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 alanine being the amino acid corresponding to position 321 of SEQ ID NO: 3 is replaced by valine. Also proposed are the following: a polynucleotide encoding the specified polypeptide, the microorganism Corynebacterium glutamicum, which produces L-lysine and contains the specified polypeptide or polynucleotide encoding the specified polypeptide, and a method for producing of L-lysine.
EFFECT: increasing the yield of L-lysine.
