Type I terpene synthases generate complex polycyclic scaffolds through carbocation cascades. However, how closely related enzymes convert a common C25 precursor to distinct sesterterpene frameworks remains unresolved. Here, we combine high-resolution crystal structures with systematic mutagenesis of four bacterial sest...

Terpene cyclases (TCs) typically transform acyclic oligoprenyl pyrophosphates through carbocationic cyclization cascades. However, recently discovered bacterial pathways generate compact, cyclized and stereochemically defined noncanonical intermediates through methyltransferases prior to TC catalysis, raising the que...

This study lays the foundation for future research on terpene biosynthesis in Collembola, an ancient lineage of arthropods by revealing several unusual mechanistic aspects such as the formation of a series of enantiomerically pure products besides one scalemic compound.
