Peptidoglycan. The peptidoglycan layer within the bacterial cell wall is a crystal lattice structure formed from linear chains of two alternating amino sugars, namely N-acetylglucosamine (GlcNAc or NAG) and N-acetylmuramic acid (MurNAc or NAM).
Autolysins breaks down old peptidoglycan which allows for the formation of newer peptidoglycan for cell growth and elongation. This is called cell wall turnover. [ 6 ] Autolysins do this by hydrolyzing the β-(1,4) glycosidic bond of the peptidoglycan cell wall and the linkage between N-acetylmuramoyl residues and L-amino acid residues of ...
Human, [18] [58] mouse, [57] and porcine [74] PGLYRP2 are enzymes, N-acetylmuramoyl-L-alanine amidases, that hydrolyze the amide bond between the MurNAc and L-alanine, the first amino acid in the stem peptide in bacterial cell wall peptidoglycan. The minimal peptidoglycan fragment hydrolyzed by PGLYRP2 is MurNAc-tripeptide. [58]
Muramyl dipeptide is a component of bacterial peptidoglycan, a recognition structure or activator for nucleotide-binding oligomerization domain 2 (NOD2) protein. [1] It is a constituent of both Gram-positive and Gram-negative bacteria composed of N-acetylmuramic acid linked by its lactic acid moiety to the N-terminus of an L-alanine D-isoglutamine dipeptide.

This layered structure is called peptidoglycan (formerly called murein). GlcNAc is the monomeric unit of the polymer chitin, which forms the exoskeletons of arthropods like insects and crustaceans. It is the main component of the radulas of mollusks, the beaks of cephalopods, and a major component of the cell walls of most fungi.
Peptidoglycan binding domains have a general peptidoglycan binding function and a common core structure consisting of a closed, three-helical bundle with a left-handed twist. It is found at the N or C terminus of a variety of enzymes involved in bacterial cell wall degradation.
