Abstract
A mutant bacterial acetolactate synthase (AHAS I) which is resistant to feedback inhibition by L-valine is described. Also described is a method for producing branched-chain L-amino acids using a bacterium from the Enterobacteriaceae family wherein the L-amino acid productivity of said bacterium is enhanced by the use of the acetolactate synthase (AHAS I) which is resistant to feedback inhibition by L-valine. This acetolactate synthase contains a mutant small subunit encoded by the mutant ilvN gene.
