Function
function
Catalyzes the ATP-dependent conversion of 5-aminoimidazole ribonucleotide (AIR) and HCO3- to N5-carboxyaminoimidazole ribonucleotide (N5-CAIR).
Catalyzes the ATP-dependent conversion of 5-aminoimidazole ribonucleotide (AIR) and HCO3- to N5-carboxyaminoimidazole ribonucleotide (N5-CAIR).
Catalytic activity
- 5-amino-1-(5-phospho-beta-D-ribosyl)imidazole + hydrogencarbonate + ATP = 5-carboxyamino-1-(5-phospho-D-ribosyl)imidazole + ADP + phosphate + 2 H+
Pathway
Purine metabolism; IMP biosynthesis via de novo pathway; 5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxylate from 5-amino-1-(5-phospho-D-ribosyl)imidazole (N5-CAIR route): step 1/2.
