  2. Peptidoglycan - Wikipedia

    en.wikipedia.org/wiki/Peptidoglycan

    Peptidoglycan hydrolysis and synthesis are two processes that must occur in order for cells to grow and multiply, a technique carried out in three stages: clipping of current material, insertion of new material, and re-crosslinking of existing material to new material.

  3. Lysozyme - Wikipedia

    en.wikipedia.org/wiki/Lysozyme

    Peptidoglycan is the major component of gram-positive bacterial cell wall. [1] This hydrolysis in turn compromises the integrity of bacterial cell walls causing lysis of the bacteria. Lysozyme is abundant in secretions including tears , saliva , human milk , and mucus .

  4. 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.

  5. Periplasm - Wikipedia

    en.wikipedia.org/wiki/Periplasm

    As shown in the figure to the right, the periplasmic space in gram-negative or diderm bacteria is located between the inner and outer membrane of the cell. The periplasm contains peptidoglycan and the membranes that enclose the periplasmic space contain many integral membrane proteins, which can participate in cell signaling.

  9. Lysin - Wikipedia

    en.wikipedia.org/wiki/Lysin

    The lysin catalytic domain digests peptidoglycan locally at a high rate, which causes holes in the cell wall. Since the cross-linked peptidoglycan cell wall is the only mechanism that prevents the spontaneous burst of bacterial cells due to the high internal pressure (3 to 5 atmospheres), enzymatic digestion by lysins irreversibly causes ...
