all-trans-8'-apo-beta-carotenal + O2 = all-trans-retinal + (2E,4E,6E)-2,6-dimethylocta-2,4,6-trienedial
all-trans-8'-apo-beta-carotenal + O2 = all-trans-retinal + (2E,4E,6E)-2,6-dimethylocta-2,4,6-trienedial
on binding, three consecutive double bonds of the carotenoid change from a straight all-trans to a cranked cis-trans-cis conformation. The remaining trans bond is located at the dioxygen-ligated Fe2+ and cleaved by oxygen
all-trans-8'-apo-beta-carotenal + O2 = all-trans-retinal + (2E,4E,6E)-2,6-dimethylocta-2,4,6-trienedial
the enzyme utilizes a non-heme iron center to oxidatively cleave a carbon-carbon double bond of a carotenoid substrate
