General annotation (Comments)

Function

Protostadienol synthase which cyclizes (3S)-oxidosqualene to (17Z)-protosta-17(20),24-dien-3-beta-ol (protostadienol), the biosynthetic precursor of helvolic acid, a secundary metabolite which promotes virulence. Ref.2

Catalytic activity

(3S)-2,3-epoxy-2,3-dihydrosqualene = (17Z)-protosta-17(20),24-dien-3-beta-ol. Ref.2

Sequence similarities

Belongs to the terpene cyclase/mutase family.

Contains 4 PFTB repeats.
