tetraprenyl‐β‐curcumene synthase homologue from the alkalophilic Bacillus clausii catalyses conversions of a geranylfarnesyl diphosphate and a hexaprenyl diphosphate into novel head‐to‐tail acyclic sesterterpene and triterpene. Tetraprenyl‐β‐curcumene synthase homologues represent a new family of terpene synthases that form not only sesquarterpene but also sesterterpene and triterpene.

Multifunctional terpene biosynthetic enzymes: Geranylfarnesyl diphosphate (GFPP), hexaprenyl diphosphate (HexPP), and heptaprenyl diphosphate (HepPP) are intermediates in two isoprenoid pathways and are biosynthesized by one trifunctional (all‐E)‐isoprenyl diphosphate synthase. GFPP/HexPP and HepPP are mainly utilized for the biosynthesis of acyclic terpenes and menaquinone‐7, respectively.
