Spatio-temporal dynamics of the proton motive force on single bacterial cells

A. Biquet-Bisquert, B. Carrio, N. Meyer, T. F. D. Fernandes, M. Abkarian, F. Seduk, A. Magalon, A. L. Nord, F. Pedaci

This study investigates the spatio-temporal dynamics of the proton motive force (PMF) in single bacterial cells using light-activated proton pumps and flagellar motors, revealing rapid homogenization and fast temporal changes.

Relaxation time asymmetry in stator dynamics of the bacterial flagellar motor

R. Perez-Carrasco, M.-J. Franco-Onate, J.-C. Walter, J. Dorignac, F. Geniet, J. Palmeri, A. Parmeggiani, N.-O. Walliser, A. L. Nord

The paper investigates stator dynamics in bacterial flagellar motors, revealing a stoichiometry-dependent asymmetry in remodeling kinetics that is best explained by a two-state catch-bond mechanism.

A catch-bond drives stator mechanosensitivity in the Bacterial Flagellar Motor

A. L. Nord, E. Gachon, R. Perez-Carrasco, J. A. Nirody, A. Barducci, R. M. Berry, F. Pedaci

The paper measures stator unit dynamics in bacterial flagellar motors under varying loads, finding that dissociation rates decrease with load, suggesting a catch-bond mechanism for mechano-sensitivity.

Impact of fluorescent protein fusions on the bacterial flagellar motor

M. Heo, A. L. Nord, D. Chamousset, E. van Rijn, B. J. E. Beaumont, F. Pedaci

This paper investigates how fluorescent protein fusions affect the bacterial flagellar motor's dynamics and shows that linker insertion can mitigate these effects.
