As used herein, the term "Crr protein" or "Enzyme IIA ^Glc " protein refers to one of the proteins constituting the PTS system.

The Crr protein of the present application may be a protein comprising the amino acid sequence of SEQ ID NO: 18, and a protein consisting essentially of the amino acid sequence of SEQ ID NO: 18, a protein having the amino acid sequence of SEQ ID NO: 18, or the sequence It may be a protein consisting of the amino acid sequence of No. 18, but is not limited thereto.

In addition, the Crr protein of the present application may be a protein consisting of the amino acid sequence of SEQ ID NO: 18, but includes without limitation a sequence having the same activity as the Crr protein, and a person skilled in the art can obtain sequence information from a known database, NCBI's GenBank, etc. have. In addition, the protein comprising the amino acid sequence of SEQ ID NO: 18 of the present application is SEQ ID NO: 18 and at least 60%, 70%, 80%, 83%, 84%, 85%, 86%, 87% of SEQ ID NO: 18 , 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 97%, 98% or 99% homology or identity. In addition, as long as it is an amino acid sequence having such homology or identity and exhibiting biological activity corresponding to the protein, it is apparent that a protein having an amino acid sequence in which some sequences are deleted, modified, substituted or added is also included in the scope of the present application.

In addition, as a polypeptide encoded by a polynucleotide that hybridizes under stringent conditions with a probe that can be prepared from a known gene sequence, for example, a sequence complementary to all or part of a nucleotide sequence encoding the polypeptide, the sequence Polypeptides having the same activity as the protein consisting of the amino acid sequence of No. 18 may also be included without limitation.

That is, in the present application, 'protein or polypeptide comprising the amino acid sequence described in a specific SEQ ID NO:', 'protein or polypeptide comprising the amino acid sequence described in the specific SEQ ID NO:', 'essentially composed of the amino acid sequence described in the specific SEQ ID NO: Even if it is described as 'a protein or polypeptide having an amino acid sequence set forth in a specific SEQ ID NO:' or 'a protein or polypeptide having an amino acid sequence set forth in a specific sequence number,' if it has the same or corresponding activity as a polypeptide consisting of the amino acid sequence of the corresponding SEQ ID NO: It is apparent that proteins having these deletions, modifications, substitutions, conservative substitutions or added amino acid sequences can also be used in the present application. For example, the amino acid sequence N-terminus and/or C-terminal addition of a sequence that does not alter the function of the protein, a naturally occurring mutation, a silent mutation or a conservative substitution thereof. .

The term "conservative substitution" means substituting an amino acid for another amino acid having similar structural and/or chemical properties. Such amino acid substitutions may generally occur based on similarity in polarity, charge, solubility, hydrophobicity, hydrophilicity and/or amphipathic nature of the residues. For example, positively charged (basic) amino acids include arginine, lysine, and histidine; negatively charged (acidic) amino acids include glutamic acid and aspartic acid; Aromatic amino acids include phenylalanine, tryptophan and tyrosine, and hydrophobic amino acids include alanine, valine, isoleucine, leucine, methionine, phenylalanine, tyrosine and tryptophan.

As used herein, the term "homology" or "identity" refers to the degree to which two given amino acid sequences or nucleotide sequences match and can be expressed as a percentage. The terms homology and identity can often be used interchangeably. In the present specification, a homologous sequence having the same or similar activity to a given amino acid sequence or polynucleotide sequence is expressed as "% homology".

Sequence homology or identity of a conserved polynucleotide or polypeptide is determined by standard alignment algorithms, with default gap penalties established by the program used may be used. Substantially, homologous or identical sequences are generally at least about 50%, 60%, 70%, 80% of the entire or full-length sequence under moderate or high stringent conditions. or more than 90% hybrid. Hybridization is also contemplated for polynucleotides containing degenerate codons instead of codons in the polynucleotides.

