Description
Requires Fe2+. The enzyme cleaves β-carotene symmetrically, producing two molecules of all-trans-retinal. Both atoms of the oxygen molecule are incorporated into the products. The enzyme can also process β-cryptoxanthin, 8'-apo-β-carotenal, 4'-apo-β-carotenal, α-carotene and γ-carotene in decreasing order. The presence of at least one unsubstituted β-ionone ring in a substrate greater than C30 is mandatory. A prokaryotic enzyme has been reported from the uncultured marine bacterium 66A03, where it is involved in the proteorhodopsin system, which uses retinal as its chromophore.
Form
Liquid or lyophilized powder
Storage
Store it at +4 ºC for short term. For long term storage, store it at -20 ºC～-80 ºC.
Synonyms
blh (gene name); BCO1 (gene name); BCDO (gene name); carotene dioxygenase; carotene 15,15'-dioxygenase; BCMO1 (misleading); β-carotene 15,15'-monooxygenase (incorrect)
Reaction
β-carotene + O2 = 2 all-trans-retinal
