General annotation (Comments)

Function

This is a copper-containing oxidase that functions in the formation of pigments such as melanins and other polyphenolic compounds. Catalyzes the rate-limiting conversions of tyrosine to DOPA, DOPA to DOPA-quinone and possibly 5,6 dihydroxyindole to indole-5'6 quinone.

Catalytic activity

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

L-tyrosine + O2 = dopaquinone + H2O.

Cofactor

Binds 2 copper ions per subunit By similarity. UniProtKB Q27451

Subunit structure

Heterodimer By similarity. UniProtKB Q27451

Subcellular location

Secreted By similarity.

Induction

By infection with O.dukei and O.ochengi. Ref.1

Sequence similarities

Belongs to the tyrosinase family.
