  • FUNCTION Has a 11,12(11',12') 9-cis epoxycarotenoid cleavage activity. Catalyzes the first step of abscisic-acid biosynthesis from carotenoids.CATALYTIC ACTIVITY a 9-cis-epoxycarotenoid + O2 = a 12'-apo-carotenal + 2-cis,4-trans-xanthoxinCATALYTIC ACTIVITY 9-cis-violaxanthin + O2 = (3S,5R,6S)-5,6-epoxy-3-hydroxy-5,6-dihydro-12'-apo-beta-caroten-12'-al + 2-cis,4-trans-xanthoxinCATALYTIC ACTIVITY 9'-cis-neoxanthin + O2 = (3S,5R,6R)-3,5-dihydroxy-6,7-didehydro-5,6-dihydro-12'-apo-beta-caroten-12'-al + 2-cis,4-trans-xanthoxinCOFACTOR Binds 1 Fe(2+) ion per subunit.SUBCELLULAR LOCATION Induced by abscisic acid (ABA) and salt (PubMed:18326788). Induced by D-allose (PubMed:23397192). Induced by drought stress (PubMed:25418692, PubMed:25735958).SIMILARITY Belongs to the carotenoid oxygenase family.
