4,4'-Diapophytoene desaturase

Template:Short description Template:Infobox enzyme 4,4'-Diapophytoene desaturase (Template:EC number, dehydrosqualene desaturase, CrtN, 4,4'-diapophytoene:FAD oxidoreductase) is an enzyme with systematic name Template:Chem name.^[1]^[2]^[3] This enzyme catalyses the following chemical reaction

15-cis-4,4'-diapophytoene + 4 FAD

⇌

all-trans-4,4'-diapolycopene + 4 FADH2 (overall reaction)

(1a) 15-cis-4,4'-diapophytoene + FAD

⇌

all-trans-4,4'-diapophytofluene + FADH2

(1b) all-trans-4,4'-diapophytofluene + FAD

⇌

all-trans-4,4'-diapo-zeta-carotene + FADH2

(1c) all-trans-4,4'-diapo-zeta-carotene + FAD

⇌

all-trans-4,4'-diaponeurosporene + FADH2

(1d) all-trans-4,4'-diaponeurosporene + FAD

⇌

all-trans-4,4'-diapolycopene + FADH2

This enzyme is typical of Staphylococcus aureus and some other bacteria such as Heliobacillus sp.
