Background Helicobacter pylori is well adapted to colonize the epithelial surface of the
human gastric mucosa and can cause persistent infections. In order to infect the gastric …

Flagellar motility of Campylobacter jejuni and Helicobacter pylori influences host
colonization by promoting migration through viscous milieus such as gastrointestinal mucus …

Highlights•The Helicobacter pylori chemotaxis system includes classical and auxiliary
chemotaxis proteins.•H. pylori senses several host and bacterial ligands through four …

Microbes use directed motility to colonize harsh and dynamic environments. We discovered
that Helicobacter pylori strains establish bacterial colonies deep in the gastric glands and …

Helicobacter pylori moves in response to environmental chemical cues using a chemotaxis
two-component signal-transduction system. Autoinducer-2 (AI-2) is a quorum-sensing signal …

The flagellar motor stator is an ion channel nanomachine that assembles as a ring of the
MotA5MotB2 units at the flagellar base. The role of accessory proteins required for stator …

Helicobacter pylori (H. pylori) is a pathogen contributing to peptic inflammation, ulceration,
and cancer. A crucial step in the pathogenic sequence is when the bacterium first interacts …

Summary pH sensing is crucial for survival of most organisms, yet the molecular basis of
such sensing is poorly understood. Here, we present an atomic resolution structure of the …

In most signal transduction systems, coupling or scaffold proteins establish crucial
connections between receptors and histidine kinases. These connections are important for …

Microbes have chemotactic signaling systems that enable them to detect and follow
chemical gradients in their environments. The core of these sensory systems consists of …
