Protein

Squalene synthase

Gene

ERG9

Organism
Ustilago maydis (strain 521 / FGSC 9021) (Corn smut fungus)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Catalyzes the condensation of 2 two farnesyl pyrophosphate moieties to form squalene. It is the first committed enzyme of the sterol biosynthesis pathway. Required for the biosynthesis of ergosterol (By similarity).By similarity

Catalytic activityi

2 farnesyl diphosphate + NAD(P)H = squalene + 2 diphosphate + NAD(P)+.

Cofactori

Magnesium.By similarity
