Peptidilprolilna izomeraza (EC 5.2.1.8, PPIaza, ciklofilin, peptid vezana izomeraza, peptidilna-prolil cis-trans izomeraza) je enzim sa sistematskim imenom peptidilprolin cis-trans-izomeraza.[1][2][3][4][5][6][7][8] Ovaj enzim katalizuje sledeću hemijsku reakciju

peptidilnaprolin (omega = 180) peptidilnaprolin (omega = 0)

Prvi pronađeni tip ovog enzima je proteinski ciklofilin, koji vezuje imunosupresant ciklosporin A. Postoje druge distinktne familije. Među njima su FK-506 vezujući proteini (FKBP).
