After treatment of isolated cells walls of Methanobacterium thermoautotrophicum with sodium hydroxide or anhydrous hydrazine, water soluble glycan strands were obtained. These consisted of alternating (beta 1-3)-linked D-glucosamine and (alpha 1-3)-linked L-talosaminuronic acid residues and their length was about 25 disaccharides. Some of the L-talosaminuronic acid residues remained linked to either glutamic acid or the peptides N-gamma-glutamylalanine and N epsilon-(gamma-glutamylalanyl)lysine, indicating that the peptide moiety of pseudomurein is bound to the carboxyl group of talosaminuronic acid via the amino group of glutamic acid.
用氢氧化钠或无水肼处理嗜热自养甲烷杆菌的分离细胞壁后，得到了水溶性聚糖链。这些聚糖链由交替的（β1-3）连接的D-葡糖胺和（α1-3）连接的L-塔罗糖胺糖醛酸残基组成，其长度约为25个二糖。一些L-塔罗糖胺糖醛酸残基仍与谷氨酸或肽N-γ-谷氨酰丙氨酸和Nε-（γ-谷氨酰丙氨酰）赖氨酸相连，这表明假肽聚糖的肽部分通过谷氨酸的氨基与塔罗糖胺糖醛酸的羧基结合。
