Method of producing L-amino acids

A method of producing a target L-amino acids, the method comprising

• culturing a recombinant coryneform microorganism in a medium, wherein the recombinant coryneform microorganism is capable of producing a target L-amino acid and is transformed by inserting an acetate-inducible promoter downstream of a stop codon of a target gene in a chromosome such that transcription from the acetate-inducible promoter occurs in a direction opposite to the direction of the target gene transcription, wherein the target gene is a gene located at a branch point of a biosynthetic pathway of the target L-amino acid and encoding an enzyme involved in byproduct production, wherein the target L-amino acid is L-threonine, L-methionine, L-isoleucine, L-lysine, L-alanine, or L-valine.
