Abstract

The present disclosure relates to a microorganism of the genus Corynebacterium producing L-amino acid, a method for producing L-amino acid using the same, use of L-amino acid production, and a composition for producing L-amino acid.

Claims (11)

1 . A microorganism producing L-amino acid, in which the activity of glucose-6-phosphate 1-dehydrogenase and fructokinase is enhanced.

2 . The microorganism of claim 1 , wherein the glucose-6-phosphate 1-dehydrogenase comprises an amino acid sequence comprising a sequence identity of at least 80% to SEQ ID NO: 1 or SEQ ID NO: 3.

3 . The microorganism of claim 1 , wherein the fructokinase comprises an amino acid sequence comprising a sequence identity of at least 80% to SEQ ID NO: 5.

4 . The microorganism of claim 1 , wherein the L-amino acid is L-lysine or L-tryptophan.

5 . A method for producing L-amino acid, comprising: culturing the microorganism of claim 1 in a medium; and recovering the L-amino acid from the microorganism or medium.

6 . The method of claim 5 , wherein the L-amino acid is L-lysine or L-tryptophan.

7 . A composition for producing L-amino acid, comprising the microorganism of claim 1 or a culture of the microorganism.

8 . The microorganism of claim 1 , wherein the microorganism is genus of Corynebacterium.

9 . The microorganism of claim 8 , wherein the genus of Corynebacterium is Corynebacterium glutamicum.

10 . The microorganism of claim 5 , wherein the microorganism is genus of Corynebacterium.

11 . The microorganism of claim 10 , wherein the genus of Corynebacterium is Corynebacterium glutamicum.