Whether any two polynucleotide or polypeptide sequences have homology, similarity or identity can be determined, for example, by Pearson et al (1988) [Proc. Natl. Acad. Sci. USA 85]: 2444, using a known computer algorithm such as the “FASTA” program. or, as performed in the Needleman program of the EMBOSS package (EMBOSS: The European Molecular Biology Open Software Suite, Rice et al., 2000, Trends Genet. 16: 276-277) (version 5.0.0 or later), The Needleman-Wunsch algorithm (Needleman and Wunsch, 1970, J. Mol. Biol. 48: 443-453) can be used to determine. (GCG program package (Devereux, J., et al, Nucleic Acids Research 12: 387 (1984)), BLASTP, BLASTN, FASTA (Atschul, [S.] [F.,] [ET AL, J MOLEC BIOL 215] : 403 (1990); Guide to Huge Computers, Martin J. Bishop, [ED.,] Academic Press, San Diego, 1994, and [CARILLO ETA/.] (1988) SIAM J Applied Math 48: 1073) For example, BLAST of the National Center for Biotechnology Information Database, or ClustalW, can be used to determine homology, similarity or identity.

Homology, similarity or identity of polynucleotides or polypeptides is described, for example, in Smith and Waterman, Adv. Appl. Math (1981) 2:482, see, for example, Needleman et al. (1970), J Mol Biol. 48: 443 by comparing the sequence information using a GAP computer program. In summary, the GAP program is defined as the total number of symbols in the shorter of two sequences divided by the number of similarly aligned symbols (ie, nucleotides or amino acids). Default parameters for the GAP program are: (1) a binary comparison matrix (containing values of 1 for identity and 0 for non-identity) and Schwartz and Dayhoff, eds., Atlas Of Protein Sequence And Structure, National Biomedical Research Foundation , pp. 353-358 (1979), Gribskov et al (1986) Nucl. Acids Res. 14: weighted comparison matrix of 6745 (or EDNAFULL (EMBOSS version of NCBI NUC4.4) substitution matrix); (2) a penalty of 3.0 for each gap and an additional 0.10 penalty for each symbol in each gap (or a gap opening penalty of 10, a gap extension penalty of 0.5); and (3) no penalty for end gaps. Thus, as used herein, the term “homology” or “identity” refers to a relevance between sequences.

The polynucleotide encoding the Crr protein of the present application may be referred to as a "crr gene".

In the present application, the term "polynucleotide" has a meaning comprehensively encompassing DNA or RNA molecules, and nucleotides, which are basic structural units in polynucleotides, may include not only natural nucleotides, but also analogs in which sugar or base sites are modified ( Scheit, Nucleotide Analogs, John Wiley, New York (1980); see Uhlman and Peyman, Chemical Reviews, 90:543-584 (1990)).

The polynucleotide sequence of the gene encoding the Crr protein can be obtained from a known database, for example, GenBank of NCBI, etc., but is not limited thereto.

The polynucleotide is 60%, 70%, 80%, 83%, 84%, 85%, 86%, 87%, 88%, 89% of the polynucleotide encoding the Crr protein of the present application or the protein of the present application. , 90%, 91%, 92%, 93%, 94%, 95%, 97%, 98% or 99% homology or identity.

Specifically, the polynucleotide encoding the Crr protein of the present application is at least 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99% or 100% identical to the polynucleotide sequence of SEQ ID NO: 7 It may be a polynucleotide having homology or identity. However, as long as it is a polynucleotide sequence encoding a protein having an activity corresponding to the Crr protein, it is not limited thereto, and it is obvious that it is included in the scope of the present application.

In addition, it is obvious that a polynucleotide that can be translated into a protein having the same amino acid sequence or a protein having homology thereto may also be included due to the genetic code degeneracy of the codon. In addition, a protein having the activity of a protein consisting of the amino acid sequence of SEQ ID NO: 18 by hydridation under stringent conditions with a probe that can be prepared from a known gene sequence, for example, a sequence complementary to all or part of the nucleotide sequence. It may be included without limitation as long as it encodes a sequence. The "stringent conditions" means conditions that allow specific hybridization between polynucleotides. Such conditions are described in, e.g., J. Sambrook et al., Molecular Cloning, A Laboratory Manual, 2nd Edition, Cold Spring Harbor Laboratory press, Cold Spring Harbor, New York, 1989; FM Ausubel et al., Current Protocols in Molecular Biology. , John Wiley & Sons, Inc., New York). For example, genes with high homology are 40% or more, specifically 70% or more, 80% or more, 85% or more, 90% or more, more specifically 95% or more, more specifically 97% or more, In particular, the conditions in which genes having 99% or more homology are hybridized and genes having less homology than that are not hybridized, or 60°C, 1ХSSC, 0.1% SDS, which is a washing condition of normal Southern hybridization, specifically Lists conditions for washing once, specifically 2 to 3 times, at a salt concentration and temperature equivalent to 60°C, 0.1ХSSC, 0.1% SDS, more specifically 68°C, 0.1ХSSC, 0.1% SDS. can do. Hybridization requires that two nucleic acids have complementary sequences, although mismatch between bases is possible depending on the stringency of hybridization. The term "complementary" is used to describe the relationship between nucleotide bases capable of hybridizing to each other. For example, with respect to DNA, adenosine is complementary to thymine and cytosine is complementary to guanine. Accordingly, the present application may also include isolated nucleic acid fragments that are complementary to substantially similar nucleic acid sequences as well as the entire sequence.

