Enzyme Information
| 1.10.3.1 |
Catechol oxidase.
based on mapping to UniProt P43311
2 catechol + O(2) = 2 1,2-benzoquinone + 2 H(2)O.
-!- 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.
