Function[GGPPS_YEAST] Catalyzes the trans-addition of the 3 molecules of IPP onto DMAPP to form geranylgeranyl pyrophosphate. Required for the membrane attachment of YPT1 and SEC4. May be involved in vesicle trafficking and protein sorting.[1] [2] Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMedConsiderable effort has focused on the development of selective protein farnesyl transferase (FTase) and protein geranylgeranyl transferase (GGTase) inhibitors as cancer chemotherapeutics. Here, we report a new strategy for anticancer therapeutic agents involving inhibition of farnesyl diphosphate synthase (FPPS) and geranylgeranyl diphosphate synthase (GGPPS), the two enzymes upstream of FTase and GGTase, by lipophilic bisphosphonates. Due to dual site targeting and decreased polarity, the compounds have activities far greater than do current bisphosphonate drugs in inhibiting tumor cell growth and invasiveness, both in vitro and in vivo. We explore how these compounds inhibit cell growth and how cell activity can be predicted based on enzyme inhibition data, and using X-ray diffraction, solid state NMR, and isothermal titration calorimetry, we show how these compounds bind to FPPS and/or GGPPS.
