A PF02436 PYC_OADA Conserved carboxylase domain Family
A PF02785 Biotin_carb_C Biotin carboxylase C-terminal domain 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. PFAM PF02785
A PF00289 CPSase_L_chain Carbamoyl-phosphate synthase L chain, N-terminal domain Domain 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. PFAM PF00289
A PF00682 HMGL-like HMGL-like Family
A PF00364 Biotin_lipoyl Biotin-requiring enzyme Domain This family covers two Prosite entries, the conserved lysine residue binds biotin in one group and lipoic acid in the other. Note that the HMM does not currently recognise the Glycine cleavage system H proteins. PFAM PF00364
A PF02786 CPSase_L_D2 Carbamoyl-phosphate synthase L chain, ATP binding domain Domain 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. PFAM PF02786
