Our spotlight on the work of Tao and colleagues that discovered a new pathway for triterpene biosynthesis in which bifunctional class I terpene synthases from fungi catalyze both the synthesis of HexPP and its cyclization via their prenyltransferase (PTd) and terpene cyclase (TCd) domains.

Triterpenes are C30 organic compounds abundantly found in all living organisms. Although previously believed to be exclusively produced from squalene or oxidosqualene, a recent report by Tao and colleagues describes a new triterpene biosynthetic route involving the cyclization of the precursor hexaprenyl diphosphate (HexPP) by unprecedented bifunctional terpene synthase (TS) enzymes.
