3npe
Structure of VP14 in complex with oxygenStructure of VP14 in complex with oxygen
FunctionFunction
[NCED1_MAIZE] Has a 11,12(11',12') 9-cis epoxycarotenoid cleavage activity. Catalyzes the first step of abscisic-acid biosynthesis from carotenoids. Not active on the all-trans isomers of violaxanthin and neoxanthin. Contributes probably to abscisic acid synthesis for the induction of seed dormancy.[1] [2] [3]
