geranylgeranyl-diphosphate:isopentenyl-diphosphate transtransferase (adding 5 isopentenyl units)
Geranylgeranyl diphosphate is preferred over farnesyl diphosphate as allylic substrate [1]. 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 [2].
