Bromid peroksidaza (EC 1.11.1.18, bromoperoksidaza, haloperoksidaza (nespecifična), eozinofilna peroksidaza) je enzim sa sistematskim imenom bromid:vodonik-peroksid oksidoreduktaza.[1][2][3][4][5] Ovaj enzim katalizuje sledeću hemijsku reakciju:
- RH + HBr + H2O2 RBr + 2H2O
Ove bromoperoksidaze crvenih i smeđih morskih algi (Rhodophyta i Phaeophyta) sadrže vanadat. One katalizuju brominaciju niza organskih molekula kao što su seskviterpeni, formirajući stabilne C-Br veze. Bromoperoksidaze takođe oksiduju jodide.
