CC -!- FUNCTION: Catalyzes the ATP-dependent conversion of 5-aminoimidazole
CC ribonucleotide (AIR) and HCO(3)(-) to N5-carboxyaminoimidazole
CC ribonucleotide (N5-CAIR). {ECO:0000256|HAMAP-Rule:MF_01928}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=5-amino-1-(5-phospho-beta-D-ribosyl)imidazole + ATP +
CC hydrogencarbonate = 5-carboxyamino-1-(5-phospho-D-ribosyl)imidazole +
CC ADP + 2 H(+) + phosphate; Xref=Rhea:RHEA:19317, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:17544, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474,

CC EC=6.3.4.18; Evidence={ECO:0000256|HAMAP-Rule:MF_01928};
CC -!- PATHWAY: Purine metabolism; IMP biosynthesis via de novo pathway; 5-
CC amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxylate from 5-amino-1-(5-
CC phospho-D-ribosyl)imidazole (N5-CAIR route): step 1/2.
CC {ECO:0000256|HAMAP-Rule:MF_01928}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01928}.
CC -!- SIMILARITY: Belongs to the PurK/PurT family. {ECO:0000256|HAMAP-
CC Rule:MF_01928}.
