- FUNCTION: Has a 11,12(11',12') 9-cis epoxycarotenoid cleavage activity. Catalyzes the first step of abscisic-acid biosynthesis from carotenoids, in response to water stress.
- CATALYTIC ACTIVITY: A 9-cis-epoxycarotenoid + O2 = 2-cis,4-trans-xanthoxin + a 12'-apo-carotenal.
- CATALYTIC ACTIVITY: 9-cis-violaxanthin + O2 = 2-cis,4-trans-xanthoxin + (3S,5R,6S)-5,6-epoxy-3-hydroxy-5,6-dihydro-12'-apo-beta-caroten-12'-al.
- CATALYTIC ACTIVITY: 9'-cis-neoxanthin + O2 = 2-cis,4-trans-xanthoxin + (3S,5R,6R)-5,6-dihydroxy-6,7-didehydro-5,6-dihydro-12'-apo-beta-caroten-12'-al.
- ENZYME REGULATION: Inhibited by abamine and abamineSG.
- SUBCELLULAR LOCATION: Plastid, chloroplast stroma. Note=Partially bound to the thylakoid.
- TISSUE SPECIFICITY: Localized in roots, leaves, stems, empty silique envelopes and seeds. Expressed at the point of organ attachment and the abscission zones in the plant.
- INDUCTION: By salt or drought stress and pathogen.
- MISCELLANEOUS: Loss-of-function mutants (T-DNA insertion) show enhanced germination on salt and hypersensitivity to desication and LiCl. Overexpresion of NCED3 results in increased accumulation of abscisic acid and resistance to water stress.
- SIMILARITY: Belongs to the carotenoid oxygenase family.
