Figure 3.

Graphical representation of selected muropeptides identified in P. aeruginosa PAO1. Typical muropeptide characteristics included monomers, dimers, trimers, and tetramers. Dimers were determined to be either 3–4 or 3–3 cross-linked between muropeptide monomers. Muropeptide modifications included amino acid substitutions in the fourth and/or fifth position of the peptide side chain, as well as the resultant muropeptide products after deacetylase or amidase activity.
