CC   -!- FUNCTION: This is a copper-containing oxidase that functions in
CC       the formation of pigments such as melanins and other polyphenolic
CC       compounds. Catalyzes the rate-limiting conversions of tyrosine to
CC       DOPA, DOPA to DOPA-quinone and possibly 5,6-dihydroxyindole to
CC       indole-5,6 quinone.
CC   -!- CATALYTIC ACTIVITY: L-tyrosine + L-dopa + O(2) = L-dopa +
CC       dopaquinone + H(2)O.
CC   -!- COFACTOR: Binds 2 copper ions per subunit.
CC   -!- SUBCELLULAR LOCATION: Melanosome membrane; Single-pass type I
CC       membrane protein.
CC   -!- SIMILARITY: Belongs to the tyrosinase family.
