As isoprenoid biosynthetic pathway has gained importance since last few years, key enzymes of this pathway have been characterized and their functional roles in the cell metabolism have been explored using molecular biology approaches. A key enzyme in this pathway is farnesyl pyrophosphate (EC 2.5.1.10) synthase (FPPS) which supplies precursors for the biosynthesis of essential isoprenoids like carotenoids, withanolides, ubiquinones, dolichols, sterols, among others and also helps in farnesylation and geranylation of proteins. It is a chain elongation enzyme which catalyzes head to tail condensation of two molecules of isopentenyl diphosphate with dimethylallyl diphosphate to form farnesyl pyrophosphate (FPP). Recent studies have validated FPPS as a molecular target of bisphosphonates for drug development against tumors as well as human pathogens. The present paper synthesizes the information on characterization, structural and functional relationships, evolution, localization as well as advances on FPPS enzyme as a target for drug development.
