Abstract
  1. The identities of the component glycerol glucosides of the wall teichoic acids of Lactobacillus plantarum N.I.R.D. C106 have been confirmed by methylation analysis. These glucosides are alpha-d-glucopyranosyl-(1-->1)-l-glycerol, alpha-d-glucopyranosyl-(1-->2)-alpha-d-glucopyranosyl-(1-->1)-l-glycerol and alpha-d-glucopyranosyl-(1-->3)-alpha-d-glucopyranosyl-(1-->1)-l-glycerol. 2. These units are connected by phosphodiester groups attached to the 3(l)-hydroxyl group of glycerol and the 6-hydroxyl group of the non-reducing terminal glucose residues in the adjacent unit. 3. Concanavalin A forms a precipitate with the teichoic acid and the material so precipitated contains only the alpha-d-glucopyranosyl-(1-->2)-alpha-d-glucopyranosyl -(1-->1)-l-glycerol component. This unit is therefore present in a homogeneous polymer so that the teichoic acid is a mixture of this and of other possibly homogeneous chains containing the other two components.
摘要
  1. 通过甲基化分析已证实植物乳杆菌N.I.R.D. C106壁磷壁酸中组成甘油葡糖苷的结构。这些葡糖苷为α -D-吡喃葡萄糖基-(1→1)-L-甘油、α -D-吡喃葡萄糖基-(1→2)-α -D-吡喃葡萄糖基-(1→1)-L-甘油和α -D-吡喃葡萄糖基-(1→3)-α -D-吡喃葡萄糖基-(1→1)-L-甘油。2. 这些单元通过磷酸二酯基团相连,该基团连接到甘油的3(L)-羟基和相邻单元中非还原末端葡萄糖残基的6-羟基上。3. 伴刀豆球蛋白A与磷壁酸形成沉淀,如此沉淀的物质仅含有α -D-吡喃葡萄糖基-(1→2)-α -D-吡喃葡萄糖基-(1→1)-L-甘油成分。因此,该单元存在于一种均一聚合物中,使得磷壁酸为此成分与其他可能含有另外两种成分的均一链的混合物。
