Refers to a gene that expresses a product that is substantially the same as the product. In the present invention, “substantially the same” refers to having the same kind of activity and regulatory mechanisms as the NCBI Grant No. NCg10936 gene product.
- inactivation may mean that the cell or enzyme does not exhibit an activity level measured in cells of the same species or comparable original enzymes thereof.
- Cells of the same species that are comparable may be cells that have not undergone manipulations such as recombination or modification.
- inactivation of a septum formation initiator protein may mean that the activity of the polypeptide encoding the septum formation initiator is removed.
- the microorganisms inactivate the activity of the diaphragm initiation factor protein to a degree sufficient to produce L-lysine.
- the inactivation may be caused by a recombinant method.
- the recombination method may comprise homologous recombination.
- the homologous recombination method may cause homologous recombination with a partial sequence of the gene and an endogenous gene in the microorganism when the vector including the partial sequence of the gene is transformed into the microorganism and cultured in the presence of a selection marker product.

- the endogenous gene in the microorganism is recombined by the homologous recombination, and only a recombinant including the marker among the recombinant genes may be selected by a selection marker.
- the homologous recombination method it is possible to obtain a microorganism of the genus Corynebacterium in which the endogenous NCBI grant No. NCg10936 gene is inactivated.
- inactivation of protein activity may be caused by deletion, substitution, addition, reversal, or combination of bases, nucleosides, nucleotides, or a combination thereof.
- the method of inactivating protein activity may use, for example, a gene knockout approach, an antisense technique, or an RNAi technique. It may also include a method of deleting the initial copy of each gene, replacing the initial copy with a mutant, or expressing the initial copy from a weak promoter. It is also possible to substitute a promoter of a gene encoding the protein, introduce a mutation by random or target mutagenesis, or destroy or knock out the gene. It may also include a method of introducing a destabilizing element into an mRNA or introducing a genetic modification to alter the ribosomal binding site (RBS) of RNA.
- RBS ribosomal binding site
- Inactivation of the gene can be achieved by transforming a vector comprising a portion of the NCBI Grant No. NCg10936 gene and a selection marker to a microorganism of the genus Corynebacterium and culturing in the presence of antibiotics for selection.
- the selection marker may be implemented to select cells transformed with the vector.
- the selection marker may be a marker that confers a selectable phenotype, such as drug resistance, nutritional requirements, resistance to cytotoxic agents or expression of surface proteins.

- the ability of the microorganism to produce L-lysine can be improved.
- Example 1 ftsB gene inactivation recombinant vector construction by deletion
- the nucleotide sequence of the ftsB gene was obtained based on the nucleotide sequence reported to the National Institutes of Health (NIH Genbank) (SEQ ID NO: 2).
- Primers 0936F1, 09369R1, 0936F2, and 0936R2 were prepared based on SEQ ID NO: 2, respectively, to generate a gene fragment in which the open reading frame of ftsB was lost internally. Indicated.
- pDZ vector (see Korean Patent No. 0924065) was used to prepare an inactivated recombinant vector by ftsB gene deletion, and thereafter, a nucleic acid molecule having a modified sequence of ftsB gene, which was produced to be inactivated as described above.
- a vector pDZ- ⁇ ftsB vector comprising the nucleic acid sequence of SEQ ID NO: 4.
- the nucleic acid sequence of SEQ ID NO: 4 encodes an amino acid having the amino acid sequence of SEQ ID NO: 3.
- PCR was performed using primers 0936F1-0936R1 and 0936F2-0936R2 with Corynebacterium glutamicum ATCC13032 genomic DNA as a template.
- the polymerase was PfuUltraTM high-trust DNA polymerase (Stratagene), and PCR conditions were denatured 96 ° C., 30 seconds; Annealing 53 ° C., 30 seconds; And 30 degreeC of the polymerization reaction 72 degreeC and 2 minutes was repeated.
- pDZ- ⁇ ftsB includes both ends of XbaI of 135 bp ftsB and includes fragments in which 408 bp of the internal gene of ftsB is lost.
- the pDZ vector was used to construct a ftsB gene inactivation recombinant vector by introducing a stop codon mutation.
- a primer was prepared to replace the 140-th amino acid tryptophan counterpart codon in the gene open reading frame with a stop codon.
- the primers paired with 0936 F1 and 0936 R3 and primers paired with 0936 F3 and 0936 R2 were amplified by PCR in the same manner as in Example 1, and conjugated to the pDZ vector to prepare a vector pDZ-ftsB W140 *.
- the sequences of the 0936F3 and 0936R3 primers are represented by SEQ ID NOs: 11 and 12, respectively.
- the amino acid of the fts gene conjugated to the production vector has a sequence of SEQ ID NO: 5, and the nucleic acid has a nucleotide sequence of SEQ ID NO: 6.
- the primary chromosome-inserted strain was shaken in nutrient medium (30 ° C., 8 hours), and then diluted from 10 ⁇ 4 to 10 ⁇ 10 , respectively, and plated on a solid medium containing X-gal. While most colonies showed blue color, white colonies appearing at a low rate, so that the strains in which ftsB gene was inactivated by the second crossover were selected.
- PCR was performed using 0936F1-0936R2 of SEQ ID NO: 7 and SEQ ID NO: 10 as a primer to select ftsB gene inactivation mutants due to deletion. Finally, KCCM11016P- ⁇ ftsB was inactivated by the deletion of the ftsB gene.
- PCR was performed using primers paired with 0936F1-0936R2 of SEQ ID NO: 7 and SEQ ID NO: 10 to select the ftsB gene inactivating mutant strain by introducing stop codon mutations.
- Final identification of the target site by sequencing the ftsB gene inactivation mutant strain by introduction of the stop codon mutation KCCM11016P-ftsB W140 * was produced.
- Corynebacterium glutamicum KCCM11016P-ftsB W140 *, KCCM10770P-ftsB W140 *, KCCM10770P-ftsB W140 *, KCCM11347P-ftftsB, KCCM11 W140 * , CJ3P-ftftsB, and CJ3P-ftsB W140 * were incubated in the following manner for L-lysine production.
- Each of the cultured 1 ml seed cultures was then inoculated in a 250 ml corner-baffle flask containing 24 ml of the following production medium and shaken at 200 rpm for 120 hours at 30 ° C.
- the composition of the seed medium and the production medium is as follows.
- the lysine production was increased by about 4% in all cases where the ftsB gene was deleted or the stop codon was introduced from the parent strain KCCM11016P.
- the lysine concentration increased not by the structural change of the ftsB gene itself but by the deletion of the FtsB protein, which is a diaphragm initiation factor.
- the FtsB-inactivated strains increased the average lysine concentration by 4% compared to the wild-type FtsB-activated strains.
- KCCM11016P-ftsB W140 * (CA01-2274) was deposited on September 27, 2013 at the Korea Microorganism Conservation Center (Yurim Building, Hongje 1-dong, Seodaemun-gu, Seoul, Korea) under the accession number KCCM11454P.
