IUBMB Comments

A type 3 copper protein that catalyses exclusively the oxidation of catechol (i.e., o-diphenol) to the corresponding o-quinone. The enzyme also acts on a variety of substituted catechols. It is different from tyrosinase, EC 1.14.18.1, which can catalyse both the monooxygenation of monophenols and the oxidation of catechols.

The enzyme appears in viruses and cellular organisms
