The Archaellum of Methanospirillum hungatei is Electrically Conductive [PDF]
mBio, 2018 Here we report that the archaellum ofMethanospirillum hungateiis electrically conductive. Our analysis of the previously published archaellum structure suggests that a core of tightly packed phenylalanines is one likely route for electron conductance. This is the first demonstration that electrically conductive protein filaments (e-PFs) have evolved in

Assembly and Function of the Archaeal Motility Structure, the Archaellum [PDF]
Biophysical Journal, 2013 Most archaea posses a motility structure, called the archaellum that is mainly used for swimming, but can also play a role in adherence to surfaces. Although the archaellum functionally resembles the bacterial flagellum, its structure and assembly is reminiscent of bacterial type IV pili.We use the crenarchaeal archaellum of Sulfolobus acidocaldarius ...

Nitrosarchaeum haohaiensis sp. Nov. CL1<sup>T</sup>: Isolation and Characterisation of a Novel Ammonia-Oxidising Archaeon From Aquatic Environments. [PDF]
Environ Microbiol RepFollowing a 3.5‐year enrichment cultivation period, a rapid‐growing ammonia‐oxidising archaeon, designated CL1T, was isolated from the East China Sea. Strain CL1T represents a new species within the Nitrosarchaeum genus and is capable of effectively oxidising ammonia at both low and high concentrations through the GS‐GOGAT and GDH pathways. Furthermore,

The archaellum: a rotating type
Molecular Microbiology, 2013 SummaryMicrobes have evolved sophisticated mechanisms of motility allowing them to respond to changing environmental conditions. While this cellular process is well characterized in bacteria, the mode and mechanisms of motility are poorly understood in archaea.

Identification of novel components of the Ced and Ups systems in Saccharolobus islandicus REY15A. [PDF]
mLifeAbstract In Sulfolobales cells, transcription of the Ups (UV‐inducible pili of Sulfolobus) and Ced (Crenarchaeal system for exchange of DNA) genes is highly induced by DNA damage, and the two systems play key roles in pili‐mediated cell aggregation and chromosomal DNA import, respectively.

Cross-kymography analysis to simultaneously quantify the function and morphology of the archaellum
Biophysics and Physicobiology, 2018 In many microorganisms helical structures are important for motility, e.g., bacterial flagella and kink propagation in Spiroplasma eriocheiris. Motile archaea also form a helical-shaped filament called the 'archaellum' that is functionally equivalent to the bacterial flagellum, but structurally resembles type IV pili. The archaellum motor consists of 6-

High‐resolution archaellum structure reveals a conserved metal‐binding site [PDF]
EMBO reports, 2019 Many archaea swim by means of archaella. While the archaellum is similar in function to its bacterial counterpart, its structure, composition, and evolution are fundamentally different. Archaella are related to archaeal and bacterial type IV pili.

Identification of the first transcriptional activator of an archaellum operon in a euryarchaeon [PDF]
Molecular Microbiology, 2016 SummaryThe archaellum is the swimming organelle of the third domain, the Archaea. In the euryarchaeon Methanococcus maripaludis, genes involved in archaella formation, including the three archaellins flaB1, flaB2 and flaB3, are mainly located in the fla operon.
