title: On the structure of the peptidoglycan of cell walls from Myxobacter AL-1 (myxobacterales).
abstract: Basically the peptidoglycan of Myxobater AL-1 consists of alternating beta-1,4-linked N-acetylglucosamic-N-acetylmuramic acid chains. After splitting the aminosugar backbone with a specific algal enzyme three subunits arise: a monomer, a dimer and a timer. Investigation of the monomer with specific enzymes and comparison of the degradation products to standards derived from other bacterial peptidoglycans suggest the following structure of the monomer peptide: L-alanyl-D-glutamic-L-meso-diaminopimelic-D-alanine. A D-alanyl-D-meso-diaminopimelic acid bond is the bridgebond between the peptides of the subunits.
