CC -!- FUNCTION: Catalyzes the conversion of N5-carboxyaminoimidazole CC ribonucleotide (N5-CAIR) to 4-carboxy-5-aminoimidazole CC ribonucleotide (CAIR). {ECO:0000256|HAMAP-Rule:MF_01929}. CC -!- CATALYTIC ACTIVITY: 5-carboxyamino-1-(5-phospho-D- CC ribosyl)imidazole = 5-amino-1-(5-phospho-D-ribosyl)imidazole-4- CC carboxylate. {ECO:0000256|HAMAP-Rule:MF_01929}. CC -!- PATHWAY: Purine metabolism; IMP biosynthesis via de novo pathway; CC 5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxylate from 5- CC amino-1-(5-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 CC subfamily. {ECO:0000256|HAMAP-Rule:MF_01929}. CC -!- CAUTION: The sequence shown here is derived from an CC EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is CC preliminary data. {ECO:0000313|EMBL:ELC91661.1}.
