  2. Bacterial secretion system - Wikipedia

    en.wikipedia.org/wiki/Bacterial_secretion_system

    Bacterial secretion systems are protein complexes present on the cell membranes of bacteria for secretion of substances. Specifically, they are the cellular devices used by pathogenic bacteria to secrete their virulence factors (mainly of proteins) to invade the host cells.

  3. Type VIII secretion system - Wikipedia

    en.wikipedia.org/wiki/Type_VIII_Secretion_System

    A Type VIII secretion system is a type of secretion system found within the inner and outer membranes of gram-negative bacteria. This system is also referred to as the curli biogenesis pathway or the extracellular nucleation-precipitation pathway .

  4. Type IV secretion system - Wikipedia

    en.wikipedia.org/wiki/Type_IV_secretion_system

    The bacterial type IV secretion system, also known as the type IV secretion system or the T4SS, is a secretion protein complex found in gram negative bacteria, gram positive bacteria, and archaea. It is able to transport proteins and DNA across the cell membrane. [1] The type IV secretion system is just one of many bacterial secretion systems.

  5. Type II secretion system - Wikipedia

    en.wikipedia.org/wiki/Type_II_secretion_system

    The type II secretion system is one of six protein secretory systems commonly found in Gram-negative bacteria, along with the type I, type III, and type IV secretion systems, as well as the chaperone/usher pathway, the autotransporter pathway/type V secretion system, and the type VI secretion system (some bacteria also utilize the type VII ...

  7. Secretion - Wikipedia

    en.wikipedia.org/wiki/Secretion

    The prototypic Type IVA secretion system is the VirB complex of Agrobacterium tumefaciens. [11] Protein members of this family are components of the type IV secretion system. They mediate intracellular transfer of macromolecules via a mechanism ancestrally related to that of bacterial conjugation machineries. [12] [13]

  8. Type VII secretion system - Wikipedia

    en.wikipedia.org/wiki/Type_VII_secretion_system

    Type VII secretion systems are bacterial secretion systems first observed in the phyla Actinomycetota and Bacillota. Bacteria use such systems to transport, or secrete, proteins into the environment. [1] The bacterial genus Mycobacterium uses type VII secretion systems (T7SS) to secrete proteins across their cell envelope. [2]

  9. Type VI secretion system - Wikipedia

    en.wikipedia.org/wiki/Type_VI_secretion_system

    The type VI secretion system (T6SS) is one of the bacterial secretion systems, membrane protein complexes, used by a wide range of gram-negative bacteria to transport effectors. Effectors are moved from the interior of a bacterial cell, across the membrane into an adjacent target cell.
