Farnesyl pyrophosphate synthase (FDPS)

Key enzyme in isoprenoid biosynthesis that 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 consequent geranylpyrophosphate to the best product farnesyl pyrophosphate. .
