The lipid moiety of a lipid diphosphate N-acetylglucosamine, an intermediate in glycosylation of proteins, was studied. Ozonolysis of the compound gave evidence for an alpha-saturated isoprene unit. Alkaline hydrolysis of the glycolipid, followed by high-pressure liquid chromatography, showed the presence of a series of polyprenol homologues identical with those isolated directly from Saccharomyces cerevisiae (baker's yeast). No particular homologue was preferred in the enzymic transfer of N-acetylglucosamine 1-phosphate to endogenous dolichol monophosphate.
对蛋白质糖基化过程中的中间体——脂二磷酸N-乙酰葡糖胺的脂质部分进行了研究。该化合物的臭氧化反应证明存在一个α-饱和异戊二烯单元。糖脂经碱性水解后,通过高压液相色谱分析,结果表明存在一系列与直接从酿酒酵母(面包酵母)中分离出的聚戊烯醇同系物相同的物质。在N-乙酰葡糖胺1-磷酸向内源性磷酸多萜醇的酶促转移过程中,未发现对特定同系物有偏好。
