ID 1.1.1.288 DE xanthoxin dehydrogenase. AN xanthoxin oxidase. CA 2-cis,4-trans-xanthoxin + NAD(+) = 2-cis-(+)-abscisic aldehyde + H(+) + CA NADH. CC -!- NADP(+) cannot replace NAD(+) and short-chain alcohols such as CC ethanol, isopropanol, butanol and cyclohexanol cannot replace CC xanthoxin as substrate. CC -!- Involved in the abscisic-acid biosynthesis pathway in plants, along CC with EC 1.2.3.14, EC 1.13.11.51 and EC 1.14.13.93. DR Q9C826, ABA2_ARATH ; //
