Bacteria differently deploy type-IV pili on surfaces to adapt to nutrient availability. NPJ Biofilms Microbiomes 2016; 2: 15029.Ni L, Yang S, Zhang RR, et al. Bacteria differently deploy type-IV pili on surfaces to adapt to nutrient availability. npj Biof Microb, 2016, 2: 15029....
In twitching motility, bacterial use their type IV pili as a grappling hook, repeatedly extending it, anchoring it and then retracting it with remarkable force (>80 pN).[123] Flagella are semi-rigid cylindrical structures that are rotated and function much like the propeller on a ship. Object...
In 2011, researchers used a high-speed camera to capture footage of bacteria. The cells used their natural, grappling hook-like structures, known as Type IV pili (TFP), to sling-shot from one surface to the next. The TFP is crucial to the movement of bacteria. Because bacteria are covere...
Pili are proteic retractile filaments up to 20 micrometer long that protrude from gram-negative bacteria. Some RNA and DNA bacteriophages use pili to attach to the host cell. There are many types of pili and each bacterial virus binds specifically to a precise type. Do all bacteria have pili?
and respond actively through flagella and pili or passively through mechanosensitive channels. Mechanical strain in the bacterial membrane affects intracellular protein localization and divisome dynamics. Osmotic pressure, resulting from differences in solute concentrations with the environment, can also induce ...
The grids were plunge frozen into liquid ethane using a Vitrobot Mark IV (Thermo Fisher Scientific). Cryo-EM data were collected on a Titan Krios transmission electron microscope (Thermo Fisher Scientific) equipped with a K2 Direct Detection Camera (BioQuantum), operated with 300 kV acceleration...
bacteriovorus bacteria invade their prey is not completely elucidated, but type IV pili have been implicated as essential in the process (5–7). Once inside, B. bacteriovorus grows in a filamentous manner by digesting the prey cell from within, divides into a number of progeny, and then lys...
Consistent with other Gracilibacteria, the WB Gracilibacteria expressed type IV pili systems, which can aid in the uptake of DNA from the environment [79, 80] and have been shown to be essential for host adhesion in the case of TM7i and its Leucobacter aridicollis host [81]. The DNA ...

Bacteria can exchange DNA through extracellular appendages (‘mating pili’) in a process known as conjugation. Here, Beltran et al. determine atomic structures by cryo-electron microscopy of a bacterial conjugative pilus and two archaeal pili, showing that the archaeal pili are homologous to bacteri...
