9,9'-dicis-zeta-carotene desaturase (, zeta-carotene desaturase, ZDS) is an enzyme with systematic name 9,9'-dicis-zeta-corotene:quinone oxidoreductase. This enzyme catalyses the following chemical reaction
9,9'-dicis-zeta-carotene + 2 quinone 7,9,7',9'-tetracis-lycopene + 2 quinol (overall reaction) (1a) 9,9'-dicis-zeta-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
This enzyme is involved in carotenoid biosynthesis in plants and cyanobacteria.