Specifically, polynucleotides having homology or identity can be detected using hybridization conditions including a hybridization step at a Tm value of 55° C. and using the above-described conditions. In addition, the Tm value may be 60° C., 63° C. or 65° C., but is not limited thereto and may be appropriately adjusted by those skilled in the art depending on the purpose.

The appropriate stringency for hybridizing polynucleotides depends on the length of the polynucleotides and the degree of complementarity, and the parameters are well known in the art (see Sambrook et al., supra, 9.50-9.51, 11.7-11.8).

In the present application, the microorganism producing the compound may be one in which Crr protein is inactivated.

In the present application, the term "Crr protein is inactivated" means that the expression of the gene encoding the protein is not expressed at all compared to the parent strain or the strain in which the Crr protein is unmodified, or the activity of the protein is absent or reduced even if it is expressed. means that In this case, the decrease is a case in which the activity of the protein is reduced compared to the activity of the protein possessed by the original microorganism due to mutation or deletion of the gene encoding the protein, and inhibition of expression or translation inhibition of the gene encoding it. When the overall protein activity level in the cell is lower than that of the native strain or the strain before modification, it is a concept including a combination thereof.

The inactivation of the Crr protein of the present application is the inactivation of the Crr transcriptional regulator, the inactivation of the protein comprising the amino acid sequence of SEQ ID NO: 18, or the protein encoded by the gene comprising the polynucleotide sequence of SEQ ID NO: 7 including inactivation of

In the present application, the inactivation may be achieved by applying various methods well known in the art. Examples of the method include: 1) a method of deleting all or part of the gene encoding the protein; 2) modification of the expression control sequence to reduce the expression of the gene encoding the protein, 3) modification of the gene sequence encoding the protein so that the activity of the protein is removed or weakened, 4) the gene encoding the protein introduction of an antisense oligonucleotide (eg, antisense RNA) that complementarily binds to the transcript of 5) By adding a sequence complementary to the Shine-Dalgarno sequence to the front end of the Shine-Dalgarno sequence of the gene encoding the protein, a secondary structure is formed to make attachment of the ribosome impossible Way; 6) There is a method of adding a promoter transcribed in the opposite direction to the 3' end of the open reading frame (ORF) of the polynucleotide sequence of the gene encoding the protein (Reverse transcription engineering, RTE), etc., and a combination thereof can also be achieved, but is not particularly limited thereto.

Specifically, in the method of deleting part or all of the gene encoding the protein, a polynucleotide encoding an endogenous target protein in a chromosome is converted into a polynucleotide or a marker gene in which some nucleotide sequences are deleted through a vector for chromosomal insertion in a microorganism. This can be done by replacing As an example of a method for deleting part or all of the polynucleotide, a method for deleting a polynucleotide by homologous recombination may be used, but the present invention is not limited thereto.

In addition, the method of deleting a part or all of the gene may be performed by inducing a mutation using light or a chemical such as ultraviolet light, and selecting a strain in which the target gene is deleted from the obtained mutant. The gene deletion method includes a method by DNA recombination technology. The DNA recombination technique may be accomplished by, for example, injecting a nucleotide sequence or vector containing a nucleotide sequence homologous to a target gene into the microorganism to cause homologous recombination. In addition, the injected nucleotide sequence or vector may include a dominant selection marker, but is not limited thereto.

