The capacity of isolated membrane fractions to catalyse transfer of sugars from sugar nucleotides to alpha-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.
研究了分离的膜组分催化糖从糖核苷酸转移至磷酸化C85和C55多萜醇以及视黄基磷酸的α-饱和与不饱和形式的能力。还测定了各种糖存在时内源性脂质受体的量。粗糙微粒体组分、光滑微粒体组分和高尔基体膜中存在的多萜醇磷酸的类型和量似乎有所不同,且各个多萜醇磷酸作为糖受体表现出特异性。
