ID   2.5.1.85
DE   all-trans-nonaprenyl-diphosphate synthase [geranylgeranyl-diphosphate
DE   specific].
AN   nonaprenyl diphosphate synthase.
AN   solanesyl diphosphate synthase.
CA   (2E,6E,10E)-geranylgeranyl diphosphate + 5 isopentenyl diphosphate = all-
CA   trans-nonaprenyl diphosphate + 5 diphosphate.
CC   -!- Geranylgeranyl diphosphate is preferred over farnesyl diphosphate as
CC       allylic substrate.
CC   -!- The plant Arabidopsis thaliana has two different enzymes that
CC       catalyze this reaction.
CC   -!- SPS1 contributes to the biosynthesis of the ubiquinone side-chain
CC       while SPS2 supplies the precursor of the plastoquinone side-chains.
CC   -!- Formerly EC 2.5.1.11.
