Carbamoylphosphate synthetase and method for producing compounds derived from carbamoylphosphate

摘要

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.
