RC STRAIN=Y51MC23 {ECO:0000313|EMBL:EED10905.1, RC ECO:0000313|Proteomes:UP000005403}; RG US DOE Joint Genome Institute (JGI-PGF); RA Lucas S., Copeland A., Lapidus A., Glavina del Rio T., Dalin E., RA Tice H., Bruce D., Goodwin L., Pitluck S., Larimer F., Land M.L., RA Hauser L., Saunders E., Tapia R., Green L., Rogers Y., Detter J.C., RA Brettin T.S., Mead D.; RT "Sequencing of the draft genome and assembly of Thermus aquaticus RT Y51MC23."; RL Submitted (DEC-2008) to the EMBL/GenBank/DDBJ databases. 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:EED10905.1}.
