- 15-cis-4,4'-diapophytoene + 4 FAD all-trans-4,4'-diapolycopene + 4 FADH2 (overall reaction)
- (1a) 15-cis-4,4'-diapophytoene + FAD all-trans-4,4'-diapophytofluene + FADH2
- (1b) all-trans-4,4'-diapophytofluene + FAD all-trans-4,4'-diapo-zeta-carotene + FADH2
- (1c) all-trans-4,4'-diapo-zeta-carotene + FAD all-trans-4,4'-diaponeurosporene + FADH2
