Zeatin reductase

In enzymology, zeatin reductase is an enzyme that catalyzes the chemical reaction
The three substrates of this enzyme are trans-zeatin, reduced nicotinamide adenine dinucleotide phosphate and a proton. Its products are dihydrozeatin and NADP⁺. The enzyme does not act on cis-zeatin.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is dihydrozeatin:NADP+ oxidoreductase.
