Abstract: | By various chemical procedures including ninhydrin-degradation it is shown that the as of yet unknown compound found in partial acid hydrolysates of isolated cell walls of Methanobacterium thermoautotrophicum and other species of this genus is 2-amino-2-deoxy-taluronic acid (N-Acetyltalosaminuronic acid) together with N-acetylglucosamine. It forms the glycan moiety of pseudomurein.Abbreviations PEP phosphoenolpyruvate - UDP-GlcNAc uridindiphospho-N-acetylglucosamine - MurNAc N-acetylmuramic acid - NAcTalNUA N-acetyltalosaminuronic acid |
