  • Mutant carbamoylphosphate synthetase and method for producing compounds derived from carbamoylphosphate
    Patent number: 7211419
    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: Grant
    Filed: October 20, 2005
    Date of Patent: May 1, 2007
    Assignee: Ajinomoto Co., Inc.
    Inventors: Leonid Romanovich Ptitsyn, Sergey Vasil'evich Smirnov, Irina Borisovna Altman, Anna Eugenievna Novikova, Veronika Aleksandrovna Kotliarova, Mikhail Markovich Gusyatiner, Yulia Georgievna Rostova, Tatyana Abramovna Yampolskaya
