  2. Bacterial cell structure - Wikipedia

    en.wikipedia.org/wiki/Bacterial_cell_structure

    An S-layer (surface layer) is a cell surface protein layer found in many different bacteria and in some archaea, where it serves as the cell wall. All S-layers are made up of a two-dimensional array of proteins and have a crystalline appearance, the symmetry of which differs between species.

  3. Pore-forming toxin - Wikipedia

    en.wikipedia.org/wiki/Pore-forming_toxin

    α-Hemolysin from S.aureus. Pore-forming proteins (PFTs, also known as pore-forming toxins) are usually produced by bacteria, and include a number of protein exotoxins but may also be produced by other organisms such as apple snails that produce perivitellin-2 [1] [2] or earthworms, who produce lysenin.

  4. Bacterial adhesin - Wikipedia

    en.wikipedia.org/wiki/Bacterial_adhesin

    FimH is a bacterial adhesin that helps bacteria such as Escherichia coli to bind to host cells and their receptors (here: the human proteins CD48 and TLR4, or mannose residues). [ 4 ] Most fimbria of gram-negative bacteria function as adhesins, but in many cases it is a minor subunit protein at the tip of the fimbriae that is the actual adhesin.

  5. Virulence factor - Wikipedia

    en.wikipedia.org/wiki/Virulence_factor

    Bacteria produce various adhesins including lipoteichoic acid, trimeric autotransporter adhesins and a wide variety of other surface proteins to attach to host tissue. Capsules, made of carbohydrate, form part of the outer structure of many bacterial cells including Neisseria meningitidis .

  6. Protein A - Wikipedia

    en.wikipedia.org/wiki/Protein_A

    Protein A is a 42 kDa surface protein originally found in the cell wall of the bacteria Staphylococcus aureus. It is encoded by the spa gene and its regulation is controlled by DNA topology, cellular osmolarity, and a two-component system called ArlS-ArlR. It has found use in biochemical research because of its ability to bind immunoglobulins ...

  7. M protein (Streptococcus) - Wikipedia

    en.wikipedia.org/wiki/M_protein_(Streptococcus)

    M protein is a virulence factor that can be produced by certain species of Streptococcus. [1] Viruses, parasites and bacteria are covered in protein and sugar molecules that help them gain entry into a host by counteracting the host's defenses. One such molecule is the M protein produced by certain streptococcal bacteria.

  8. Bacterial secretion system - Wikipedia

    en.wikipedia.org/wiki/Bacterial_secretion_system

    The general secretion (Sec) involves secretion of unfolded proteins that first remain inside the cells. In Gram-negative bacteria, the secreted protein is sent to either the inner membrane or the periplasm. But in Gram-positive bacteria, the protein can stay in the cell or is mostly transported out of the bacteria using other secretion systems.
