FDPS Protein, a key enzyme in isoprenoid biosynthesis, catalyzes the formation of farnesyl diphosphate (FPP). FPP is a precursor for essential metabolites like sterols, dolichols, carotenoids, and ubiquinones. It also serves as a substrate for protein farnesylation and geranylgeranylation. FDPS sequentially condenses isopentenyl pyrophosphate with dimethylallyl pyrophosphate and then with geranylpyrophosphate to produce farnesyl pyrophosphate. FDPS Protein, Human (His) is the recombinant human-derived FDPS protein, expressed by E. coli , with N-His labeled tag.
