UniProt Comments
Function: Catalyzes cis-prenyl chain elongation to produce the polyprenyl backbone of dolichol, a glycosyl carrier-lipid required for the biosynthesis of several classes of glycoprotein.Catalytic activity: (2E,6E)-farnesyl diphosphate + n isopentenyl diphosphate = n diphosphate + ditrans,polycis-polyprenyl diphosphate (n = 10-55).Cofactor: Magnesium.Pathway: Protein modification; protein glycosylation.Subcellular location: Endoplasmic reticulum membrane; Single-pass membrane protein. Tissue specificity: Expressed in low levels in the whole plant. Preferentially expressed in roots.Sequence similarities: Belongs to the UPP synthase family.Biophysicochemical propertiesKinetic parameters:KM=0.13 µM for farnesyl diphosphate (FPP)KM=3.62 µM for geranylgeranyl diphosphate (GGPP)KM=23 µM for isopentenyl diphosphate (IPP)
