General annotation (Comments)

Function	This subunit can alone transform AIR to CAIR, but in association with purK, which possesses an ATPase activity, an enzyme complex is produced which is capable of converting AIR to CAIR efficiently under physiological condition By similarity.
Catalytic activity	5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxylate = 5-amino-1-(5-phospho-D-ribosyl)imidazole + CO2.
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 (carboxylase route): step 1/1.
Sequence similarities	Belongs to the AIR carboxylase family.
