Scientists are studying how bacteria move across surfaces -- a process known as twitching motility. New findings led to the surprising discovery of the key role surface properties play in either ...
Type IV pili are ubiquitous bacterial motors that power surface motility. In peritrichously piliated species, it is unclear how multiple pili are coordinated to generate movement with directional ...
Type IV pili (T4P) are fascinating supermolecular machines that drive twitching motility, protein secretion, and DNA uptake in prokaryotes. T4P work as grappling hooks that cause bacterial twitching ...
L. Talà et al., “Pseudomonas aeruginosa orchestrates twitching motility by sequential control of type IV pili movements,” Nat Microbiol, 4:774–80, 2019. Bacteria use long, threadlike attachments known ...
Many disease-causing bacteria such as Pseudomonas aeruginosa crawl on surfaces through a walk-like motility known as "twitching". Nanometers-wide filaments called type IV pili are known to power ...
Megan O'Hara graduated in May after double majoring in microbiology with a dual degree in biomedical biological sciences and a minor in chemistry. In addition to receiving two awards from the ...
New light has been shed on dynamics of asymmetric type IV pili distribution and twitching motility triggered by directional light in cyanobacteria. Type IV pili (T4P) are fascinating supermolecular ...
