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.
