Phytoene desaturase (neurosporene-forming)

Template:Infobox enzyme Phytoene desaturase (neurosporene-forming) (Template:EC number, 3-step phytoene desaturase, three-step phytoene desaturase, phytoene desaturase (ambiguous), CrtI (ambiguous)) is an enzyme with systematic name 15-cis-phytoene:acceptor oxidoreductase (neurosporene-forming). This enzyme catalyses the following chemical reaction

15-cis-phytoene + 3 acceptor $\rightleftharpoons$ all-trans-neurosporene + 3 reduced acceptor (overall reaction)

(1a) 15-cis-phytoene + acceptor $\rightleftharpoons$ all-trans-phytofluene + reduced acceptor

(1b) all-trans-phytofluene + acceptor $\rightleftharpoons$ all-trans-zeta-carotene + reduced acceptor

(1c) all-trans-zeta-carotene + acceptor $\rightleftharpoons$ all-trans-neurosporene + reduced acceptor

This enzyme is involved in carotenoid biosynthesis.
