GENE DNA CODING ACETOHYDROXY ACID ISOMEROREDUCTASE

摘要

PURPOSE:To produce L-isoleucine or L-valine in high efficiency by using a gene originated from coryneform bacteria and coding acetohydroxy acid isomeroreductase. CONSTITUTION:A gene coding acetohydroxy acid isomeroreductase and consisting of 1014 base pairs coding 338 amino acids is separated from Brevibacterium flavum MJ-233 and introduced into the same kind of coryneform bacteria. L-isoleucine or L-valine can be produced in high efficiency from a new viewpoint by using the transformed coryneform bacteria.
