All-trans-nonaprenyl-diphosphate synthase (geranyl-diphosphate specific)

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 ${\displaystyle \rightleftharpoons }$ 7 diphosphate + all-trans-nonaprenyl diphosphate
