heterologous expression of
the intact FAC AtFAC9J20 identified a group of methylated NRPS
products, which we successfully identified as belonging to
benzomalvins family (benzomalvin A and benzomalvin E). Benzomalvin
A is an indoleamine 2,3-dioxygenase (IDO) inhibitor with the
potential of immune-therapy for cancer. With current FAC
recombineering, we then observed a parallel 10,000-fold drop in
signal of the NRPS products in the gene deletion mutants
AtFAC9J20.DELTA.NRPS1 and AtFAC9J20.DELTA.NRPS2, which supports
that these two NRPS are involved in the biosynthesis directly. We
also observed accumulation of the expected biosynthetic precursors
in our deletion mutants. In addition, accumulation of unmethylated
intermediates in AtFAC9J20.DELTA.Mtase demonstrates identification
of the methyl-transferase responsible for NRPS tailoring. In
conclusion, we have established the biosynthesis of a known NRPS
that has long eluded the field using the FAC technology and FAC
deletants. These deletants not only allow us to see loss of their
corresponding gene products, but also accumulation of biosynthetic
precursors.
