Xanthoxin dehydrogenase

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.
