General annotation (Comments)

Function

Critical branch point enzyme of isoprenoid biosynthesis that is thought to regulate the flux of isoprene intermediates through the sterol pathway By similarity.

Catalytic activity

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

Cofactor

Magnesium By similarity.

Pathway

Terpene metabolism; lanosterol biosynthesis; lanosterol from farnesyl diphosphate: step 1/3.

Subcellular location

Endoplasmic reticulum membrane; Multi-pass membrane protein By similarity.

Sequence similarities

Belongs to the phytoene/squalene synthase family.
