  2. Bacterial cell structure - Wikipedia

    en.wikipedia.org/wiki/Bacterial_cell_structure

    The bacterial cell wall differs from that of all other organisms by the presence of peptidoglycan which is located immediately outside of the cell membrane. Peptidoglycan is made up of a polysaccharide backbone consisting of alternating N-Acetylmuramic acid (NAM) and N-acetylglucosamine (NAG) residues in equal amounts.

  3. S-layer - Wikipedia

    en.wikipedia.org/wiki/S-layer

    For many bacteria, the S-layer represents the outermost interaction zone with their respective environment. [9] [2] Its functions are very diverse and vary from species to species. In many archaeal species the S-layer is the only cell wall component and, therefore, is important for mechanical and osmotic stabilization.

  4. Cell envelope - Wikipedia

    en.wikipedia.org/wiki/Cell_envelope

    The bacterial cell wall differs from that of all other organisms by the presence of peptidoglycan (poly-N-acetylglucosamine and N-acetylmuramic acid), which is located immediately outside of the cytoplasmic membrane. Peptidoglycan is responsible for the rigidity of the bacterial cell wall and for the determination of cell shape. It is ...

  5. Cell wall - Wikipedia

    en.wikipedia.org/wiki/Cell_wall

    A plant cell wall was first observed and named (simply as a "wall") by Robert Hooke in 1665. [3] However, "the dead excrusion product of the living protoplast" was forgotten, for almost three centuries, being the subject of scientific interest mainly as a resource for industrial processing or in relation to animal or human health.

  6. Bacteria - Wikipedia

    en.wikipedia.org/wiki/Bacteria

    Around the outside of the cell membrane is the cell wall. Bacterial cell walls are made of peptidoglycan (also called murein), which is made from polysaccharide chains cross-linked by peptides containing D-amino acids. [75] Bacterial cell walls are different from the cell walls of plants and fungi, which are made of cellulose and chitin ...

  7. Outer membrane vesicle - Wikipedia

    en.wikipedia.org/wiki/Outer_membrane_vesicle

    Surrounding this inner cell membrane there is a second bilayer called the bacterial outer membrane. The compartment or space between these two membranes is called the periplasm or periplasmic space. In addition, there is a firm cell wall consisting of peptidoglycan layer, which surrounds the cell membrane and occupies the periplasmic space. The ...

  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. Undecaprenyl phosphate - Wikipedia

    en.wikipedia.org/wiki/Undecaprenyl_phosphate

    That being said, the components necessary for the proper UP functioning can be inhibited, restricting the aiding of cell wall synthesis. As a result, the bacteria's structure is compromised, and its ability to combat lysing is lost. [2] On a larger scale, this is helpful when fighting, or preventing bacterial infections.
