Phytoene desaturase (3,4-didehydrolycopene-forming) (5-step phytoene desaturase, five-step phytoene desaturase, phytoene desaturase (ambiguous), Al-1) is an enzyme with systematic name 15-cis-phytoene:acceptor oxidoreductase (3,4-didehydrolycopene-forming).[1] [2] This enzyme catalyses the following chemical reaction
15-cis-phytoene + 5 acceptor
all-
trans-3,4-didehydrolycopene + 5 reduced acceptor (overall reaction)
(1a) 15-cis-phytoene + acceptor
all-trans-phytofluene + reduced acceptor
(1b) all-trans-phytofluene + acceptor
all-trans-zeta-carotene + reduced acceptor
(1c) all-trans-zeta-carotene + acceptor
all-trans-neurosporene + reduced acceptor
(1d) all-trans-neurosporene + acceptor
all-trans-lycopene + reduced acceptor
(1e) all-trans-lycopene + acceptor
all-
trans-3,4-didehydrolycopene + reduced acceptor
This enzyme is involved in carotenoid biosynthesis.
