Abstract

The structure of the O-specific polysaccharides of the lipopolysaccharides produced by Hafnia alvei strains ATCC 13337 and 1187 was reinvestigated. The position of phosphate group in the repeating units of the polysaccharides was established with the aid of 1H detected, 31P edited NMR spectra. According to the results obtained, the polysaccharides are teichoic acid-like polymers with the repeating units of the following structure: [formula: see text] where Acyl = D-3-hydroxylbutyryl, and 3-O-acetylation was approximately 30%.

摘要

对蜂房哈夫尼亚菌菌株ATCC 13337和1187产生的脂多糖的O-特异性多糖结构进行了重新研究。借助1H检测、31P编辑的核磁共振谱确定了多糖重复单元中磷酸基团的位置。根据所得结果，这些多糖是类磷壁酸聚合物，其重复单元具有以下结构：[化学式：见原文]，其中酰基=D-3-羟基丁酰基，且3-O-乙酰化程度约为30%。
