DNA coding for mutant isopropylmalate synthase, l-leucine-producing microorganism and method for producing l-leucine

A method for producing L-leucine, comprising the steps of: culturing a bacterium which is transformed with a DNA coding for an alpha -isopropylmalate synthase densensitized in feedback inhibition by L-leucine, in a culture medium to produce and accumulate L-leucine in the medium, and recovering L-le...
