DE   carotenoid 9,10-dioxygenase.
AN   carotenoid 9,10(9',10')-cleavage dioxygenase.
AN   carotenoid cleavage dioxygenase.
CA   all-trans-zeaxanthin + 2 O2 = 2 (3R)-hydroxy-beta-ionone + 4,9-
CA   dimethyldodeca-2,4,6,8,10-pentaenedial.
CC   -!- Presumably the enzyme acts twice on zeaxanthin cleaving 3-hydroxy-
CC       beta-ionone off each 3-hydroxy end group.
