Enzyme Information
| 2.5.1.85 |
All-trans-nonaprenyl-diphosphate synthase (geranylgeranyl-diphosphate specific).
based on mapping to UniProt Q5HZ00
Geranylgeranyl diphosphate + 5 isopentenyl diphosphate = 5 diphosphate + all-trans-nonaprenyl diphosphate.
-!- 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.
