Protein

Phenoloxidase subunit 1

Gene
N/A
Organism
Simulium damnosum (Black fly)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at transcript leveli

Functioni

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.Curated

Catalytic activityi

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

Cofactori
