This domain composes the whole protein of methylglyoxal synthetase and the domain is also found in Carbamoyl phosphate synthetase (CPS) where it forms a regulatory domain that binds to the allosteric effector ornithine.

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
