Gluconate repressor variant, microorganism containing the same producing L-lysine, and method for producing L-lysine
The present invention relates to a novel gluconate repressor variant, a microorganism containing the same, and a method for producing L-lysine using the same.
1. An isolated and/or recombinant polypeptide having gluconate repressor activity comprising the amino acid sequence of SEQ ID NO: 1.
2. An isolated and/or recombinant polynucleotide encoding the polypeptide of claim 1 .
3. The isolated and/or recombinant polynucleotide of claim 2 , wherein the polynucleotide comprises the nucleotide sequence of SEQ ID NO: 2.
4. An expression vector comprising the polynucleotide of claim 2 .
5. A microorganism of the genus Corynebacterium producing L-lysine, expressing the polypeptide of claim 1 .
6. The microorganism of the genus Corynebacterium of claim 5 , wherein the microorganism of the genus Corynebacterium is Corynebacterium glutamicum.
7. A method for producing L-lysine, comprising
(a) culturing the microorganism of the genus Corynebacterium of claim 5 in a medium; and
(b) recovering L-lysine from the cultured microorganism or the medium in step (a).
8. A method for producing L-lysine, comprising
(a) culturing the microorganism of the genus Corynebacterium of claim 6 in a medium; and
(b) recovering L-lysine from the cultured microorganism or the medium in step (a).
