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

Biotin carboxylase is a component of the acetyl-CoA carboxylase multi-component enzyme which catalyses the first committed step in fatty acid synthesis in animals, plants and bacteria. Most of the active site residues reported in reference [1] are in this C-terminal domain.	Domain
A, B, C, D	PF00289	Biotin carboxylase, N-terminal domain (Biotin_carb_N)	Biotin carboxylase, N-terminal domain	This domain is structurally related to the PreATP-grasp domain. The family contains the N-terminus of biotin carboxylase enzymes [1,3], and propionyl-CoA carboxylase A chain [2].	Domain
