ENZYME entry: EC 2.5.1.85

Accepted Name
All-trans-nonaprenyl-diphosphate synthase (geranylgeranyl-diphosphate specific).
Alternative Name(s)
Nonaprenyl diphosphate synthase.
Solanesyl diphosphate synthase.
Reaction catalysed
Geranylgeranyl diphosphate + 5 isopentenyl diphosphate <=> 5 diphosphate + all-trans-nonaprenyl diphosphate
Comment(s)
  • Geranylgeranyl diphosphate is preferred over farnesyl diphosphate as allylic substrate.
  • The plant Arabidopsis thaliana has two different enzymes that catalyze this reaction.
  • SPS1 contributes to the biosynthesis of the ubiquinone side-chain while SPS2 supplies the precursor of the plastoquinone side-chains.
  • Formerly EC 2.5.1.11.
