General annotation (Comments)

Function

This is a copper-containing oxidase that functions in the formation of pigments such as melanins and other polyphenolic compounds.

Catalytic activity

2 L-dopa + O2 = 2 dopaquinone + 2 H2O.

L-tyrosine + O2 = dopaquinone + H2O.

Cofactor

Binds 2 copper ions per subunit.

Subcellular location

Melanosome membrane; Single-pass type I membrane protein.

Sequence similarities

Belongs to the tyrosinase family.
