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

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.

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.

Type IV pili: dynamics, biophysics and functional consequences
Nature Reviews Microbiology, 2019The surfaces of many bacteria are decorated with long, exquisitely thin appendages called type IV pili (T4P), dynamic filaments that are rapidly polymerized and depolymerized from a pool of pilin subunits. Cycles of pilus extension, binding and retraction enable T4P to perform a phenomenally diverse array of functions, including twitching motility, DNA

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

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 Minor Pilins Are Incorporated into Type IV Pili
Journal of Molecular Biology, 2010Type IV pili are long filamentous appendages required for both adhesion and a unique form of motility known as twitching. Twitching motility involves the extension and retraction of the pilus and requires a number of gene products, including five conserved pilin-like proteins of unknown function (FimU, PilV, PilW, PilX, and PilE in Pseudomonas ...

The Regulation and Dynamics of Type IV Pili
2021Type IV pili (T4P) are hair-like adhesins involved in many processes, including surface attachment, twitching, DNA uptake, electron transfer, and pathogenesis. These flexible filaments are expressed in various pathogens, including the opportunistic pathogen Pseudomonas aeruginosa.
