一组脂寡糖 (LOS) 先前已在 M 中进行了表征。胃W471。高抗原性LOS(LOS-III)的结构已被阐明,该分子可以明确区分M。胃部来自机会致病菌M。堪萨斯州。在本研究中,其他三个M的结构。通过一维 1 H-NMR 光谱和气相色谱法测定gastri W471 LOS。它们的不同之处在于 Xylp 单元的数量和末端单糖的结构。二维 (2D) NMR 方法已成功应用于 M 的 LOS 抗原。 kansasii 定位乙酰基和酰基取代基并确定 α-d-Fucp 单元的异头构型。研究了抗 LOS-III 抗体的分子特异性,并将 LOS-III 表位定义为远端二糖:3,6-二脱氧-4-C-(1,3-二甲氧基-4,5,6,7-四羟基庚基)-α-xylohexp-(1 → 3)-β-l-Xylp。
A set of Lipooligosaccharides (LOSs) has previously been characterized inM. gastri W471. The structure of the highly antigenic LOS (LOS-III) was elucidated and this molecule can unambiguously distinguishM. gastri from the opportunistic pathogenM. kansasii. In the present study, the structures of three otherM. gastri W471 LOSs were determined by one-dimensional1H-NMR spectroscopy and gas liquid chromatography. They differ by the number of Xylp units and by the structure of the distal monosaccharide. The two dimensional (2D) NMR approach was successfully applied to the LOS antigen ofM. kansasii to locate the acetyl and acyl substituents and to determine the anomeric configuration of the α-d-Fucp unit.The molecular specificity of anti-LOS-III antibodies was investigated and the LOS-III epitope was defined as the distal disaccharide: 3,6-dideoxy-4-C-(1,3-dimethoxy-4,5,6,7-tetrahydroxy-heptyl)-α-xylohexp-(1 → 3)-β-l-Xylp.
