method of forming C-O bonds and cyclic ethers in synthetic chemistry. In studying the biosynthesis of the fungal natural product herqueinone, we identified an enzyme that can perform an intramolecularenantioselective hydroalkoxylation reaction. PhnH catalyzes the addition of a phenol to the terminal olefin of a reverse prenyl group to give a dihydrobenzofuran product. The enzyme accelerates the reaction

study highlights the biochemical and structural characterization of the L-tryptophan C6 C-prenyltransferase (C-PT) PriB fromStreptomyces sp. RM-5-8. PriB was found to be uniquely permissive to a diverse array of prenyl donors and acceptors including daptomycin. Two additional PTs also produced novel prenylated daptomycins with improved antibacterial activities over the parent drug.

The mevalonate pathway is an important drug target for the treatment of cancer and cardiovascular disease. We synthesized and studied a new type of nitrogen-containing bisphosphonate analogs and developed a sensitive end point assay method for enzyme FPPS, which was used for inhibitor screening. One potent FPPS inhibitor was discovered, and the structure-activity relationship of bisphosphonates for

Better conversion of l-o- and l-m-tyrosine to their C-prenylated derivatives by tryptophan prenyltransferases (Trp-PTs) than tyrosine O-prenyltransferases (Tyr-O-PT).

Twobacterialditerpenesynthases (DTSs) from Chryseobacterium were characterised. The first enzyme yielded the new compound chryseodiene that closely resembles the known fusicoccane diterpenes from fungi, but its experimentally and computationally studied cyclisation mechanism is fundamentally different to the mechanism of fusicoccadiene synthase. The second enzyme produced wanjudiene, a diterpene
