Abstract Two glycosyl 1-phosphate polymers containing monoglycosyl 1-phosphate, -6)-α-D-Glc p -(1- P. , and diglycosyl 1-phosphate, -6)-α-D-Gal p NAc-(1→6)-α-D-Glc p NAc-(1- P. , in the repeating unit were identified in the cell wall of Glutamicibacter protophormiae VKM Ac-2104 T (formerly, Arthrobacter protophormiae ). The structures of these polymers were described for the first time in prokaryotes. Teichulosonic acid, the third identified polymer, with 3-deoxy-D- glycero -α-D- galacto -non-2-ulopyranosonic acid (Kdn) and β-D-glucopyranose residues in the main chain, →6)-β-D-Glc p -(1→8)-α-Kdn-(2→, has been previously detected in a number of actinobacteria. The structures of these glycopolymers were established based on the results of chemical analysis and one-dimensional 1 H, 13 C, and 31 P NMR spectroscopy using two-dimensional homonuclear ( 1 H, 1 H COZY, TOCSY, ROESY) and heteronuclear ( 1 H, 13 C HSQC, HSQC-TOCSY, HMBC, and 1 H, 31 P HMBC) techniques.

两种糖基 1-磷酸聚合物和 Teichulosonic Acid 来自 Glutamicibacter protophormiae VKM Ac-2104T 细胞壁

摘要 两种含单糖基 1-磷酸酯的糖基 1-磷酸聚合物,-6)-α-D-Glc p -(1-P. 和二糖基 1-磷酸酯,-6)-α-D-Gal p NAc-(1 →6)-α-D-Glc p NAc-(1-P.,在原谷氨酸杆菌VKM Ac-2104 T(原原状节杆菌)细胞壁中重复单元被鉴定。描述了这些聚合物的结构第一次在原核生物中。Teichulosonic acid,第三种已鉴定的聚合物,主链中含有 3-脱氧-D-甘油-α-D-半乳糖-non-2-吡喃葡萄糖酸(Kdn)和β-D-吡喃葡萄糖残基, →6)-β-D-Glc p -(1→8)-α-Kdn-(2→, 之前已在许多放线菌中检测到。这些糖聚合物的结构是根据化学分析结果确定的和一维 1 H, 13 C,和 31 P NMR 光谱使用二维同核 ( 1 H, 1 H COZY, TOCSY, ROESY) 和异核 ( 1 H, 13 C HSQC, HSQC-TOCSY, HMBC 和 1 H, 31 P HMBC) 技术。
