Cytokinin dehydrogenase.
based on mapping to UniProt Q9T0N8
N(6)-dimethylallyladenine + acceptor + H(2)O = adenine + 3-methylbut-2- enal + reduced acceptor.
-!- 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.
