Glycosyl transfer from nucleotide sugars to C₈₅-and C₅₅-polyprenyl and retinyl phosphates by microsomal subfractions and Golgi membranes of rat liver

The capacity of isolated membrane fractions to catalyse transfer of sugars from sugar nucleotides to α-saturated and non-saturated forms of phosphorylated C₈₅ and C₅₅ polyprenols and retinyl phosphate was examined. The amount of endogenous lipid acceptor present for various sugars was also measured. It appears that the types and amounts of polyprenyl phosphates present in rough- and smooth-microsomal fractions and Golgi membranes are different and the individual polyprenyl phosphates exhibit specificity as sugar acceptors.
