Magnolizin (EC 3.4.24.62, prooksitocin/neurofizin konvertaza, prooksifizinska proteinaza, prooksitocinska konvertaza) je enzim.[1][2][3][4][5] Ovaj enzim katalizuje sledeću hemijsku reakciju
- Hidroliza polipeptida sa Arg ili Lys u P1 i P2, e.g. hidroliza prooksitocina u -Lys-Arg-Ala-Val-. Dalja specifičnos je zavisna od organizacije beta-zaokret-alfa-heliksa sa devet ili više ostataka koji sadrže parove baznih aminokiselina blizo centra
Ova endopeptidaza je prisutna u goveđoj hipofizi.
