FIELD: chemistry; biochemistry. ^ SUBSTANCE: invention relates to biochemistry. The invention is a method of producing L-amino acid using bacteria of the Escherichia family, which is modified so that, it contains glycerin kinase, in which there is weak inhibition of fructose-1,6-diphosphate according to feedback type, and the said glycerin kinase contains substitution of at least one amino acid with another in the region which corresponds to positions from 233 to 235 in the amino acid sequence of glycerin kinase of another type, presented in SEQ ID NO:4. ^ EFFECT: obtaining highly effective L-amino acid. ^ 12 cl, 3 dwg, 4 tbl, 16 ex |
