Shearing and Enrichment of Extracellular Type IV Pili [PDF]

, 2017
Pili are widespread among bacteria. Type IVa pili (T4aP) are associated with a variety of bacterial functions, including adhesion, motility, natural transformation, biofilm formation, and force-dependent signaling. In pathogenic bacteria, T4aP play a crucial role during infection and have been the subject of hundreds of studies.

Identification of an additional minor pilin essential for piliation in the archaeon Methanococcus maripaludis. [PDF]

PLoS ONE, 2013
Methanococcus maripaludis is an archaeon with two studied surface appendages, archaella and type IV-like pili. Previously, the major structural pilin was identified as MMP1685 and three additional proteins were designated as minor pilins (EpdA, EpdB and ...

Identification of a system required for the functional surface localization of sugar binding proteins with class III signal peptides in Sulfolobus solfataricus [PDF]

, 2007
The hyperthermophilic archaeon Sulfolobus solfataricus contains an unusual large number of sugar binding proteins that are synthesized as precursors with a class III signal peptide.

Bacteria use type-IV pili to slingshot on surfaces [PDF]

Proceedings of the National Academy of Sciences, 2011
Bacteria optimize the use of their motility appendages to move efficiently on a wide range of surfaces prior to forming multicellular bacterial biofilms. The “twitching” motility mode employed by many bacterial species for surface exploration uses type-IV pili (TFP) as linear actuators to enable directional crawling.

Appendages of the Cyanobacterial Cell

Life, 2015
Extracellular non-flagellar appendages, called pili or fimbriae, are widespread in gram-negative bacteria. They are involved in many different functions, including motility, adhesion, biofilm formation, and uptake of DNA.

Bacterial flagella hijack type IV pili proteins to control motility. [PDF]

Proc Natl Acad Sci U S A
Bacterial flagella and type IV pili (TFP) are surface appendages that enable motility and mechanosensing through distinct mechanisms. These structures were previously thought to have no components in common. Here, we report that TFP and some flagella share proteins PilO, PilN, and PilM, which we identified as part of the ...

Alternative mechanism for bacteriophage adsorption to the motile bacterium Caulobacter crescentus [PDF]

, 2011
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.

Subinhibitory concentrations of trimethoprim and sulfamethoxazole prevent biofilm formation by Acinetobacter baumannii through inhibition of Csu pilus expression [PDF]

, 2017
Acinetobacter baumannii is emerging as a multidrug-resistant nosocomial pathogen of increasing threat to human health worldwide. Pili are important bacterial virulence factors, playing a role in attachment to host cells and biofilm formation.

Characterization of Zoospore Type IV Pili in Actinoplanes missouriensis. [PDF]

J Bacteriol, 2019
Bacterial zoospores are interesting cells in that their physiological state changes dynamically: they are dormant in sporangia, show temporary mobility after awakening, and finally stop swimming to germinate in niches for vegetative growth. However, the cellular biology of a zoospore remains largely unknown.

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 ‘
