Protein

Probable squalene synthase

Gene

erg-6

Organism
Neurospora crassa (strain ATCC 24698 / 74-OR23-1A / CBS 708.71 / DSM 1257 / FGSC 987)
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
