Archaeal swimming motility is driven by archaella: rotary motors attached to long extracellular filaments. The structure of these motors, and particularly how they are anchored in the absence of a peptidoglycan cell wall, is unknown. Here, we use electron cryotomography to visualize the archaellar basal body in vivo in Thermococcus kodakaraensis KOD1. Compared to the homologous bacterial type IV pilus (T4P), we observe structural similarities as well as several unique features. While the… 

Positioning of the Motility Machinery in Halophilic Archaea

This work applied a combination of time-lapse imaging and fluorescence and electron microscopy using the model euryarchaeon Haloferax volcanii and found that archaella were specifically present at the cell poles of actively dividing rod-shaped cells, suggesting the presence of an active mechanism responsible for the positioning of macromolecular protein complexes in archaea.

Assembly, Functions and Evolution of Archaella, Flagella and Cilia

Salt‐dependent regulation of archaellins in Haloarcula marismortui

These findings indicate that in archaea, multiple encoded archaellins are not completely redundant, but in fact can display subtle functional differences, which enable cells to cope with varying environmental conditions.

Electron microscopic observations of prokaryotic surface appendages

Cryo-transmission electron microscopy is an essential tool for in situ structural analysis of microbes and their extracellular structures and recent advances in specimen preparation methods and image processing techniques have made cryo-Transmission electron microscope a essential tool.

The structure of the periplasmic FlaG–FlaF complex and its essential role for archaellar swimming motility

The structure of the FlaG–FlaF complexes from Sulfolobus acidocaldarius suggests that these proteins form a heterotetrameric complex in which FlaF regulates the filamentation of FlaG and anchoring of the archaellum to the S-layer, thereby modulating motility.

A comprehensive history of motility and Archaellation in Archaea

A historical overview on archaella and motility research in Archaea is provided, beginning with the first simple observations of motile extreme halophilic archaea a century ago up to state-of-the-art cryo-tomography of the archaellum motor complex and filament observed today.

An archaellum filament composed of two alternating subunits

Archaea use a molecular machine, called the archaellum, to swim. The archaellum consists of an ATP-powered intracellular motor that drives the rotation of an extracellular filament composed of

Twitch or swim: towards the understanding of prokaryotic motion based on the type IV pilus blueprint

This review of the recent structures of both the type IV pilus machinery and the archaellum determined in situ highlights the current level of functional understanding and discusses how this relates to the pressures facing bacteria and archaea throughout evolution.

ArlCDE form the archaeal switch complex

Fluorescent microscopy findings indicate that the euryarchaeal specific ArlCDE are part of the archaellum motor and that they directly receive input from the chemotaxis system via the adaptor protein CheF, and are essential for signal transduction during Chemotaxis and represent the Archaeal switch complex.



Structure and in situ organisation of the Pyrococcus furiosus archaellum machinery

Using combined modes of electron cryo-microscopy (cryoEM) and cryoEM, the structure of the Pyrococcus furiosus archaellum filament is solved and the architecture and organisation of its motor complex in situ is visualised, paving the way to a molecular understanding of archaeal swimming motion.

Direct observation of rotation and steps of the archaellum in the swimming halophilic archaeon Halobacterium salinarum

An advanced analysis method combined with total internal reflection fluorescence microscopy, termed cross-kymography, was developed and revealed a right-handed helical structure of archaella with a rotation speed of 23 ± 5 Hz, and the archaellar motor torque was estimated to be 50 pN’nm.

In situ structure of the complete Treponema primitia flagellar motor

The in situ structure of the complete flagellar motor from the spirochaete Treponema primitia is shown, using electron cryotomography of whole cells, and data suggest that both the carboxy-terminal and middle domains of FliG are found.

The archaellum: a rotating type IV pilus

A novel type of behaviour for type IV pilus like structures: archaella rotate and their rotation drives swimming motility is revealed, and it is demonstrated that temperature has a direct effect on rotation velocity explaining temperature‐dependent swimming velocity.

Assembly and function of the archaeal flagellum.

Understanding the assembly pathway and creating an interaction map of the molecular players in the archaeal flagellum will shed light on the details of the assembly and also the evolutionary relationship to the bacterial type IV pili-assembly systems.

CryoEM structure of the Methanospirillum hungatei archaellum reveals structural features distinct from the bacterial flagellum and type IV pilus

The structure reveals multiple post-translational modifications to the archaella, including six O-linked glycans and an unusual N-linked modification, which explain how the long but thin archaellum maintains the structural integrity required for motility-driving rotation.

Structural conservation of chemotaxis machinery across Archaea and Bacteria.

By electron cryotomography, it is found that the structure of both membrane-bound and cytoplasmic chemoreceptor arrays is conserved between Bacteria and Archaea, suggesting the fundamental importance of this signalling architecture across diverse prokaryotic lifestyles.

Identification of Archaea-specific chemotaxis proteins which interact with the flagellar apparatus

Results demonstrate that, in the archaeal domain, previously unrecognized archaea-specific Che proteins are essential for relaying taxis signaling to the flagellar apparatus.

Architecture of the type IVa pilus machine

Putting the known structures of the individual proteins in place like pieces of a three-dimensional puzzle revealed insights into how the T4PM machine works, including evidence that ATP hydrolysis by cytoplasmic motors rotates a membrane-embedded adaptor that slips pilin subunits back and forth from the membrane onto the pilus.
