Ovaj enzim je flavoprotein. Postoji širok spektar monooksigenaza koje mogu da deluju na znatno različite suptrate, kao što su hidrazini, fosfini, jedinjenja bora, sulfidi, selenidi, jodidi, kao i primarni, sekundarni i tercijarni amini. Ovaj enzim se razlikuje od drugih monooksigenaza po tome što formira relativno stabilne hidroperoksi flavinske intermedijere.
