The primary structure of the glycan moiety of pseudomurein from Methanobacterium thermoautotrophicum

H König et al. Hoppe Seylers Z Physiol Chem. 1983 Jun.

Abstract

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.
