All-trans-8'-apo-beta-carotenal 15,15'-oxygenase (EC 1.14.99.41, Diox1, ACO, 8'-apo-beta-carotenal 15,15'-oxygenase) is an enzyme with systematic name all-trans-8'-apo-beta-carotenal:oxygen 15,15'-oxidoreductase (bond-cleaving).[1][2] This enzyme catalyses the following chemical reaction

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 15,15'-oxygenase contains an Fe2+-4His arrangement.
