The amino acid composition and structure of the peptidoglycan from Heliobacillus mobilis was determined by one‐ and two‐dimensional thin‐layer chromatography of completely and partially hydrolysed cell wall preparations. The structure was found to be of the A3γ type, with L,L‐diaminopimelate in position 3, d‐alanine in position 4 and a glycine interpeptide bridge, as found in certain groups of Gram‐positive bacteria including Clostridium perfringens and Nocardioides simplex . The presence of a Gram‐positive type of cell wall in heliobacteria is consistent with their phylogenetic relationship to the ‘low G + C’ Gram‐positive bacteria, as previously demonstrated by 16S rRNA sequencing.
