| Enzyme Function | FUNCTION: This is a copper-containing oxidase that functions in the formation of pigments such as melanins and other polyphenolic compounds (Probable). Catalyzes the oxidation of o-diphenols such as dopamine (PubMed:26732497). Also oxidizes monophenols such as tyramine (PubMed:26732497). {ECO:0000269|PubMed:26732497, ECO:0000305|PubMed:26732497}. |
