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 + O(2) <=> 2 1,2-benzoquinone + 2 H(2)O |
| Cofactor(s) |
|---|
| Copper.
|
| 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.
