all-trans-nonaprenyl diphosphate synthase [geranylgeranyl-diphosphate specific]

Geranylgeranyl diphosphate is preferred over farnesyl diphosphate as allylic substrate. The plant Arabidopsis thaliana has two different enzymes that catalyse this reaction. SPS1 contributes to the biosynthesis of the ubiquinone side-chain while SPS2 supplies the precursor of the plastoquinone side-chains.
