A MICROORGANISM OF THE GENUS ESCHERICHIA HAVING ENHANCED L-TRYPTOPHAN PRODUCTIVITY AND A METHOD FOR PRODUCING L-TRYPTOPHAN USING THE SAME

摘要

The present invention relates to microorganisms ofEscherichia coli having enhanced L-tryptophan productivity andto a method for producing L-tryptophan using the same. Moreparticularly, the present invention relates to an Escherichiacoli variant in which repression and attenuation control of thetryptophan operon is released and accumulation of anthranilateis reduced and thereby enhancing L-tryptophan productivity. Thepresent invention also relates to a method for producingL-tryptophan using the Escherichia coli variant.
