Protein

Beta,beta-carotene 15,15'-monooxygenase

Gene

BCO1

Organism
Gallus gallus (Chicken)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Symmetrically cleaves beta-carotene into two molecules of retinal. 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.

Catalytic activityi

Beta-carotene + O2 = 2 all-trans-retinal.

Cofactori

Fe2+Note: Binds 1 Fe2+ ion per subunit.
