Functioni

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

Catalytic activityi

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

Cofactori

Cu2+By similarityNote: Binds 2 copper ions per subunit.By similarity

Enzyme regulationi

Activated by acidifying treatment at pH 3.0.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
