FIELD: biotechnology.
SUBSTANCE: invention is a polypeptide involved in the production of L-lysine consisting of the amino acid sequence represented by SEQ ID NO 1, in which glutamic acid being the amino acid corresponding to position 259 in SEQ ID NO 3 is replaced by asparagine. The invention also relates to a method of the production of L-tryptophan that includes culturing in the environment of the microorganism Escherichia coli containing the specified polypeptide or polynucleotide encoding this polypeptide.
EFFECT: obtaining L-lysine with a high degree of efficiency.
