Abstract

The chemical structure of the surface polysaccharide from Staphylococcus aureus M was investigated by a combination of methanolytic, hydrolytic, and chromatographic techniques. The repeating unit that was most consistent with the data was a hexasaccharide composed of N-acetyl-D-aminogalacturonic acid, N-acetyl-D-fucosamine, and taurine in molar ratios of 4:2:1. A disaccharide was isolated and characterized, by combined gas-liquid chromatography-mass spectrometry, as N-acetyl-D-aminogalacturonyl-(1 leads to 3)-N-acetyl-D-fucosamine. Taurine is linked to a carboxyl group of N-acetyl-D-aminogalacturonic acid via an amide bond.

摘要

通过甲醇分解、水解和色谱技术相结合的方法,对金黄色葡萄球菌M表面多糖的化学结构进行了研究。与数据最相符的重复单元是一种六糖,由N-乙酰-D-氨基半乳糖醛酸、N-乙酰-D-岩藻糖胺和牛磺酸按4:2:1的摩尔比组成。通过气液色谱-质谱联用技术分离并鉴定出一种二糖,为N-乙酰-D-氨基半乳糖醛酸基-(1→3)-N-乙酰-D-岩藻糖胺。牛磺酸通过酰胺键与N-乙酰-D-氨基半乳糖醛酸的羧基相连。
