Abstract

The tetrasaccharide beta-D-glucopyranosyl-(1,3)-beta-D-glucopyranuronyl-(1, 2)-L-glycero-alpha-D-manno-heptopyranosyl-(1,5)-3-deoxy-D-manno-2- octulosonic acid was isolated after treatment of polysaccharide 1 of Bordetella pertussis endotoxin with nitrous acid. Taking into account previously identified di- and trisaccharide fragments and analytical data obtained for the intact polysaccharide 1, we present the structure of a heptasaccharide that is thought to represent the region immediately adjacent to the hydrophobic (lipid A) moiety of lipopolysaccharide 1 of the B. pertussis endotoxin. This heptasaccharide represents 50 to 60% of the complete polysaccharide structure.

摘要

用亚硝酸处理百日咳博德特氏菌内毒素的多糖1后,分离出四糖β-D-吡喃葡萄糖基-(1,3)-β-D-吡喃葡萄糖醛酸基-(1, 2)-L-甘油-α-D-甘露庚糖基-(1,5)-3-脱氧-D-甘露-2-辛酮糖酸。考虑到先前鉴定的二糖和三糖片段以及完整多糖1获得的分析数据,我们提出了一种七糖的结构,该结构被认为代表了百日咳博德特氏菌内毒素脂多糖1的疏水(脂质A)部分紧邻的区域。这种七糖占完整多糖结构的50%至60%。
