FIELD: biotechnology.
SUBSTANCE: invention is a polypeptide involved in the production of L-valine, consisting of the amino acid sequence represented by SEQ ID NO: 1 in which glycine being the amino acid corresponding to position 834 of SEQ ID NO: 3 is replaced by serine. The invention also relates to a method for the production of L-valine, which includes cultivating in a medium a microorganism Corynebacterium glutamicum containing a polypeptide according to the invention, or a polynucleotide encoding this polypeptide.
EFFECT: obtaining L-valine with a high degree of efficiency.
