Carbamoyl-phosphate synthase catalyses the ATP-dependent synthesis of carbamyl-phosphate from glutamine or ammonia and bicarbonate. This important enzyme initiates both the urea cycle and the biosynthesis of arginine and/or pyrimidines [2]. The carbamoyl-phosphate synthase (CPS) enzyme in prokaryotes is a heterodimer of a small and large chain. The small chain promotes the hydrolysis of glutamine to ammonia, which is used by the large chain to synthesise carbamoyl phosphate. See Pfam:PF00988. The small chain has a GATase domain in the carboxyl terminus. See Pfam:PF00117. The ATP binding domain (this one) has an ATP-grasp fold.	Domain

This domain represents a conserved region in pyruvate carboxylase (PYC), oxaloacetate decarboxylase alpha chain (OADA), and transcarboxylase 5s subunit. The domain is found adjacent to the HMGL-like domain (Pfam:PF00682) and often close to the biotin_lipoyl domain (Pfam:PF00364) of biotin requiring enzymes.	Domain
