Mijeloperoksidaza (EC 1.11.2.2, MPO, verdoperoksidaza) je enzim sa sistematskim imenom hlorid:vodonik-peroksid oksidoreduktaza (formira hipohlorit).[1][2][3][4][5][6][7] Ovaj enzim katalizuje sledeću hemijsku reakciju
- Cl- + H2O2 + H+ HClO + H2O
Ovaj enzim sadrži kalcijum i kovalentno vezani hem. On je presutan u fagozomima neutrofila i monocita, gde je formirani hipohlorit veoma baktericidan.
