| Reaction catalysed |

| Cofactor(s) |
|---|
| FAD.
|
| Comment(s) |
|---|
- Converts zeatin and related cytokinins.
- Catalyzes the oxidation of cytokinins, a family of N(6)-substituted
adenine derivatives that are plant hormones, where the substituent is
a dimethylallyl or other prenyl group.
- Although this activity was previously thought to be catalyzed by a
hydrogen-peroxide-forming oxidase, this enzyme does not require
oxygen for activity and does not form hydrogen peroxide.
- 2,6-dichloroindophenol, methylene blue, nitroblue tetrazolium,
phenazine methosulfate and Cu(2+) in the presence of imidazole can
act as acceptors.
