  • Mutant acetolactate synthase and a method for producing branched-chain L-amino acids
    Patent number: 9279137
    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.
    Type: Grant
    Filed: July 17, 2014
    Date of Patent: March 8, 2016
    Assignee: AJINOMOTO CO., INC.
