Catechol oxidase
Definition:
EC Tree > 1 Oxidoreductases > 1.10 Acting on diphenols and related substances as donors > 1.10.3 With oxygen as acceptor > 1.10.3.1 catechol oxidase
Catechol oxidase is a type 3 copper protein that specifically oxidizes catechols (o-diphenols) to the corresponding o-quinones, acting on a variety of substituted catechols. It differs from tyrosinase (EC 1.14.18.1), which can both monooxygenate monophenols and oxidize catechols; with 2 catechol and O2 it yields 2 1,2-benzoquinone and 2 H2O.
