comment
  • 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 Expressed in vascular bundles of roots and leaves, vascular parenchyma cells of leaves, anther filaments, xylem tissue of anthers, embryos, radicles and coleoptiles.INDUCTION Induced by abscisic acid (ABA) and salt (PubMed:18326788, PubMed:25283804). Induced by drought stress (PubMed:20838584, PubMed:25283804, PubMed:25418692, PubMed:25735958). Induced by D-allose (PubMed:23397192). Induced by infection with the bacterial pathogen Xanthomonas oryzae pv. oryzae (Xoo) (PubMed:23826294, PubMed:26718470). Down-regulated by submergence (PubMed:17205969).SIMILARITY Belongs to the carotenoid oxygenase family.
