catechol oxidase

catechol oxidase
cat·e·chol ox·i·dase (katґə-kol okґsĭ-dās) [EC 1.10.3.1] any of a group of enzymes of the oxidoreductase class that catalyze the oxidation of catechols to 1,2-benzoquinones. They are copper-containing proteins that act also upon substituted catechols and many catalyze the reaction of monophenol monooxygenase. The group includes enzymes called also diphenol oxidase or polyphenol oxidase, based on their substrates. Cf. monophenol monooxygenase.
