catechol oxidase activity [GO_0004097]

Catalysis of the reaction: 2 catechol + O2 = 2 1,2-benzoquinone + 2 H2O. This reaction catalyzes exclusively the oxidation of catechols (i.e., o-diphenols) to the corresponding o-quinones.

Class

Catalysis of the reaction: 2 catechol + O2 = 2 1,2-benzoquinone + 2 H2O. This reaction catalyzes exclusively the oxidation of catechols (i.e., o-diphenols) to the corresponding o-quinones.

GO:0004097 describes oxidation of catechols (i.e., o-diphenols) to the corresponding o-quinones. For monooxygenation of monophenols, consider instead the term 'monophenol monooxygenase activity ; GO:0004503'.
