Phosphoribosylaminoimidazole-succinocarboxamide synthase (EC:6.3.2.6) (SAICAR synthetase) catalyses the seventh step in the de novo purine biosynthetic pathway; the ATP-dependent conversion of 5'-phosphoribosyl-5-aminoimidazole-4-carboxylic acid and aspartic acid to SAICAR [1]. This domain can be found in SAICAR synthetases as a monofunctional protein from the bacteria (purC), fungi (ADE1) and plants (Pur7). In animals, this domain can be found in the N-terminal domain of a multifunctional enzyme (ADE2) possessing both the SAICAR synthetase and the phosphoribosylaminoimidazole carboxylase (AIR carboxylase) activity.	Domain
A, B	PF00731	AIR carboxylase (AIRC)	AIR carboxylase	Members of this family catalyse the decarboxylation of 1-(5-phosphoribosyl)-5-amino-4-imidazole-carboxylate (AIR). This family catalyse the sixth step of de novo purine biosynthesis. Some members of this family contain two copies of this domain.	Domain
