all-trans-nonaprenyl-diphosphate synthase (geranylgeranyl-diphosphate specific) activity
all-trans-nonaprenyl-diphosphate synthase (geranylgeranyl-diphosphate specific) activity
Catalysis of the reaction: 5 isopentenyl diphosphate + (2E,6E,10E)-geranylgeranyl diphosphate = all-trans-nonaprenyl diphosphate + 5 diphosphate.
