Schematic representation of muropeptides and peptidoglycan. (A) The archetypical structure of muropeptides consist of NAG-NAM disaccharides attached to a peptide chain containing 2- to 5 amino acid residues, typically: L-alanine, D-glutamic acid, mDAP/L-Lys, D-alanine, and D-alanine. (B) Diverse cleavage points of PG cleaving enzymes: glucosaminidases (pink), amidases (yellow), peptidases (blue), and muramidases (green) are shown.
