CC   -!- FUNCTION: Catalyzes two reactions in de novo purine nucleotide
CC       biosynthesis. Catalyzes the breakdown of 5-aminoimidazole- (N-
CC       succinylocarboxamide) ribotide (SAICAR or 2-[5-amino-1-(5-phospho-beta-
CC       D-ribosyl)imidazole-4-carboxamido]succinate) to 5-aminoimidazole-4-
CC       carboxamide ribotide (AICAR or 5-amino-1-(5-phospho-beta-D-
CC       ribosyl)imidazole-4-carboxamide) and fumarate, and of adenylosuccinate
CC       (ADS or N(6)-(1,2-dicarboxyethyl)-AMP) to adenosine monophosphate (AMP)
CC       and fumarate. {ECO:0000250|UniProtKB:P0AB89}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=N(6)-(1,2-dicarboxyethyl)-AMP = AMP + fumarate;
CC         Xref=Rhea:RHEA:16853, ChEBI:CHEBI:29806, ChEBI:CHEBI:57567,

CC         Evidence={ECO:0000250|UniProtKB:P0AB89};
CC       PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:16854;
CC         Evidence={ECO:0000250|UniProtKB:P0AB89};
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(2S)-2-[5-amino-1-(5-phospho-beta-D-ribosyl)imidazole-4-
CC         carboxamido]succinate = 5-amino-1-(5-phospho-beta-D-
CC         ribosyl)imidazole-4-carboxamide + fumarate; Xref=Rhea:RHEA:23920,
CC         ChEBI:CHEBI:29806, ChEBI:CHEBI:58443, ChEBI:CHEBI:58475; EC=4.3.2.2;

CC         Evidence={ECO:0000250|UniProtKB:P0AB89};
CC   -!- PATHWAY: Purine metabolism; AMP biosynthesis via de novo pathway; AMP
CC       from IMP: step 2/2.
CC   -!- PATHWAY: Purine metabolism; IMP biosynthesis via de novo pathway; 5-
CC       amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide from 5-amino-1-(5-
CC       phospho-D-ribosyl)imidazole-4-carboxylate: step 2/2.
CC   -!- SUBUNIT: Homotetramer. Residues from neighboring subunits contribute
CC       catalytic and substrate-binding residues to each active site (By
CC       similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the lyase 1 family. Adenylosuccinate lyase
CC       subfamily. {ECO:0000305}.
