Fungal bifunctional terpene synthases (BFTSs) reportedly associate with a series of new skeletons of di/sesterterpenes. However, the molecular mechanisms underlying the variabilities in the ring system of BFTS-catalyzed products are not well understood. In this study, we identified a key site, S89/L89, that controls the conversion between bicyclic and polycyclic terpene skeletons catalyzed by two BFTSs, BsPS and FoFS. Our analysis revealed that a mutation on site 89 in the BFTSs alters the carbocation transportation pathway and redirects the competing reactions for previously unreported terpenes.
