Structure of VP14 in complex with oxygen
Template:ABSTRACT PUBMED 20884803
Function
[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]
About this Structure
3npe is a 1 chain structure with sequence from Zea mays. Full crystallographic information is available from OCA.
