CC -!- FUNCTION: Catalyzes the conversion of N5-carboxyaminoimidazole
CC ribonucleotide (N5-CAIR) to 4-carboxy-5-aminoimidazole ribonucleotide
CC (CAIR). {ECO:0000256|HAMAP-Rule:MF_01929}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=5-carboxyamino-1-(5-phospho-D-ribosyl)imidazole + H(+) = 5-
CC amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxylate;
CC Xref=Rhea:RHEA:13193, ChEBI:CHEBI:15378, ChEBI:CHEBI:58730,
CC ChEBI:CHEBI:77657; EC=5.4.99.18; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_01929};
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 2/2.
CC {ECO:0000256|HAMAP-Rule:MF_01929}.
CC -!- SIMILARITY: Belongs to the AIR carboxylase family. Class I subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_01929}.
