UniProt Comments
Involved in the solanesyl diphosphate biosynthesis in the endoplasmic reticulum. This isoprenoid side chain might be then transferred to the mitochondria for the synthesis of ubiquinone-9. Prefers geranylgeranyl diphosphate to farnesyl diphosphate as substrate. No activity with geranyl diphosphate or dimethylallyl diphosphate as substrate.
