Polar secretion of proteins via the Xcp type II secretion system in Pseudomonas aeruginosa.
The subcellular localization of the major type II secretion system of Pseudomonas aeruginosa, the Xcp system, was studied microscopically using a biarsenical ligand that becomes fluorescent upon binding to a tetracysteine motif (Lumio tag), which was fused to several Xcp components. Fusion of the Lumio tag to the C termini of the XcpR and XcpS proteins did not affect the functionality of these ...
متن کاملStructural study of ExsA, the regulator of Type III Secretion System of Pseudomonas aeruginosa
The Type III secretion system (T3SS) of Pseudomonas aeruginosa uses a needle-like protein apparatus to detect eukaryotic host cells and translocate effectors directly into the host cell. The effectors are also known as cytotoxins, which cause disruption of a series of signaling events in the host cell, facilitating the infection by P. aeruginosa. As the T3SS is antigenic and the expression of T...
متن کاملStructure and Function of the Type III Secretion System of Pseudomonas aeruginosa
Pseudomonas aeruginosa is a dangerous pathogen particularly because it harbors multiple virulence factors. It causes several types of infection, including dermatitis, endocarditis, and infections of the urinary tract, eye, ear, bone, joints and, of particular interest, the respiratory tract. Patients with cystic fibrosis, who are extremely susceptible to Pseudomonas infections, have a bad progn...
متن کاملNMR characterization of the Type III Secretion System Tip Chaperone Protein PcrG of Pseudomonas aeruginosa
Lung infection with Pseudomonas aeruginosa is the leading cause of death among cystic fibrosis patients. To initiate infection, P. aeruginosa assembles a protein nanomachine, the type III secretion system (T3SS) to inject bacterial proteins directly into target host cells. An important regulator of the P. aeruginosa T3SS is the chaperone protein PcrG, which forms a complex with the tip protein,...
متن کاملFunctional domains of ExsA, the transcriptional activator of the Pseudomonas aeruginosa type III secretion system.
The opportunistic pathogen Pseudomonas aeruginosa utilizes a type III secretion system (T3SS) to evade phagocytosis and damage eukaryotic cells. Transcription of the T3SS regulon is controlled by ExsA, a member of the AraC/XylS family of transcriptional regulators. These family members generally consist of an approximately 100-amino acid carboxy-terminal domain (CTD) with two helix-turn-helix D...
