Depending on pH growth conditions, the peptidoglycan forms around 40 to 90% of the cell wall's dry weight of gram-positive bacteria but only around 10% of gram-negative strains. Thus, presence of high levels of peptidoglycan is the primary determinant of the characterisation of bacteria as gram-positive. [5]
Peptidoglycan recognition proteins (PGRPs) are a group of highly conserved pattern recognition receptors with at least one peptidoglycan recognition domain capable of recognizing the peptidoglycan component of the cell wall of bacteria. They are present in insects, mollusks, echinoderms and chordates. The mechanism of action of PGRPs varies ...
Hydrolysis of peptidoglycan by PGLYRP2 diminishes peptidoglycan's pro-inflammatory activity. [ 31 ] [ 41 ] This effect is likely due to amidase activity of PGLYRP2, which separates the stem peptide from MurNAc in peptidoglycan and destroys the motif required for the peptidoglycan-induced activation of NOD2 (nucleotide-binding oligomerization ...

Glycopeptide antibiotics are a class of drugs of microbial origin that are composed of glycosylated cyclic or polycyclic nonribosomal peptides.Significant glycopeptide antibiotics include the anti-infective antibiotics vancomycin, teicoplanin, telavancin, ramoplanin, avoparcin and decaplanin, corbomycin, complestatin and the antitumor antibiotic bleomycin.
