Iron is an indispensable metabolic cofactor in both pro-and eukaryotes, which engenders a
natural competition for the metal between bacterial pathogens and their human or animal …

The anaerobic Gram-negative bacterium Porphyromonas gingivalis is considered the
keystone of periodontitis diseases, a set of inflammatory conditions that affects the tissues …

Many bacteria use the flagellum for locomotion and chemotaxis. Its bidirectional rotation is
driven by a membrane-embedded motor, which uses energy from the transmembrane ion …

The bacterial flagellum is the prototypical protein nanomachine and comprises a rotating
helical propeller attached to a membrane-embedded motor complex. The motor consists of a …

Membrane proteins reside in lipid bilayers and are typically extracted from this environment
for study, which often compromises their integrity. In this work, we ejected intact assemblies …

The human large intestine is populated by a high density of microorganisms, collectively
termed the colonic microbiota, which has an important role in human health and nutrition …

Iron is a transition metal utilized by nearly all forms of life for essential cellular processes,
such as DNA synthesis and cellular respiration. During infection by bacterial pathogens, the …

Pseudomonas aeruginosa is a ubiquitous bacterium found in many natural and man‐made
environments. It is also a pathogen for plants, animals, and humans. As for almost all living …

Electron paramagnetic resonance (EPR) spectroscopy combined with site-directed spin
labelling is applicable to biomolecules and their complexes irrespective of system size and …

In the 1960s several groups reported the isolation and preliminary genetic mapping of
Escherichia coli strains tol erant towards the action of colicins. These pioneering studies kick …
