ENZYME entry: EC 1.10.3.1

Accepted Name
catechol oxidase
Alternative Name(s)
diphenol oxidase
o-diphenolase
phenolase
polyphenol oxidase
tyrosinase
Reaction catalysed
2 catechol + O2 = 2 1,2-benzoquinone + 2 H2O
Comment(s)
  • A type 3 copper protein that catalyzes exclusively the oxidation of catechols (i.e., o-diphenols) to the corresponding o-quinones.
  • The enzyme also acts on a variety of substituted catechols.
  • It is different from tyrosinase, EC 1.14.18.1, which can catalyze both the monooxygenation of monophenols and the oxidation of catechols.
