DNA coding for a protein which imparts L-homoserine resistance to Escherichia coli bacterium, and a method for producing L-amino acids

摘要

A bacterium which has an ability to produce an amino acid and in which a novel rhtB gene encodes a protein having an activity of making a bacterium having the protein L-homoserine-resistant is enhanced, is cultivated in a culture medium to produce and cause accumulation of the amino acid in the medium, and the amino acid is recovered from the medium.
