Figure 8

Typical peptidoglycan structure of Gram-positive bacteria, showing lysin cleavage sites. The cleavage sites are indicated: (1) N-acetyl-β-D-muramidase (lysozymes), (2) lytic transglycosylase, (3) N-acetyl-β-D-glucosaminidase, (4) N-acetylmuramoyl-L-alanine amidases, and (5) endopeptidase. Abbreviations: GlcNAc (N-acetyl glucosamine), MurNAc (N-acetyl muramic acid).
