AAK_CK: Carbamate kinase (CK) catalyzes both the ATP-phosphorylation of carbamate and carbamoyl phosphate (CP) utilization with the production of ATP from ADP and CP. Both CK (this CD) and nonhomologous CP synthetase synthesize carbamoyl phosphate, an essential precursor of arginine and pyrimidine bases, in the presence of ATP, bicarbonate, and ammonia. CK is a homodimer of 33 kDa subunits and is a member of the Amino Acid Kinase Superfamily (AAK).
