Title:
TRANSFORMANT OF CORYNEFORM BACTERIUM AND METHOD FOR PRODUCING VALINE BY USING SAME
Document Type and Number:
WIPO Patent Application WO/2013/027709
Kind Code:
A1
Abstract:
This transformant is obtained by introducing, to a host coryneform bacterium, at least one of the DNAs (a), (b), and (c): (a) a DNA, or an analog thereof, obtained by introducing, to a DNA that encodes an acetohydroxy acid synthase derived from Corynebacterium glutamicum, a mutation that mutates the No. 156 glycine in the amino acid sequence encoded by this DNA to glutamic acid (G156E); (b) a DNA, or an analog thereof, obtained by introducing, to a DNA that encodes an acetohydroxy acid isomeroreductase derived from Corynebacterium glutamicum, mutations that mutate the No. 34 serine in the amino acid sequence encoded by this DNA to glycine (S34G), mutate the No. 48 leucine to glutamic acid (L48E), and mutate the No. 49 arginine to phenylalanine (R49F); and (c) a DNA, or an analog thereof, that encodes a leucine dehydrogenase derived from Lysinibacillus sphaericus.
