Competitive inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A reductase (the statins) that inhibit the synthesis of mevalonic acid are in wide use for treatment of hypercholesterolemia. Although antitumor effects on a variety of cell types have been reported for statins, the effect

Isoprenoids, most of them synthesized by prenyltransferases (PTSs), are a class of important biologically active compounds with diverse functions. The mint geranyl pyrophosphate synthase (GPPS) is a heterotetramer composed of two LSU·SSU (large/small subunit) dimers. In addition to C(10)-GPP, the

A mix-and-read FlashPlate (PerkinElmer, Waltham, MA) assay for the enzyme farnesyl pyrophosphate (FPP) synthase (FPPS) was developed to rapidly measure both steps in the synthesis of FPP from dimethylallyl pyrophosphate (DMAPP). The assay used either DMAPP or geranyl pyrophosphate (GPP)
Terpenes (isoprenoids), derived from isoprenyl pyrophosphates, are versatile natural compounds that act as metabolism mediators, plant volatiles, and ecological communicators. Divergent evolution of homomeric prenyltransferases (PTSs) has allowed PTSs to optimize their active-site pockets to achieve catalytic fidelity and diversity.
Farnesylation of the gamma-subunit of the retinal G-protein, transducin (Talpha/Tbetagamma), is indispensable for light-initiated signaling in photoreceptor cells. However, the farnesyl-mediated molecular interactions important for signaling are not well understood. To explore this issue, we created a functional Tbetagamma analogue
