General annotation (Comments)

Function

Catalyzes the first oxygenation step in sterol biosynthesis and is suggested to be one of the rate-limiting enzymes in this pathway.

Catalytic activity

Squalene + NADPH + O2 = (3S)-2,3-epoxy-2,3-dihydrosqualene + NADP+ + H2O.

Cofactor

FAD.

Pathway

Terpene metabolism; lanosterol biosynthesis; lanosterol from farnesyl diphosphate: step 2/3.

Subunit structure

May form a complex with squalene synthase.

Subcellular location

Microsome membrane; Multi-pass membrane protein. Endoplasmic reticulum membrane; Multi-pass membrane protein.

Sequence similarities

Belongs to the squalene monooxygenase family.
