In enzymology, xanthoxin dehydrogenase (EC 1.1.1.288) is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme are xanthoxin and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are abscisic aldehyde, reduced NADH, and a proton.[1][2][3][4]
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.
