Bridging Bacteria and the Gut: Functional Aspects of Type IV Pili. [PDF]
Cell-surface-located proteinaceous appendages, such as flagella and fimbriae or pili, are ubiquitous in bacterial communities. Here, we focus on conserved type IV pili (T4P) produced by bacteria in the intestinal tract, one of the most densely populated ...

DIVERSITY AND EVOLUTION OF TYPE IV PILI SYSTEMS IN ARCHAEA [PDF]
Many surface structures in archaea including various types of pili and the archaellum (archaeal flagellum) are homologous to bacterial type IV pili systems (T4P).

Type IV pili facilitated natural competence in Fusobacterium nucleatum.
OBJECTIVES Many 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

SUMMARY We report here cryo-electron microscopy reconstructions of Type IV pili (T4P) from two important human pathogens, Pseudomonas aeruginosa and Neisseria gonorrhoeae, at ~ 8 Å and 5 Å resolution, respectively.

Type IV pili in Francisella – A virulence trait in an intracellular pathogen [PDF]
Francisella tularensis is a highly virulent intracellular human pathogen that is capable of rapid proliferation in the infected host. Mutants affected in intracellular survival and growth are highly attenuated which highlights the importance of the ...

Type IV pili mechanochemically regulate virulence factors in Pseudomonas aeruginosa [PDF]
Bacteria have evolved a wide range of sensing systems to appropriately respond to environmental signals. Here we demonstrate that the opportunistic pathogen Pseudomonas aeruginosa detects contact with surfaces on short timescales using the mechanical ...

Biofilm formation by Pseudomonas aeruginosa wild type, flagella and type IV pili mutants
Biofilm formation by Gfp-tagged Pseudomonas aeruginosa PAO1 wild type, flagella and type IV pili mutants in flow chambers irrigated with citrate minimal medium was characterized by the use of confocal laser scanning microscopy and comstat image analysis.

Analysis of pilus biogenesis genes in bacteria expressing type iv pili [PDF]
The structural and sequences similarities of type-IV pili proteins were analysed in Pseudomonas aeruginosa, Vibrio cholerae, Neisseria meningitidis and Neisseria gonorrhoeae.

Type IV Pili in Gram-Positive Bacteria [PDF]
SUMMARY Type IV pili (T4P) are surface-exposed fibers that mediate many functions in bacteria, including locomotion, adherence to host cells, DNA uptake (competence), and protein secretion and that can act as nanowires carrying electric current.

Type IV pili: paradoxes in form and function [PDF]
Type IV pili are filaments on the surfaces of many Gram-negative bacteria that mediate an extraordinary array of functions, including adhesion, motility, microcolony formation and secretion of proteases and colonization factors. Their prominent display on the surfaces of many bacterial pathogens, their vital role in virulence, and their ability to ...
