Masna-kiselina peroksigenaza (EC 1.11.2.4, masno kiselinska hidroksilaza (nespecifična), P450 peroksigenaza, CYP152A1, P450BS, P450SPalfa) je enzim sa sistematskim imenom masna kiselina:hidroperoksid oksidoreduktaza (RH-hidroksilacija).[1][2][3][4][5][6][7][8] Ovaj enzim katalizuje sledeću hemijsku reakciju
- masna kiselina + H2O2 3- ili 2-hidroksi masna kiselina + H2O
Ovaj citosolni hem-tiolatni protein je sekventno homologan sa P450 monooksigenazama. Za njegov rad nisu neophodni NAD(P)H, dioksigen i specifične reduktaze. Enzime ovog tipa formiraju bakterije (e.g. Sphingomonas paucimobilis, Bacillus subtilis).
