Type III secretion system
The type III secretion system (T3SS) is a membrane-embedded nanomachine found in several Gram-negative bacteria. Upon contact between bacteria and host cells, the syringe-like T3SS (Figure 1) transfers proteins termed effectors from the bacterial cytosol to the cytoplasm or the plasma membrane of a single target cell. This is a major difference from secretion systems that merely release molecul...
متن کاملSalmonella type III secretion-associated chaperones confer secretion-pathway specificity.
Type III protein secretion systems (TTSSs) are ancestrally related to the flagellar export system and are essential for the virulence of many bacteria pathogenic for humans, animals and plants. Most proteins destined to travel the TTSS pathway possess at least two domains that specifically target them to the secretion apparatus. One of the domains is located within the amino terminal first appr...
متن کاملSecretion of a pneumococcal type II secretion system pilus correlates with DNA uptake during transformation.
Streptococcus pneumoniae is a major human pathogen that successfully adapts to the host environment via an efficient uptake system for free DNA liberated from other organisms in the upper respiratory tract, facilitating immune evasion and drug resistance. Although the initial signaling events leading to pneumococcal competence for DNA transformation and the fate of DNA when it has been taken up...
متن کاملType VI secretion system sheaths as nanoparticles for antigen display.
The bacterial type 6 secretion system (T6SS) is a dynamic apparatus that translocates proteins between cells by a mechanism analogous to phage tail contraction. T6SS sheaths are cytoplasmic tubular structures composed of stable VipA-VipB (named for ClpV-interacting protein A and B) heterodimers. Here, the structure of the VipA/B sheath was exploited to generate immunogenic multivalent particles...
متن کاملBacterial secretion systems with an emphasis on the chlamydial Type III secretion system.
Numerous bacterial proteins exert their function outside the prokaryotic cell. To this end, both Gram-negative and Gram-positive bacteria have evolved specialized mechanisms to transport their proteins to the bacterial supernatant or host cell cytoplasm, so called secretion systems. These different strategies will be briefly discussed, followed by an in depth description of the Type III secreti...
