Fosforibozilaminoimidazolna karboksilaza (EC 4.1.1.21, 5-fosforibozil-5-aminoimidazolna karboksilaza, 5-amino-1-ribozilimidazol 5-fosfatna karboksilaza, AIR karboksilaza, 1-(5-fosforibozil)-5-amino-4-imidazolkarboksilatna karboksi-lijaza, ADE2, klasa II PurE, 5-amino-1-(5-fosfo-D-ribozil)imidazol-4-karboksilatna karboksi-lijaza) je enzim sa sistematskim imenom 5-amino-1-(5-fosfo-D-ribozil)imidazol-4-karboksilat karboksi-lijaza (formira 5-amino-1-(5-fosfo-D-ribozil)imidazol).[1][2][3] Ovaj enzim katalizuje sledeću hemijsku reakciju
- 5-amino-1-(5-fosfo-D-ribozil)imidazol-4-karboksilat 5-amino-1-(5-fosfo-D-ribozil)imidazol + CO2
Ova reakcija se odvija u kičmenjacima tokom purinske biosinteza.
