  2. Peptidoglycan - Wikipedia

    en.wikipedia.org/wiki/Peptidoglycan

    Peptidoglycan recognition is an evolutionarily conserved process. [25] The overall structure is similar between bacterial species, but various modifications can increase the diversity. These include modifications of the length of sugar polymers, modifications in the sugar structures, variations in cross-linking or substitutions of amino acids ...

  3. Lysozyme - Wikipedia

    en.wikipedia.org/wiki/Lysozyme

    It is a glycoside hydrolase that catalyzes the following process: Hydrolysis of (1→4)-β-linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in a peptidoglycan and between N-acetyl-D-glucosamine residues in chitodextrins. Peptidoglycan is the major component of gram-positive bacterial cell wall. [1]

  4. Lysin - Wikipedia

    en.wikipedia.org/wiki/Lysin

    Double-stranded DNA phage lysins tend to lie within the 25 to 40 kDa range in terms of size. A notable exception is the streptococcal PlyC endolysin, which is 114 kDa. PlyC is not only the biggest and most potent lysin, but also structurally unique since it is composed of two different gene products, PlyCA and PlyCB, with a ratio of eight PlyCB subunits for each PlyCA in its active conformation.

  5. N-Acetylglucosamine - Wikipedia

    en.wikipedia.org/wiki/N-Acetylglucosamine

    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.

  6. OBPgp279 - Wikipedia

    en.wikipedia.org/wiki/OBPgp279

    Since bacterial cell walls do not contain chitin, OBPgp279 hydrolyzes β-1,4-linked GlcNAc in peptidoglycan. [2] The hydrolysis of β-1,4-linked GlcNAc is catalyzed by two glutamate residues in the active side, one acting as a general acid, and another acting as a general base. [6] There is limited detail on the catalytic mechanism of OBPgp279.

  8. CHAP domain - Wikipedia

    en.wikipedia.org/wiki/CHAP_domain

    Many of these proteins are uncharacterised, but it has been proposed that they may function mainly in peptidoglycan hydrolysis. The CHAP domain is found in a wide range of protein architectures; it is commonly associated with bacterial type SH3 domains and with several families of amidase domains.
