Lipopolysaccharide was isolated from bacteria Yersinia intermedia H9-36/83 (O:17) and degraded with mild acid to give an O-specific polysaccharide, which was isolated by GPC on Sephadex G-50 and studied by sugar analysis and 1D and 2D NMR spectroscopy. The polysaccharide was found to contain 3-deoxy-3-[(R)-3-hydroxybutanoylamino]-d-fucose (d-Fuc3NR3Hb) and the following structure of the heptasaccharide repeating unit was established: The structure established is consistent with the gene content of the O-antigen gene cluster. The O-polysaccharide structure and gene cluster of Y. intermedia are related to those of Hafnia alvei 1211 and Escherichia coli O:103.
从中间耶尔森菌H9-36/83(O:17)中分离出脂多糖,并用稀酸降解得到O-特异性多糖,通过在葡聚糖凝胶G-50上进行凝胶渗透色谱法(GPC)分离该多糖,并通过糖分析以及一维和二维核磁共振光谱进行研究。发现该多糖含有3-脱氧-3-[(R)-3-羟基丁酰氨基]-D-岩藻糖(d-Fuc3NR3Hb),并确定了七糖重复单元的以下结构:所确定的结构与O-抗原基因簇的基因内容一致。中间耶尔森菌的O-多糖结构和基因簇与蜂房哈夫尼亚菌1211和大肠杆菌O:103的相关。