In addition, the method of modifying the expression control sequence can be achieved by applying various methods well known in the art. As an example of the method, deletion, insertion, non-conservative or conservative substitution of the polynucleotide sequence or a combination thereof to further weaken the activity of the expression control sequence is performed by inducing mutations in the expression control sequence, or having a weaker activity by replacing it with a polynucleotide sequence. The expression control sequence includes, but is not limited to, a promoter, an operator sequence, a sequence encoding a ribosome binding site, and a sequence regulating the termination of transcription and translation.

In addition, the method of modifying the gene sequence is performed by inducing a mutation in the sequence by deleting, inserting, non-conservative or conservative substitution of the gene sequence, or a combination thereof to further weaken the activity of the enzyme, or to have weaker activity. It may be carried out by replacing the improved gene sequence or the modified gene sequence so as to have no activity, but is not limited thereto.

For example, by introducing a mutation in the gene sequence to form a stop codon, the expression of a gene can be inhibited or attenuated.

Hereinafter, the present application will be described in more detail through Examples and Experimental Examples. However, these Examples and Experimental Examples are for illustrative purposes of the present application, and the scope of the present application is not limited to these Examples and Experimental Examples.

Example 1: Chromobacterium violaceum ( Chromobacterium violaceum ) Construction of ATCC 12472-derived violacein biosynthetic gene cluster overexpression vector

To construct a violacein biosynthetic gene cluster overexpression vector, the violacein biosynthetic gene cluster vioABCDE was amplified using the genomic DNA of Chromobacterium violaceum ATCC 12472. Primer 1 (SEQ ID NO: 1) having an EcoRV restriction enzyme site inserted at the 5' end and primer 2 (SEQ ID NO: 2) having a BamHI restriction enzyme site inserted at the 3' end were synthesized. Using this primer pair, a polymerase chain reaction (hereinafter abbreviated as PCR) was performed using the genomic DNA of Chromobacterium violaceum ATCC 12472 as a template to amplify the violacein biosynthesis gene cluster. For PCR conditions, denaturation at 94 °C for 5 minutes, denaturation at 94 °C for 30 seconds, annealing at 60 °C for 30 seconds, and polymerization at 72 °C for 10 minutes were repeated 30 times, followed by polymerization at 72 °C for 7 minutes.

In addition, a trc promoter (SEQ ID NO: 3) in which a KpnI restriction enzyme site was inserted at the 5' end and an EcoRV restriction enzyme site was inserted at the 3' end was synthesized.

The PCR-amplified gene cluster fragment was treated with restriction enzymes EcoRV and BamHI, and the synthesized trc promoter fragment was treated with restriction enzymes KpnI and EcoRV to obtain each DNA fragment. After ligating this to the overexpression vector pECCG117 (Korean Patent Registration No. 1992-007401) having restriction enzymes KpnⅠ and BamHI terminus, it was transformed into E. coli DH5α and LB (Luria Bertani, tryptone per liter) containing kanamycin at 25 mg/ℓ 10 g, yeast extract 5 g, NaCl 10 g, pH 7.0) was spread on a solid medium.

Before selecting the colonies transformed with the vector into which the desired gene was inserted through PCR, it was confirmed that the color of the colonies of the already transformed E. coli DH5α was mostly purple. However, some indigo-colored colonies were found and marked separately (*). Plasmids were obtained from each transformed Escherichia coli DH5α using a commonly known plasmid extraction method, and these plasmids were named pECCG117-Ptrc-vioABCDE and pECCG117-Ptrc-vioABCD*E.

The plasmid pECCG117-Ptrc-vioABCD*E found above was compared with the nucleotide sequence (SEQ ID NO: 4) of the wild-type violacein biosynthesis gene cluster through nucleotide sequence analysis, thereby confirming the amino acid sequence of the mutated VioD protein. Unlike the wild-type VioD amino acid sequence (SEQ ID NO: 5), the mutant VioD amino acid sequence (SEQ ID NO: 6) can be expected to not perform the role of wild-type VioD properly due to the stop codon generated by the mutation, and accordingly, the plasmid pECCG117 The biosynthetic gene cluster of -Ptrc-vioABCD*E can be predicted as a gene cluster capable of biosynthesis only with deoxyviolacein, not violacein. Since it is already known that only deoxybiolacein can be produced using the vioD biosynthetic gene cluster in a mutated or deleted form (August PR et al ., 2000, J Mol Microbiol Biotechnol. 2(4):513-519) , Jiang PX et al ., 2012, Appl Microbiol Biotechnol. 94(6):1521-32, Rodrigues AL et al ., 2013, Metab Eng. 20:29-41), the present inventors separately deoxybiolacein biosynthesis gene The pECCG117-Ptrc-vioABCD*E prepared above was used for the production of deoxyviolacein without constructing an overexpression vector.

