Motility is a central feature of many microorganisms and provides an efficient strategy to
respond to environmental changes. Bacteria and archaea have developed fundamentally …

How complex, multi-component macromolecular machines evolved remains poorly
understood. Here we reveal the evolutionary origins of the chemosensory machinery that …

Understanding the function of cellular machines requires a thorough analysis of the
structural elements that underline their function. Electron microscopy (EM) has been pivotal …

Each of the three Domains of life, Eukarya, Bacteria and Archaea, have swimming structures
that were all originally called flagella, despite the fact that none were evolutionarily related to …

The chemoreceptor array, a remarkably ordered supramolecular complex, is composed of
hexagonally packed trimers of receptor dimers networked by a histidine kinase and one or …

Nearly all motile bacterial cells use a highly sensitive and adaptable sensory system to
detect changes in nutrient concentrations in the environment and guide their movements …

MinD proteins are well studied in rod-shaped bacteria such as E. coli, where they display
self-organized pole-to-pole oscillations that are important for correct positioning of the Z-ring …

Vibrio cholerae, the causative agent of the acute diarrheal disease cholera, is able to thrive
in diverse habitats such as natural water bodies and inside human hosts. To ensure their …

The structure and function of two-component and chemotactic signaling and different
aspects related to the motility of bacteria and archaea are key research areas in modern …

Motile archaea swim by means of a molecular machine called the archaellum. This structure
consists of a filament attached to a membrane-embedded motor. The archaellum is found …
