Structural characterization of the type II secretion system of Aeromonas hydrophila
The exeC gene, found in the gram-negative bacteria Aeromonas hydrophila codes for a 31 kDa, three domain, bitopic inner membrane protein. The components of the ExeC protein include an amino-terminal cytoplasmic domain, a trans-membrane helix and two periplasmic domains. The two periplasmic domains …

Characterization of an Interaction Between the Pseudopilin XcpT and the Putative ATPase XcpR in the Type II Secretion System of Pseudomonas Aeruginosa
The secretion of alkaline phosphatase, phospholipase C, lipase, elastase, and exotoxin A are among several virulence factors that contribute to the opportunistic pathogenicity of Pseudomonas aeruginosa. The secretion of these exoproteins is achieved via the Type II secretion system. At least twelve …

Type IV Pili-Dependent Secretion of Biofilm Matrix Material Proteins in Clostridium perfringens
… to identify pilin mutants that are needed for secretion of the biofilm matrix and develop a functional model for a type II secretion system (T2SS) in C. perfringens. Protein tagging, western blot, and slot blot experiments were done to quantify protein secretion. After performing experiments …

Exoproteomics of the Pseudomonas aeruginosa biofilm matrix reveals the role of a novel secretion system
… of cells living in a matrix of their own secretions. Cells that would otherwise be susceptible to antimicrobials are protected by the modifications that they make, in concert, to their surroundings. Aggregates of as few as 64 cells begin to exhibit elevated tolerance to antibiotics and, …

A Simulation Approach to the Study of Bacterial Secretion Proteins
… the complex machinery associated with the type II secretion system (T2SS) polymerises inner membrane pseudopilin proteins into thin filaments, to export substrates such as toxins, hydrolases and cytochromes. Here, computational simulations were used to study proteins from the Klebsiella …

Studies on the architecture and on transferability of pathogenicity islands of uropathogenic Escherichia coli strain 536
… the Pix fimbriae, a phosphoglycerate transport system, an autotransporter, as well as for hypothetical proteins. Downstream of 'pheV, the K15 capsule determinant (kpsK15) of this strain is located. Structural analysis of the 20-kb kpsK15 locus revealed a so far unknown genetic organisation …