Example 2: Violacein biosynthesis gene cluster overexpression vector-introduced strain was prepared and violacein and deoxyviolacein production ability was confirmed

The strains produced by transforming the wild-type and mutant violacein biosynthetic gene cluster overexpression vectors pECCG117-Ptrc-vioABCDE and pECCG117-Ptrc-vioABCD*E prepared in Example 1 into E. coli W3110 strains, respectively, W3110/pECCG117- They were named Ptrc-vioABCDE and W3110/pECCG117-Ptrc-vioABCD*E. When the vector is transformed, it becomes resistant to kanamycin, so transformation was confirmed by growth in LB medium containing 25 mg/L of kanamycin.

Example 3: Introduction of random mutations through UV irradiation of violacein-producing strains

In order to select strains with improved violacein-producing ability, the violacein-producing strain W3110/pECCG117-Ptrc-vioABCDE prepared in the above Example was plated on an LB agar medium containing 25 mg/L of kanamycin and then UV irradiated. Random mutations within the strain were induced. The UV-irradiated plate was incubated at 37°C for 24 hours.

As shown in [Table 2], 13 mutants showed various production capacities and ODs. Among them, the C2 mutant strain showed a 1.6-fold higher violacein production capacity compared to the control group, W3110/pECCG117-Ptrc-vioABCDE, and a pattern in which the ratio of deoxyviolacein was maintained similar to that of the control group was confirmed. is not produced, but it was confirmed that the production capacity of deoxyviolacein was increased by 1.5 times compared to the total production of deoxyviolacein and violacein of the control group.

Example 4: Confirmation of mutations in biosynthetic genes and promoters of violacein mutants C2 and C9

Plasmids were obtained from C2 and C9 mutants with improved violacein or deoxybiolacein-producing ability by the UV irradiation, and it was first confirmed whether there was a mutation in vioABCDE or the promoter region. The plasmid obtained from C2 had no mutations in the biosynthetic operon and promotor regions, but in the plasmid obtained from C9, the 610th nucleotide G of vioD was changed to T, and accordingly, the 204th Glu coding codon had an amber displacement. mutation) was introduced and it was confirmed that it was changed to a stop codon. That is, it is judged that VioD was inactivated by the amber displacement introduced into vioD when the C9 candidate group failed to produce violacein and produced only deoxyviolacein.

Nevertheless, since the C9 mutant has a higher deoxyviolacein-producing ability than the control, sequencing the genes on the genome of the C2 mutant as well as the C9 mutant to identify the mutant gene affecting the production of violacein or deoxyviolacein. .

Example 5: Confirmation of mutations through NGS analysis of violacein mutants C2 and C9

The genomes of the mutant strains C2 and C9 were sequenced and compared with the wild-type strain.

As a result, it was confirmed that the mutants C2 and C9 contained mutations in the gene region encoding Crr, respectively. Specifically, in mutant C2, compared to wild-type crr (SEQ ID NO: 7), amber mutation was introduced as the 43rd nucleotide was replaced with A, so that the 14th codon was changed from Lys to the stop codon, and the 251th nucleotide G was substituted with A As a result, codon 84 was changed from Ser to Asn. (SEQ ID NO: 8), in mutant C9, a frame shift occurred as nucleotide A was inserted at the 12th position of the crr gene, and a stop codon was generated as the 6th codon was introduced with an ochre mutation. was confirmed (SEQ ID NO: 9).

Therefore, in the following Examples, it was attempted to confirm the effect of the mutation on the violacein and deoxybiolacein production ability of microorganisms of the genus Escherichia.

