The pili of Gram-negative bacteria are long extracellular polymers that mediate diverse functions, such as bacterial attachment, movement and substrate transport. There are five classes of pili in ...

Bacteria navigate on surfaces using a 'sense of touch' Date: August 5, 2021 Source: Ecole Polytechnique Fédérale de Lausanne Summary: Researchers have characterized a mechanism that allows ...

Bacteria are microscopic single-celled organisms that can be helpful, such as those that live in our guts, or harmful, such as flesh-eating bacteria.

Depiction of bacteriophage PP7 (orange) at the cell surface of Pseudomonas aeruginosa detaching the bacterium's pilus (blue). The researchers identified protein structures and interactions using ...

In contrast to EF-P, however, this protein reacts to the metabolism of the cell and adapts protein synthesis to the prevailing requirements through specific chemical modifications.

These bacteria have pilus motors, which are the key to the spiral waves. Pilus motors are molecular motors, which are attached to pili—thin, hair-like appendages present on the bacterial cell ...

Now, Johns Hopkins Medicine scientists say they have shed new light on how bacteria protect themselves from certain phage invaders—by seizing genetic material from weakened, dormant phages and ...

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 ...
