FUNCTION: This is a copper-containing oxidase that functions in the formation of pigments such as melanins and other polyphenolic compounds.
CATALYTIC ACTIVITY: L-tyrosine + L-dopa + O₂ = L-dopa + dopaquinone + H₂O.
COFACTOR: Binds 2 copper ions per subunit (By similarity).
SIMILARITY: Belongs to the tyrosinase family.