Example 6: W3110 wild-type strain-based crr-deficient strain production

The gene encoding Crr (SEQ ID NO: 7) inherent in microorganisms of the genus Escherichia was deleted by homologous recombination. A one-step inactivation method, a mutagenesis technique using lambda red recombinase developed by Datsenko KA et al., was used (Proc Natl Acad Sci USA., (2000) 97: 6640 -6645) . As a marker for confirming the insertion into the gene, the chloramphenicol gene of pUCprmfmloxC was used (Korean Patent Application Laid-Open No. 2009-007554). Using primer 3 (SEQ ID NO: 10) and primer 4 (SEQ ID NO: 11) having a partial nucleotide sequence of the chloramphenicol resistance gene of a part of the two genes and pUCprmfmloxC gene, pUCprmfmloxC as a template and at 94°C for 30 seconds A gene fragment of about 1300 base pairs was amplified by a polymerase chain reaction method (hereinafter 'PCR' method) in which denaturation, annealing at 55°C for 30 seconds, and polymerization at 72°C for 1 minute were repeated 30 times. The DNA fragment obtained through the above process was eluted after 0.8% agarose gel electrophoresis and used for recombination.

The target E. coli transformed with pKD46 was prepared in a competent state according to the method developed by Datsenko KA et al. (Proc Natl Acad Sci USA., (2000) 97: 6640-6645), and then the 1300 base pair size obtained by the PCR method. was transformed by introducing a gene fragment of The obtained strain was selected from LB having chloramphenicol resistance. It was confirmed that the genes were deleted by confirming that the amplified size was about 1440 base pairs, respectively, through PCR using primers 5 (SEQ ID NO: 12) and primer 6 (SEQ ID NO: 13).

The primary recombinant strain with chloramphenicol resistance removes pKD46 and then introduces pJW168 to remove the chloramphenicol marker gene from the cells (Gene, (2000) 247,255-264). The cells finally obtained were about 340 pairs of amplification products obtained through PCR using primers 5 (SEQ ID NO: 12) and primer 6 (SEQ ID NO: 13), and it was confirmed that each gene deletion was made as intended.

Example 7: Construction of crr mutation vectors of SEQ ID NOs: 8 and 9

In order to construct crr mutation vectors of SEQ ID NOs: 8 and 9, the crr genes of SEQ ID NOs: 8 and 9 containing mutations were amplified using genomic DNAs of mutants C2 and C9, respectively. Primer 7 (SEQ ID NO: 14) and primer 8 (SEQ ID NO: 15) having an EcoRV restriction site inserted at the 5' end and primer 9 (SEQ ID NO: 16) having a BamHI restriction site inserted at the 3' end were synthesized. Violacein biosynthesis gene by performing a polymerase chain reaction (hereinafter abbreviated as PCR) using each genomic DNA of mutant strain C2 as a template using primers 7 and 9 and mutant strain C9 using primers 8 and 9 The cluster was amplified. For PCR conditions, denaturation at 94 °C for 5 minutes, denaturation at 94 °C for 30 seconds, annealing at 60 °C for 30 seconds, and polymerization at 72 °C for 10 minutes were repeated 30 times, followed by polymerization at 72 °C for 7 minutes.

In addition, a trc promoter (SEQ ID NO: 17) in which a KpnI restriction enzyme site was inserted at the 5' end and an EcoRV restriction enzyme site was inserted at the 3' end was synthesized.

The PCR-amplified gene cluster fragment was treated with restriction enzymes EcoRV and BamHI, and the synthesized trc promoter fragment was treated with restriction enzymes KpnI and EcoRV to obtain each DNA fragment. After ligating this to pcc1BAC (Epicentre), a 1-copy vector having restriction enzymes KpnⅠ and BamHI terminus, it was transformed into E. coli DH5α and LB (Luria Bertani, 10 g of tryptone per liter, containing 25 mg/ℓ of chloroamphenicol, Yeast extract 5 g, NaCl 10 g, pH 7.0) was spread on a solid medium.

Plasmids were obtained from each transformed Escherichia coli DH5α using a commonly known plasmid extraction method, and these plasmids were named pcc1BAC-Ptrc-crr (C2) and pcc1BAC-Ptrc-crr (C9).
