Cytochrome P450 monooxygenase that is able to use anthracene, carbazole, pyrene, and phenanthrene as substrates for oxidation (PubMed:21938516). These multifunctional properties against a series of polycyclic aromatic hydrocarbons (PAHs) suggest that CYP231 would play important roles, at least in part, in fungal metabolic systems involved in xenobiotic detoxification (Probable). Secondary metabolite biosynthesis. Belongs to the cytochrome P450 family.
