== Publication Abstract from PubMed ==
 +
The crystal structure of pentalenene synthase at 2.6 angstrom resolution reveals critical active site features responsible for the cyclization of farnesyl diphosphate into the tricyclic hydrocarbon pentalenene. Metal-triggered substrate ionization initiates catalysis, and the alpha-barrel active site serves as a template to channel and stabilize the conformations of reactive carbocation intermediates through a complex cyclization cascade. The core active site structure of the enzyme may be preserved among the greater family of terpenoid synthases, possibly implying divergence from a common ancestral synthase to satisfy biological requirements for increasingly diverse natural products.
