Bridging Bacteria and the Gut: Functional Aspects of Type IV Pili [PDF]

Trends in Microbiology, 2020
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 human ecosystems.

The ‘porin-cytochrome’ model for microbe-to-mineral electron transfer [PDF]

, 2012
Many species of bacteria can couple anaerobic growth to the respiratory reduction of insoluble minerals containing Fe(III) or Mn(III/IV). It has been suggested that in Shewanella species electrons cross the outer membrane to extracellular substrates via ‘

Gram-Positive Type IV Pili and Competence

Microbiology Spectrum, 2019
ABSTRACT Type IV pili (T4P) are remarkable bacterial surface appendages that carry out a range of functions. Various types of T4P have been identified in bacteria and archaea, making them almost universal structures in prokaryotes.

Electrochemical reduction of oxygen catalyzed by Pseudomonas aeruginosa [PDF]

, 2010
Pseudomonas aeruginosa has already been shown to catalyze oxidation processes in the anode compartment of a microbial fuel cell. The present study focuses on the reverse capacity of the bacterium, i.e. reduction catalysis. Here we show that P. aeruginosa

Exceptionally widespread nanomachines composed of type IV pilins: the prokaryotic Swiss Army knives

, 2014
Prokaryotes have engineered sophisticated surface nanomachines that have allowed them to colonize Earth and thrive even in extreme environments. Filamentous machineries composed of type IV pilins, which are associated with an amazing array of properties ...

Pea broth enhances the biocontrol efficacy of Lysobacter capsici AZ78 by triggering cell motility associated with biogenesis of type IV pilus

Frontiers in Microbiology, 2016
Bacterial cells can display different types of motility, due to the presence of external appendages such as flagella and type IV pili. To date, little information on the mechanisms involved in the motility of the Lysobacter species has been available ...

Cryo-electron microscopy reveals two distinct type IV pili assembled by the same bacterium

Nature Communications, 2020
Type IV pili are flexible filaments on the surface of bacteria, consisting of a helical assembly of pilin proteins. Here, Neuhaus et al. show that the bacterium Thermus thermophilus produces two forms of type IV pilus, differing in structure, protein ...

Identification of surprisingly diverse type IV pili, across a broad range of gram-positive bacteria. [PDF]

PLoS ONE, 2011
In Gram-negative bacteria, type IV pili (TFP) have long been known to play important roles in such diverse biological phenomena as surface adhesion, motility, and DNA transfer, with significant consequences for pathogenicity.

How bacterial cells and colonies move on solid substrates

, 2019
Many bacteria rely on active cell appendages, such as type IV pili, to move over substrates and interact with neighboring cells. Here, we study the motion of individual cells and bacterial colonies, mediated by the collective interactions of multiple ...

Genome sequence of the pattern forming Paenibacillus vortex bacterium reveals potential for thriving in complex environments [PDF]

, 2010
Background: The pattern-forming bacterium Paenibacillus vortex is notable for its advanced social behavior, which is reflected in development of colonies with highly intricate architectures.
