CC -!- FUNCTION: This is a copper-containing oxidase that functions in the
CC formation of pigments such as melanins and other polyphenolic
CC compounds. Catalyzes the rate-limiting conversions of tyrosine to DOPA,
CC DOPA to DOPA-quinone and possibly 5,6 dihydroxyindole to indole-5'6
CC quinone. {ECO:0000305}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 L-dopa + O2 = 2 H2O + 2 L-dopaquinone; Xref=Rhea:RHEA:34287,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15379, ChEBI:CHEBI:57504,
CC ChEBI:CHEBI:57924; EC=1.14.18.1;
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-tyrosine + O2 = H2O + L-dopaquinone; Xref=Rhea:RHEA:18117,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15379, ChEBI:CHEBI:57924,
CC ChEBI:CHEBI:58315; EC=1.14.18.1;
CC -!- COFACTOR:
CC Name=Cu(2+); Xref=ChEBI:CHEBI:29036;
CC Evidence={ECO:0000250|UniProtKB:Q27451};
CC Note=Binds 2 copper ions per subunit. {ECO:0000250|UniProtKB:Q27451};
CC -!- SUBUNIT: Heterodimer. {ECO:0000250|UniProtKB:Q27451}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC -!- INDUCTION: By infection with O.dukei and O.ochengi.
CC {ECO:0000269|PubMed:9225772}.
CC -!- SIMILARITY: Belongs to the tyrosinase family. {ECO:0000255}.
