FIELD: biotechnology.
SUBSTANCE: polypeptide is proposed that is involved in the production of L-lysine, consisting of the amino acid sequence represented by SEQ ID NO: 1, in which isoleucine being the amino acid corresponding to position 307 of SEQ ID NO: 3 is replaced by valine. Also proposed are the following: a polynucleotide encoding the said polypeptide, a microorganism Corynebacterium glutamicum producing L-lysine and containing the said polypeptide or polynucleotide encoding the said polypeptide, and a method for producing of L-lysine.
EFFECT: increasing the yield of L-lysine.
