Claims13
A gluconate repressor variant, wherein one or more amino acids selected from the group consisting of an amino acid corresponding to position 36, an amino acid corresponding to position 59, an amino acid corresponding to position 60, an amino acid corresponding to position 63, an amino acid corresponding to position 79, and an amino acid corresponding to position 92 of an amino acid sequence of SEQ ID NO:
- 1 are substituted with different amino acids.
A microorganism of the genus Corynebacterium comprising a gluconate repressor variant having a substitution of an amino acid corresponding to position 70 of an amino acid sequence of SEQ ID NO:
- 1 with a different amino acid, or a polynucleotide encoding the variant, wherein the microorganism of the genus Corynebacterium has L-arginine-producing ability.
