== Function ==

[https://www.uniprot.org/uniprot/FPPS_HUMAN FPPS_HUMAN] Key enzyme in isoprenoid biosynthesis which catalyzes the formation of farnesyl diphosphate (FPP), a precursor for several classes of essential metabolites including sterols, dolichols, carotenoids, and ubiquinones. FPP also serves as substrate for protein farnesylation and geranylgeranylation. Catalyzes the sequential condensation of isopentenyl pyrophosphate with the allylic pyrophosphates, dimethylallyl pyrophosphate, and then with the resultant geranylpyrophosphate to the ultimate product farnesyl pyrophosphate.

== Publication Abstract from PubMed ==
 +
Farnesyl pyrophosphate synthase (FPPS) catalyzes the condensation of isopentenyl pyrophosphate (IPP) and dimethylallyl pyrophosphate to FPP and is known to be a molecular target of osteoporosis drugs, such as risedronate (RIS), which is a nitrogen-containing bisphosphonate. The protonation states and hydration structure of RIS bound to FPPS were determined by neutron protein crystallography, which allows direct visualization of hydrogens and deuteriums. The structure analysis revealed that the phosphate groups of RIS were fully deprotonated with the abnormally decreased pKa, and that the roles of E93 and D264 consisted of canceling the extra negative charges upon the binding of ligands. Collectively, our neutron structures provided insights into the physicochemical properties during the bisphosphonate binding event.
