UniProtKB - Q9LRM7 (NCED6_ARATH)
Protein
9-cis-epoxycarotenoid dioxygenase NCED6, chloroplastic
Gene
NCED6
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Functioni
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.2 Publications
