DE   Beta-carotene 15,15'-monooxygenase.
AN   Beta-carotene 15,15'-dioxygenase.
AN   Carotene 15,15'-dioxygenase.
AN   Carotene dioxygenase.
CA   Beta-carotene + O(2) = 2 retinal.
CF   Bile salt; Iron.
CC   -!- The reaction proceeds in three stages, epoxidation of the
CC       15,15'-double bond, hydration of the double bond leading to ring
CC       opening, and oxidative cleavage of the diol formed (cf.
CC       EC 1.14.15.6).
CC   -!- Thus only one atom of the dioxygen is incorporated into retinal.
CC   -!- Formerly EC 1.13.11.21 and EC 1.18.3.1.
