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

Chains	Enzyme Name	Description	Catalytic Residues
A	pyruvate carboxylase M-CSA #223	Pyruvate carboxylase, isolated from Rhizobium etli, is a biotin-dependent enzyme. It catalyses the carboxylation of pyruvate to oxaloacetate using bicarbonate and coupled to the hydrolysis of ATP to ADP and phosphate. This reaction occurs in two major steps: the carboxylation of biotin by ATP and bicarbonate in the biotin carboxylase (BC) domain, and the carboxylation of pyruvate in the carboxyltransferase (CT) domain. The biotin is bound to the biotin carboxyl carrier protein (BCCP) domain, which moves between the BC domain of one subunit and the CT domain of a neighbouring subunit.
