Likewise, Geranylgeranyl diphosphate synthase (GGPPS) uses FPP as a substrate and adds another IPP to form Geranylgeranyl diphosphate (GGPP) with 20 carbons.
They are made by the cyclization of geranylgeranyl diphosphate (GGPP) to form the intermediate elisabethatriene, which is in turn converted to a variety of final products (Figure 6).
