| 1.3.5.5 | 15-cis-phytoene + 2 plastoquinone |
phytoene desaturase is an early enzyme of the carotenoid biosynthetic pathway |
| 1.3.5.5 | 15-cis-phytoene + 2 plastoquinone |
the biosynthetic pathway of carotenoid synthesis involves several steps of desaturation requiring free energy, for instance the transition from phytoene to phytofluene achieved by phytoene desaturase. This reaction is associated with a reduction of plastoquinone. The oxidation of the plastoquinol is then achieved by a plastoquinol:oxygen oxidoreductase. Might additionally mediate the reduction of plastoquinone by internal reductants |

geranylgeranyl diphosphate is catalysed by phytoene synthase and phytoene desaturase to phytoene and phytofluene, respectively. The subsequent steps involve desaturation, isomerisation and cyclisation reactions to form alpha- and beta-carotene stereoisomers, via all-trans lycopene |
