Protein attributes

Sequence length	162 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

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.
Subunit structure	Homooctamer By similarity.
Sequence similarities	Belongs to the AIR carboxylase family.
