  2. Lysozyme - Wikipedia

    en.wikipedia.org/wiki/Lysozyme

    [43] [44] [45] Lysozyme is a commonly used enzyme for lysing gram positive bacteria. [46] Due to the unique function of lysozyme in which it can digest the cell wall and causes osmotic shock (burst the cell by suddenly changing solute concentration around the cell and thus the osmotic pressure), lysozyme is commonly used in lab setting to ...

  3. Glycoside hydrolase family 22 - Wikipedia

    en.wikipedia.org/wiki/Glycoside_hydrolase_family_22

    Lysozyme type C and alpha-lactalbumin are similar both in terms of primary sequence and structure, and probably evolved from a common ancestral protein. [12] Around 35 to 40% of the residues are conserved in both proteins as well as the positions of the four disulphide bonds. There is, however, no similarity in function.

  4. Lysis - Wikipedia

    en.wikipedia.org/wiki/Lysis

    Many species of bacteria are subject to lysis by the enzyme lysozyme, found in animal saliva, egg white, and other secretions. [1] Phage lytic enzymes produced during bacteriophage infection are responsible for the ability of these viruses to lyse bacterial cells. [2]

  5. Glycoside hydrolase - Wikipedia

    en.wikipedia.org/wiki/Glycoside_hydrolase

    In prokaryotes, they are found both as intracellular and extracellular enzymes that are largely involved in nutrient acquisition. One of the important occurrences of glycoside hydrolases in bacteria is the enzyme beta-galactosidase (LacZ), which is involved in regulation of expression of the lac operon in E. coli.

  6. Glycoside hydrolase family 24 - Wikipedia

    en.wikipedia.org/wiki/Glycoside_hydrolase_family_24

    The enzyme hydrolyses the 1,4-beta linkages between N-acetyl-D-glucosamine and N-acetylmuramic acid in peptidoglycan heteropolymers of prokaryotic cell walls. E. coli endolysin also functions in bacterial cell lysis and acts as a transglycosylase. The T4 lysozyme structure contains 2 domains, the interface between which forms the active-site cleft.

  7. Bacterial cell structure - Wikipedia

    en.wikipedia.org/wiki/Bacterial_cell_structure

    Beta-lactam antibiotics such as penicillin inhibit the formation of peptidoglycan cross-links in the bacterial cell wall. The enzyme lysozyme, found in human tears, also digests the cell wall of bacteria and is the body's main defense against eye infections.

  8. 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.

  9. Lysis buffer - Wikipedia

    en.wikipedia.org/wiki/Lysis_buffer

    Cell lysis is a critical step in the purification of enzymes from bacterial cells, various components are commonly included in lysing buffers to facilitate effective cell disruption and release of the target enzyme. These components include detergents, salts, and enzymes, each playing a specific role in the lysis process.
