  • Carbamoylphosphate synthetase and method for producing compounds derived from carbamoylphosphate
    Publication number: 20060035343
    Abstract: L-arginine, citrulline and pyrimidine derivatives including orotic acid, uridine, uridine 5?-monophosphate (UMP), cytidine and cytidine. 5?-monophosphate (CMP) are produced using a bacterium belonging to the genus Escherichia harboring a mutant carbamoylphosphate synthetase in which the amino acid sequence corresponding to positions from 947 to 951 in a wild type carbamoylphosphate synthetase is replaced with any one of amino acid sequences of SEQ ID NOS: 1 to 9, and feedback inhibition by uridine 5?-monophosphate in the bacterium is desensitized.
    Type: Application
    Filed: October 20, 2005
    Publication date: February 16, 2006
    Applicant: AJINOMOTO CO., INC
    Inventors: Leonid Ptitsyn, Sergey Smirnov, Irina Altman, Anna Novikova, Veronika Kotliarova, Mikhail Gusyatiner, Yulia Rostova, Tatyana Yampolskaya
  • Mutant glutamine synthetase and method for producing amino acids
    Publication number: 20050255567
    Abstract: Amino acids, such as L-glutamine, L-arginine, L-tryptophan, L-histidine and L-glutamate are produced using a bacterium belonging to the genus Escherichia harboring a mutant glutamine synthetase in which the tyrosine amino acid residue corresponding to position 397 in a wild type glutamine synthetase is replaced with any of amino acid residues, preferably with phenylalanine.

  • Mutant N-acetylglutamate synthase and method for L-arginine production
    Publication number: 20050026258
    Abstract: L-arginine is produced using a bacterium belonging to the genus Escherichia harboring a mutant N-acetylglutamate synthase in which the amino acid sequence corresponding to positions from 15 to 19 in a wild type N-acetylglutamate synthase is replaced with any one of amino acid sequences of SEQ ID NOS: 1 to 4, and feedback inhibition by L-arginine is desensitized.
