Assembly Mechanism of FCT Region Type 1 Pili in Serotype M6 Streptococcus pyogenes [PDF]
The human pathogen Streptococcus pyogenes produces diverse pili depending on the serotype. We investigated the assembly mechanism of FCT type 1 pili in a serotype M6 strain. The pili were found to be assembled from two precursor proteins, the backbone protein T6 and ancillary protein FctX, and anchored to the cell wall in a manner that requires both a ...

Pilicide ec240 Disrupts Virulence Circuits in Uropathogenic
Chaperone-usher pathway (CUP) pili are extracellular organelles produced by Gram-negative bacteria that mediate bacterial pathogenesis. Small-molecule inhibitors of CUP pili, termed pilicides, were rationally designed and shown to inhibit type 1 or P ...

Reversible adhesion by type IV pili leads to formation of permanent localized clusters
Summary: The formation of long-lived, multicellular clusters is a fundamental step in the physiopathology of many disease-causing bacteria. Experiments on abiotic surfaces suggest that bacterial colonization, including initial cluster formation, requires

Alternative mechanism for bacteriophage adsorption to the motile bacterium Caulobacter crescentus [PDF]
2D and 3D cryo-electron microscopy, together with adsorption kinetics assays of ϕCb13 and ϕCbK phage-infected Caulobacter crescentus, provides insight into the mechanisms of infection.

Regulation of production of type 1 pili among urinary tract isolates of Escherichia coli [PDF]
The piliation and hemagglutination properties of 54 consecutive Escherichia coli isolates from women with recurrent urinary tract infections were studied. Mannose-sensitive hemagglutination (MSHA) of guinea pig erythrocytes, characteristic of type 1-piliated bacteria, was produced by 75% of the isolates, 32% produced mannose-insensitive ...

The structure of the PapD-PapGII pilin complex reveals an open and flexible P5 pocket [PDF]
P pili are hairlike polymeric structures that mediate binding of uropathogenic Escherichia coli to the surface of the kidney via the PapG adhesin at their tips.

The pilin protein FimP from Actinomyces oris: crystal structure and sequence analyses. [PDF]
The Actinomyces oris type-1 pili are important for the initial formation of dental plaque by binding to salivary proteins that adhere to the tooth surface. Here we present the X-ray structure of FimP, the protein that is polymerized into the type-1 pilus

Integrin-mediated host cell invasion by type 1-piliated uropathogenic Escherichia coli.
Uropathogenic Escherichia coli (UPEC), the primary causative agent of urinary tract infections, typically express filamentous adhesive organelles called type 1 pili that mediate both bacterial attachment to and invasion of bladder urothelial cells ...

Speed switching of gonococcal surface motility correlates with proton motive force. [PDF]
Bacterial type IV pili are essential for adhesion to surfaces, motility, microcolony formation, and horizontal gene transfer in many bacterial species. These polymers are strong molecular motors that can retract at two different speeds.
