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 -!- FUNCTION: Catalyzes the ATP-dependent conversion of 5-aminoimidazole
CC ribonucleotide (AIR) and HCO(3)- to N5-carboxyaminoimidazole
