Gamma-aminobutyrate permeazine variant, polynucleotides, vectors, microorganisms, by-product reduction methods, l-isoleuxin production preparations, and methods for producing l-isoleuxin using these variants

Abstract

The invention relates to a novel permcase γ-aminohydrochloride variant that reduces the amount of byproducts generated during the production of L-isoleucine, the polynucleotide encoding the variant, and the vector containing the microbial polynucleotide including the variant, polynucleotide or vector, the method of L-isoleucine production using microorganisms, the method of reducing the amount of byproducts generated during L-isoleucine production, and the L-isoleucine production product.
