All-trans-nonaprenyl-diphosphate synthase (geranyl-diphosphate specific) (EC 2.5.1.84, nonaprenyl diphosphate synthase, solanesyl diphosphate synthase, SolPP synthase, SPP-synthase, SPP synthase, solanesyl-diphosphate synthase, OsSPS2) is an enzyme with systematic name geranyl-diphosphate:isopentenyl-diphosphate transtransferase (adding 7 isopentenyl units).[1][2][3][4][5][6] This enzyme catalyses the following chemical reaction

geranyl diphosphate + 7 isopentenyl diphosphate 7 diphosphate + all-trans-nonaprenyl diphosphate

This enzyme is involved in the synthesis of the side chain of menaquinone-9.
