Nespecifična monooksigenaza (EC 1.14.14.1, microsomal monooksigenaza, ksenobiotik monooksigenaza, aril-4-monooksigenaza, aril hidrokarbon hidroksilaza, microsomal P-450, flavoprotein-vezani monooksigenaza, flavoprotein monooksigenaza) je enzim sa sistematskim imenom supstrat,redukovani-flavoprotein:kiseonik oksidoreduktaza (RH-hidroksilacija or -epoksidacija).[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] Ovaj enzim katalizuje sledeću hemijsku reakciju
- RH + redukovani flavoprotein + O2 ROH + oksidovani flavoprotein + H2O
Nespecifična monooksigenaza je grupa hem-tiolatnih proteina (P-450), koji deluju na širok opseg supstrata uključujući mnoge ksenobiotike, steroide, masne kiseline, vitamine i prostaglandine.
