FIELD: biotechnology.
SUBSTANCE: invention relates to biotechnology and is a polypeptide involved in the production of L-amino acids in which lysine, which is an amino acid corresponding to position 415 in the amino acid sequence SEQ ID NO: 1, is replaced by histidine, where the polypeptide has a sequence identity of 80% or more with the amino acid sequence SEQ ID NO: 1. The invention also relates to a method for producing L-amino acids using a microorganism transformed by a polynucleotide encoding the specified peptide.
EFFECT: invention makes it possible to obtain L-amino acids with a high degree of efficiency.
