ENZYME entry: EC 1.14.99.36

Accepted Name
Beta-carotene 15,15'-monooxygenase.
Alternative Name(s)
Beta-carotene 15,15'-dioxygenase.
Carotene 15,15'-dioxygenase.
Carotene dioxygenase.
Reaction catalysed
Beta-carotene + O(2) <=> 2 all-trans-retinal
Cofactor(s)
Fe(2+).
Comment(s)
  • The reaction proceeds in three stages, epoxidation of the 15,15'-double bond, hydration of the double bond leading to ring opening, and oxidative cleavage of the diol formed (cf. EC 1.14.15.6).
  • Thus only one atom of the dioxygen is incorporated into retinal.
  • Formerly EC 1.13.11.21 and EC 1.18.3.1.
