Function 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. {ECO:0000269|PubMed:20884803, ECO:0000269|PubMed:9188535, ECO:0000269|PubMed:9342392}.
