Group G hemolytic streptococcal cell walls which have been treated with trypsin are composed of a group-specific polysaccharide moiety and a mucopeptide matrix. The mucopeptide contains N-acetylglucosamine, N-acetylmuramic acid, alanine, glutamic acid, lysine, and glycine, a composition similar to that of other groups of streptococci. The Group G carbohydrate is composed of rhamnose, N-acetylgalactosamine, and galactose. Serological studies suggest that the monosaccharide of L-rhamnose is a major component of the determinant of antigenic specificity.
经胰蛋白酶处理的G群溶血性链球菌细胞壁由群特异性多糖部分和粘肽基质组成。粘肽含有N-乙酰葡糖胺、N-乙酰胞壁酸、丙氨酸、谷氨酸、赖氨酸和甘氨酸,其组成与其他组链球菌相似。G群碳水化合物由鼠李糖、N-乙酰半乳糖胺和半乳糖组成。血清学研究表明,L-鼠李糖的单糖是抗原特异性决定簇的主要成分。
