| Accepted name: |
9,9′-dicis-ζ-carotene desaturase |
| Reaction: |
9,9′-dicis-ζ-carotene + 2 quinone = 7,9,7′,9′-tetracis-lycopene + 2 quinol (overall reaction)
(1a) 9,9′-dicis-ζ-carotene + a quinone = 7,9,9′-tricis-neurosporene + a quinol
(1b) 7,9,9′-tricis-neurosporene + a quinone = 7,9,7′,9′-tetracis-lycopene + a quinol |
