| EC Number | 1.10.3.1 |
| CAS Registry Number | 9002/10/2 |
| Comments | A type 3 copper protein that catalyses 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 catalyse both the monooxygenation of monophenols and the oxidation of catechols. |
| Cofactor | Cu cation |
| History | |
| Reactions | 2 catechol + O(2) = 2 1,2-benzoquinone + 2 H(2)O. |
