15-cis-phytoene:acceptor oxidoreductase (3,4-didehydrolycopene-forming)
This enzyme is involved in carotenoid biosynthesis and catalyses up to five desaturation steps (cf. EC 1.3.99.28 [phytoene desaturase (neurosporene-forming)], EC 1.3.99.29 [phytoene desaturase (zeta-carotene-forming)] and EC 1.3.99.31 [phytoene desaturase (lycopene-forming)]).
