摘要:
There is provided a method for producing L-threonine, L-valine, L-proline, L-leucine, L-methionine and L-arginine using a bacterium belonging to the genus Escherichia wherein the L-amino acid productivity of the bacterium is enhanced by enhancing the activities of the proteins coded by the b2682 and b2683 genes, or the protein coded by the b1242 or b3434 gene.
