Type IV pili facilitated natural competence in Fusobacterium nucleatum
Anaerobe, 2023Many bacterial species naturally take up DNA from their surroundings and recombine it into their chromosome through homologous gene transfer (HGT) to aid in survival and gain advantageous functions. Herein we present the first characterization of Type IV pili facilitated natural competence in Fusobacterium nucleatum, which is a Gram-negative, anaerobic

Dynamics of gonococcal type IV pili during infection
ChemPhysChem, 2009AbstractKeep that motor running: Type IV pili are among the strongest molecular motors characterized to date. Herein it is reported that pilus motors of the human pathogen Neisseria gonorrhoeae are very active for at least one day post‐infection of epithelial cells.

A novel ColV plasmid encoding type IV pili
Microbiology, 2003Many septicaemic Escherichia coli strains harbour ColV virulence plasmids. This paper describes pO78V, a conjugative ColV plasmid from an avian pathogenic E. coli strain that encodes type IV pili in addition to other virulence-related genes and tetracycline resistance. Plasmid location of type IV pili genes was demonstrated using Southern hybridization

Research in Microbiology, 2012
Archaea have evolved fascinating surface structures allowing rapid adaptation to changing environments. The archaeal surface appendages display such diverse biological roles as motility, adhesion, biofilm formation, exchange of genetic material and species-specific interactions and, in turn, increase fitness of the cells.

Type II Secretion and Type IV Pili of Francisella
Annals of the New York Academy of Sciences, 2007Abstract: Francisella tularensis genomes encode homologues of type IV pili. Though several F. tularensis genes required for Tfp expression are homologous to genes required for type II secretion (T2S), these gene clusters mainly bear structural signatures that are typical of Tfp. There is preliminary evidence that different F.

Purification of Type IV Pili and Pilin Subunits
2019The Type IV pili are displayed peritrichously on the surfaces of Neisseria gonorrhoeae cells. Here we present protocols for isolating and purifying Type IV pili and dissociating them into PilE pilin subunits. Pilus filaments are isolated from the bacterial cell surface by mechanical shearing and purified by differential precipitation and centrifugation.

Type IV pili‐mediated secretion modulates Francisella virulence
Molecular Microbiology, 2006Summary Francisella tularensis are the causative agent of the zoonotic disease, tularaemia. Among four F. tularensis subspecies, ssp. novicida (F. novicida) is pathogenic only for immunocompromised individuals, while all four subspecies are pathogenic for mice. This study utilized proteomic and bioinformatic approaches to identify seven F.

Type IV pili: functions and biogenesis.
2014AbstractPili (or fimbriae) are hair-like appendages that extend from the surface of many bacteria, and are polymers of primarily one protein generically named pilin. Out of the many types of pili that have been identified and classified according to their morphological and/or molecular characteristics, type IV pili (Tfp) are undoubtedly the most ...

How Bacteria Use Type IV Pili Machinery on Surfaces
Trends in Microbiology, 2015The bacterial type IV pilus (T4P) is a versatile molecular machine with a broad range of functions. Recent advances revealed that the molecular components and the biophysical properties of the machine are well conserved among phylogenetically distant bacterial species.

Pseudomonas aeruginosa Twitching Motility: Type IV Pili in Action
Annual Review of Microbiology, 2012Type IV pili (T4P) are one of the most common forms of bacterial and archaeal surface structures, involved in adherence, motility, competence for DNA uptake, and pathogenesis. Pseudomonas aeruginosa has emerged as one of the key model systems for the investigation of T4P structure and function.
