Modified microorganism of genus Corynebacterium producing L-glutamic acid and method for producing L-glutamic acid using same

Abstract

The present invention relates to a Corynebacterium sp. mutant microorganism producing L-glutamic acid and a method of producing L-glutamic acid using the same, and more specifically, to a novel biotin-protein ligase variant involved in the L-glutamic acid biosynthetic pathway, a polynucleotide, and a transformant, as well as a method of producing L-glutamic acid using the same. The biotin-protein ligase variant according to the present invention is obtained by substituting one or more amino acids in the amino acid sequence constituting biotin-protein ligase to change the enzymatic activity of the biotin-protein ligase, and a recombinant microorganism comprising the biotin-protein ligase variant is capable of efficiently producing L-glutamic acid.
