General annotation (Comments)

Function	Has a 11,12(11',12') 9-cis epoxycarotenoid cleavage activity. Catalyzes the first step of abscisic-acid biosynthesis from carotenoids By similarity.
Catalytic activity	A 9-cis-epoxycarotenoid + O2 = 2-cis,4-trans-xanthoxin + a 12'-apo-carotenal. 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. 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.
Subunit structure	Interacts in vitro with VAR3. Ref.5
Subcellular location	Plastid › chloroplast thylakoid membrane. Ref.5 Ref.4
Tissue specificity	Detected only in seeds. Ref.4 Ref.6
Developmental stage	Expressed at later stages of seed maturation. Ref.6
Induction	Low induction by drought stress. Ref.4 Ref.3
Sequence similarities	Belongs to the carotenoid oxygenase family.
