ID   1.10.3.1
DE   catechol oxidase.
AN   diphenol oxidase.
AN   o-diphenolase.
AN   phenolase.
AN   polyphenol oxidase.
AN   tyrosinase.
CA   2 catechol + O2 = 2 1,2-benzoquinone + 2 H2O.
CC   -!- A type 3 copper protein that catalyzes exclusively the oxidation of
CC       catechols (i.e., o-diphenols) to the corresponding o-quinones.
CC   -!- The enzyme also acts on a variety of substituted catechols.
CC   -!- It is different from tyrosinase, EC 1.14.18.1, which can catalyze
CC       both the monooxygenation of monophenols and the oxidation of
CC       catechols.
