1. A method for producing an L-amino acid comprising:

(i) cultivating an L-amino acid-producing bacterium of the family Enterobacteriaceae in a culture medium to produce the L-amino acid in the culture medium, the bacterium, or both; and

(ii) collecting said L-amino acid from the culture medium, the bacterium, or both, wherein said bacterium has been modified to attenuate expression of a gshA gene, and wherein said L-amino acid is a branched-chain L-amino acid.
