  • Mutant N-acetylglutamate synthase and method for L-arginine production
    Publication number: 20030148475
    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.
    Type: Application
    Filed: June 22, 2001
    Publication date: August 7, 2003
    Applicant: AJINOMOTO CO., INC.
    Inventors: Leonid Romanovich Ptitsyn, Irina Borisovna Altman, Sergey Vasil?apos;evich Smirnov, Yulia Georgievna Rostova, Tatyana Abramovna Yampolskaya, Tatyana Viktorovna Leonova, Mikhail Markovich Gusyatiner
  • Mutant carbamoylphosphate synthetase and method for producing compounds derived from carbamoylphosphate
    Publication number: 20030129708
    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.
