- FUNCTION: Has a 11,12(11',12') 9-cis epoxycarotenoid cleavage activity. Catalyzes the first step of abscisic-acid biosynthesis from carotenoids. Contributes probably to abscisic acid synthesis for the induction of seed dormancy.
- 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.
- SUBCELLULAR LOCATION: Plastid, chloroplast stroma.
- TISSUE SPECIFICITY: Expressed in developing siliques, embryo and endosperm.
- DEVELOPMENTAL STAGE: Expressed in seeds at early and mid-maturation stages.
- INDUCTION: Low induction by drought stress.
- MISCELLANEOUS: Loss-of-function mutants (T-DNA insertion) exhibit abscisic-acid-deficient phenotypes in seeds, but not in vegetative tissues.
- SIMILARITY: Belongs to the carotenoid oxygenase family.
