Xanthoxin dehydrogenase

In enzymology, a xanthoxin dehydrogenase (Template:EC number) is an enzyme that catalyzes the chemical reaction

xanthoxin + NAD⁺ $\rightleftharpoons$ abscisic aldehyde + NADH + H⁺

Thus, the two substrates of this enzyme are xanthoxin and NAD⁺, whereas its 3 products are abscisic aldehyde, NADH, and H⁺.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD⁺ or NADP⁺ as acceptor. The systematic name of this enzyme class is xanthoxin:NAD⁺ oxidoreductase. Other names in common use include xanthoxin oxidase, and ABA2. This enzyme participates in carotenoid biosynthesis.
