General annotation (Comments)

Function

Catalyzes the cyclization of (S)-2,3 oxidosqualene to lanosterol, a reaction that forms the sterol nucleus.

Catalytic activity

(3S)-2,3-epoxy-2,3-dihydrosqualene = lanosterol.

Pathway

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

Sequence similarities

Belongs to the terpene cyclase/mutase family.

Contains 4 PFTB repeats.
