  • METHOD FOR PRODUCING L-AMINO ACID USING BACTERIA BELONGING TO THE GENUS ESCHERICHIA
    Publication number: 20080261279
    Abstract: A method for producing L-threonine, L-valine, L-proline, L-leucine, L-methionine and L-arginine is provided using Escherichia bacteria wherein the L-amino acid productivity of the bacteria is enhanced by increasing the activity of proteins encoded by the b2682 and b2683 genes, or proteins encoded by the b1242 or b3434 gene.

  • Method for producing L-leucine
    Patent number: 7220572
    Abstract: There is provided a method for producing L-leucine using bacterium belonging to the genus Escherichia, which produces L-valine, L-isoleucine and L-homoleucine in an amount of less than 1% of that of L-leucine produced due to inactivation of ilvE gene coding for branched chain amino acid transaminase and produces increased amount of L-leucine due to increasing the activity of the aromatic amino acid transaminase encoded by tyrB gene.

  • DNA coding for mutant isopropylmalate synthase L-leucine-producing microorganism and method for producing L-leucine
    Patent number: 6403342
    Abstract: A method for producing L-leucine, comprising the steps of: culturing a bacterium which is transformed with a DNA coding for an a-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-leucine from the medium.
