Geranylfarnesyl diphosphate synthase (EC, FGPP synthase, (all-E) geranylfarnesyl diphosphate synthase, GFPS, Fgs) is an enzyme with systematic name geranylgeranyl-diphosphate:isopentenyl-diphosphate transtransferase (adding 1 isopentenyl unit).[1][2][3][4] This enzyme catalyses the following chemical reaction

geranylgeranyl diphosphate + isopentenyl diphosphate (2E,6E,10E,14E)-geranylfarnesyl diphosphate + diphosphate

The enzyme from Methanosarcina mazei is involved in biosynthesis of the polyprenyl side-chain of methanophenazine.
