Cyclization of FPP: Two new fungal sesquiterpene synthase are described that have opposite catalytic fidelities in the cyclization of farnesyl diphosphate. Catalytic promiscuity can be drastically reduced by changing the conditions of the reaction. Conversion of the FPP geometricisomers was found to proceed via opposite enantiomers of a cyclic carbocation intermediate that are rearranged to different
