IUBMB Comments
Requires a molybdenum cofactor for activity. NADP+ cannot replace NAD+ and short-chain alcohols such as ethanol, isopropanol, butanol and cyclohexanol cannot replace xanthoxin as substrate . Involved in the abscisic-acid biosynthesis pathway in plants, along with EC (abscisic-aldehyde oxidase), EC (9-cis-epoxycarotenoid dioxygenase) and EC [(+)-abscisic acid 8'-hydroxylase]. Abscisic acid is a sesquiterpenoid plant hormone that is involved in the control of a wide range of essential physiological processes, including seed development, germination and responses to stress .
