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       ECO:0000256|PIRNR:PIRNR001338}.
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, ECO:0000256|PIRNR:PIRNR001338};
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, ECO:0000256|PIRNR:PIRNR001338}.
CC   -!- SIMILARITY: Belongs to the AIR carboxylase family. Class I subfamily.
CC       {ECO:0000256|HAMAP-Rule:MF_01929}.
CC   -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC       whole genome shotgun (WGS) entry which is preliminary data.
