Abstract:
1. An isolated L-amino acid producing bacterium belonging to the genus Eseherichia , wherein the bacterium has increased expression of a gene encoding a protein selected from the group consisting of: (A) a protein comprising the amino acid sequence in SEQ ID NO: 4; and (B) a protein comprising the amino acid sequence of SEQ ID NO: 4 except that a total of between 1 and 5 amino acids are deleted, substituted, inserted, or added, and wherein said protein imparts to the bacterium increased resistance to L-amino acids and/or analogs thereof; and, in addition, increased expression of a gene encoding a protein selected from the group consisting of: (C) a protein comprising the amino acid sequence in SEQ ID NO: 6 , and (D) a protein comprising the amino acid sequence of SEQ ID NO:6 except that a total of between 1 and 5 amino acids are deleted, substituted, inserted, or added, and wherein said protein imparts to the bacterium enhanced resistance to L-amino acids and/or analogs thereof, wherein the expression of said proteins is increased by transforming said bacterium with the gene coding for said protein, or by placing said gene under the control of a potent promoter.
