Thus, the two substrates of this enzyme are dihydrozeatin and NADP⁺, whereas its 3 products are zeatin, NADPH, and H⁺.

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.
