Dynamic stiffening of the flagellar hook
Autor: Ashley L. Nord, Anaïs Biquet-Bisquert, Manouk Abkarian, Théo Pigaglio, Farida Seduk, Axel Magalon, Francesco Pedaci
Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-9 (2022)
Bacterial motility relies on the mechanics of the “hook” the 60 nm biopolymer at the base of rotating flagella. Here, authors observe the hook stiffening as it is twisted by the rotation of the flagellum, a mechanical feat evolved for its functio

The Dynamic Ion Motive Force Powering the Bacterial Flagellar Motor
Autor: Anaïs Biquet-Bisquert, Gilles Labesse, Francesco Pedaci, Ashley L. Nord
Publikováno v: Frontiers in Microbiology, Vol 12 (2021)
The bacterial flagellar motor (BFM) is a rotary molecular motor embedded in the cell membrane of numerous bacteria. It turns a flagellum which acts as a propeller, enabling bacterial motility and chemotaxis. The BFM is rotated by stator units, inner

Electrochemical gradients established across biological membranes are fundamental in the bioenergetics of all forms of life. In bacteria, the proton motive force (PMF), the electrochemical potential associated to protons, powers an impressive array o

The bacterial flagellar motor (BFM) is the membrane-embedded rotary molecular motor which turns the flagellum that provides thrust to many bacterial species. This large multimeric complex, composed of a few dozen constituent proteins, has emerged as

The bacterial flagellum is a macromolecular protein complex that enables motility in many species. Bacterial flagella self-assemble a strong, multicomponent drive shaft that couples rotation in the inner membrane to the micrometre-long flagellar fila

Dynamic stiffening of the flagellar hook
Autor: Ashley L. Nord, Anaïs Biquet-Bisquert, Manouk Abkarian, Théo Pigaglio, Farida Seduk, Axel Magalon, Francesco Pedaci
Many bacteria are motile by means of one or more rotating rigid helical flagella, making them the only known organism to use rotation as a means of propulsion. The rotation is supplied by the bacterial flagellar motor, a particularly powerful rotary
