Abstract
Chemoenzymatic synthesis of non-natural terpenes using the promiscuous activity of terpene synthases allows for the expansion of the chemical space of terpenoids with potentially new bioactivities. In this report, we describe protocols for the preparation of a novel aphid attractant, (S)-14,15-dimethylgermacrene D, by exploiting the promiscuity of (S)-germacrene D synthase from Solidago canadensis and using an engineered biocatalytic route to convert prenols to terpenoids. The method uses a combination of five enzymes to carry out the preparation of terpenoid semiochemicals in two steps: (1) diphosphorylation of five or six carbon precursors (prenol, isoprenol and methyl-isoprenol) catalyzed by Plasmodium falciparum choline kinase and Methanocaldococcus jannaschii isopentenyl phosphate kinase to form DMADP, IDP and methyl-IDP, and (2) chain elongation and cyclization catalyzed by Geobacillus stearothermophilus (2E,6E)-farnesyl diphosphate synthase and S. canadensis (S)-germacrene D synthase to produce (S)-germacrene D and (S)-14,15-dimethylgermacrene D. Using this method, new non-natural terpenoids are readily accessible and the approach can be adopted to produce different terpene analogs and terpenoid derivatives with potential novel applications.
