Microorganism expressing 6-phosphogluconolactonase and its use in the production of L-amino acids.

摘要

A method for producing L-amino acids, such as L-tryptophan, L-phenylalanine, and L-tyrosine, using a bacterium of the Enterobacteriaceae family is provided. The L-amino acid productivity of said bacterium is increased by enhancing an activity of 6-phosphogluconolactonase, which is encoded by the pgl gene (ybhE ORF).
