Patent ID: 8187843

Claim:
A mutant microorganism belonging to the genus Corynebacterium , which has been formed by mutating a parental microorganism belonging to the genus Corynebacterium, wherein the mutant microorganism produces L-glutamine more efficiently than the parental microorganism, wherein the parental microorganism exhibits (a) the activity of (1) a protein having the amino acid sequence shown by any one of SEQ ID NO: 1 to 3, or (2) a protein having a homology of 95% or more to the amino acid sequence shown by any one of SEQ ID NO: 1 to 3, and having substantially the same activity as the activity of a protein having the amino acid sequence shown by any one of SEQ ID NO: 1 to 3, and (b) the activity of (3) a protein having the amino acid sequence shown by SEQ ID NO: 4, or (4) a protein having a homology of 95% or more to the amino acid sequence shown by SEQ ID NO: 4, and having substantially the same activity as the activity of a protein having the amino acid sequence shown by SEQ ID NO: 4, wherein a nucleotide deletion, substitution, or addition to the nucleotide sequence of an endogenous gene of the parental microorganism results in the reduction or loss of the protein activity (a), and wherein a nucleotide deletion, substitution, or addition to the nucleotide sequence of an endogenous gene of the parental microorganism results in the reduction or loss of the protein activity (b).
