The O-specific polysaccharide was isolated from the lipopolysaccharide of Rheinheimera pacifica KММ 1406T and studied by chemical methods along with 1H and 13C NMR spectroscopy. It was shown that the polysaccharide contains one residue each of 2-acetamido-2-deoxy-D-galactose (D-GalNAc), 2-acetamido-2-deoxy-D- and 2-acetamido-2-deoxy-L-galacturonic acids (D-GalNAcA, L-GalNAcA), 2,4-diacetamido-2,4,6-trideoxy-D-glucose (D-QuiNAc4NAc), and 4-(N-acetyl-D-alanyl)amino-4,6-dideoxy-D-glucose (D-Qui4NAlaAc) and has the following structure: →4)-α-D-GalpNAc-(1→4)-α-L-GalpNAcA-(1→3)-β-D-QuipNAc4NAc-(1→2)-β-D-Quip4NDAlaAc-(1→4)-α-D-GalpNAcA-(1→
从太平洋莱茵海默氏菌KММ 1406T的脂多糖中分离出O-特异性多糖，并采用化学方法以及1H和13C核磁共振光谱对其进行了研究。结果表明，该多糖含有一个2-乙酰氨基-2-脱氧-D-半乳糖（D-GalNAc）、2-乙酰氨基-2-脱氧-D-和2-乙酰氨基-2-脱氧-L-半乳糖醛酸（D-GalNAcA、L-GalNAcA）、2,4-二乙酰氨基-2,4,6-三脱氧-D-葡萄糖（D-QuiNAc4NAc）和4-(N-乙酰-D-丙氨酰)氨基-4,6-二脱氧-D-葡萄糖（D-Qui4NAlaAc）残基，其结构如下：→4)-α-D-GalpNAc-(1→4)-α-L-GalpNAcA-(1→3)-β-D-QuipNAc4NAc-(1→2)-β-D-Quip4NDAlaAc-(1→4)-α-D-GalpNAcA-(1→
