This paper describes the structures of the asparagine-linked oligosaccharides of two forms of guinea-pig Factor B of the alternative complement pathway with different Mr values. Oligosaccharides were quantitatively liberated from both glycoproteins by hydrazinolysis, fractionated by paper electrophoresis and Bio-Gel P-4 column chromatography, and their structures determined by sequential exoglycosidase digestions in conjunction with methylation analysis. Both glycoproteins were shown to have the same biantennary complex-type oligosaccharides but it is suggested that they contain different numbers of oligosaccharide chains.
本文描述了替代补体途径中两种不同分子量的豚鼠B因子的天冬酰胺连接寡糖的结构。通过肼解从两种糖蛋白中定量释放寡糖,经纸电泳和生物凝胶P-4柱色谱法分级分离,并结合甲基化分析通过顺序外切糖苷酶消化确定其结构。结果表明,两种糖蛋白具有相同的双触角复合型寡糖,但推测它们含有的寡糖链数量不同。
