Functional and structural characterization of Serratia marcescens ExbB: determinants of the interaction with HasB/TonB

ExbBD is part of a cytoplasmic membrane molecular motor driven by the proton-motive force. It belongs to the larger family of motors involved in nutriment import across the outer membrane of Gram-negative bacteria (ExbBD), flagellar rotation (MotAB) or lat ...

Mechanotaxis directs Pseudomonas aeruginosa twitching motility

Alexandre Louis André Persat, Lorenzo Anton-Louis Talà, Xavier Jean-Yves Pierrat, Jose Negrete Jr, Joanne Netter Engel, Marco Julian Kühn

The opportunistic pathogen Pseudomonas aeruginosa explores surfaces using twitching motility powered by retractile extracellu-lar filaments called type IV pili (T4P). Single cells twitch by sequen-tial T4P extension, attachment, and retraction. How single ...

The evolution of the type VI secretion system as a disintegration weapon

The type VI secretion system (T6SS) is a nanomachine used by many bacteria to drive a toxin-laden needle into other bacterial cells. Although the potential to influence bacterial competition is clear, the fitness impacts of wielding a T6SS are not well und ...

Insights into flagellar function and mechanism from the squid-vibrio symbiosis

Stéphanie Kéren Cohen

Flagella are essential and multifunctional nanomachines that not only move symbionts towards their tissue colonization site, but also play multiple roles in communicating with the host. Thus, untangling the activities of flagella in reaching, interacting, ...

Pseudomonas aeruginosa orchestrates twitching motility by sequential control of type IV pili movements

Alexandre Louis André Persat, Lorenzo Anton-Louis Talà

Prokaryotes have the ability to walk on surfaces using type IV pili (TFP), a motility mechanism known as twitching(1,2). Molecular motors drive TFP extension and retraction, but whether and how these movements are coordinated is unknown(3). Here, we reveal ...

This paper investigate the causal relationships that exist between the motility, defined as the personal ability to be mobile (Kaufmann et al., 2015), and mobility behaviors. To do so, we use the first wave (2018) of the "national daily mobility panel" sur ...

Centriole assembly at a glance

Pierre Gönczy, Georgios Hatzopoulos

The centriole organelle consists of microtubules (MTs) that exhibit a striking 9-fold radial symmetry. Centrioles play fundamental roles across eukaryotes, notably in cell signaling, motility and division. In this Cell Science at a Glance article and accom ...
