Cooperative retraction of bundled type IV pili enables nanonewton force generation.
PLoS Biology, 2008 The causative agent of gonorrhea, Neisseria gonorrhoeae, bears retractable filamentous appendages called type IV pili (Tfp). Tfp are used by many pathogenic and nonpathogenic bacteria to carry out a number of vital functions, including DNA uptake ...

Functional characterization of type IV pili expressed on diarrhea-associated isolates of Aeromonas species [PDF]
, 1999 Our past work has shown that long, flexible type IV pili (single or in bundles) are the predominant pili expressed on fecal isolates of diarrhea- associated species of Aeromonas (Aeromonas veronii biovar sobria and A. caviae).

PilY proteins: bimodular drivers of type IV pilus versatility
Trends in MicrobiologyType IV pili (T4P) are dynamic surface fibers that mediate diverse bacterial activities, including adhesion, twitching motility, horizontal gene transfer, biofilm formation, and virulence. The PilY family of T4P-associated proteins are found across a wide range of bacterial species and are critical for key T4P functions. PilY proteins are characterized

Functional and biochemical characterisation of remote homologues of type IV pili proteins PilN and PilO in Helicobacter pylori [PDF]
Helicobacter pylori encodes homologues of PilM, PilN and PilO from bacteria with Type IV pili, where these proteins form a pilus alignment complex. Inactivation of pilO changes H. pylori motility in semi-solid media, suggesting a link to the chemosensory
