The N-linked oligosaccharides from baker's yeast carboxypeptidase Y were analyzed by 1H NMR and specific mannosidase digestion and found to be identical to those from the Saccharomyces cerevisiae mnn9 mutant bulk mannoprotein. The results support the view that the mnn mutants make oligosaccharides that are a true reflection of the normal biosynthetic pathway and confirm that a recently revised yeast oligosaccharide structure is applicable to wild-type mannoproteins.
通过1H核磁共振和特定甘露糖苷酶消化对来自面包酵母羧肽酶Y的N-连接寡糖进行了分析,发现其与来自酿酒酵母mnn9突变体大量甘露糖蛋白的寡糖相同。这些结果支持了这样一种观点,即mnn突变体产生的寡糖是正常生物合成途径的真实反映,并证实了最近修订的酵母寡糖结构适用于野生型甘露糖蛋白。
