The Lrs14‐Like AbfR1 Homolog From Metallosphaera sedula Is a Nucleoid‐Organizing Protein
MicrobiologyOpen, Volume 14, Issue 5, October 2025.Nucleoid organization in Crenarchaeota involves diverse small DNA‐binding proteins. The Lrs14‐type protein AbfR1 from Metallosphaera sedula binds nonsequence specifically across the genome and induces DNA condensation. These findings suggest a structural role for AbfR1Ms in chromatin architecture, functionally resembling bacterial nucleoid‐associated ...

The one‐component system
Molecular Microbiology, 2013 SummaryLinking the motility apparatus to signal transduction systems enables microbes to precisely control their swimming behaviour according to environmental conditions. Bacteria have therefore evolved a complex chemotaxis machinery, which has presumably spread through lateral gene transfer into the euryarchaeal subkingdom.

Magnetite Nanoparticles Enhancing H2‐Driven Biomethanation in a Mixed Microbial Community
Global Challenges, Volume 9, Issue 9, September 2025.Supplementation of magnetite nanoparticles to a mixed microbial culture accelerates H2/CO2 biomethanation by up to 13‐fold. The observed enhancement is accompanied by a marked enrichment of Paracoccus sp., suggesting the establishment of a mutualistic interaction with hydrogenotrophic methanogens via interspecies electron transfer.

MicrobiologyOpen, Volume 8, Issue 9, September 2019., 2019 Cyclic di‐adenylate monophosphate (c‐di‐AMP) is an essential second messenger in bacteria, where it was demonstrated to have a central function in cellular osmoregulation. For archaea, currently little information on second messengers is available. This study proves that c‐di‐AMP is present in vivo in the archaeon Haloferax volcanii and demonstrates ...

Positioning of the Motility Machinery in Halophilic Archaea
mBio, 2019 Bacteria and archaea exhibit tactical behavior and can move up and down chemical gradients. This tactical behavior relies on a motility structure, which is guided by a chemosensory system.

Screening of a Haloferax volcanii Transposon Library Reveals Novel Motility and Adhesion Mutants
Life, 2016 Archaea, like bacteria, use type IV pili to facilitate surface adhesion. Moreover, archaeal flagella—structures required for motility—share a common ancestry with type IV pili.

Regulation of DNA Topology in Archaea: State of the Art and Perspectives
Molecular Microbiology, Volume 123, Issue 3, Page 245-264, March 2025.DNA topoisomerases are ubiquitous enzymes that play a crucial role in regulating DNA supercoiling which affects fundamental biological processes involving DNA. In this review, we summarize the current understanding of regulation of supercoiling by DNA topoisomerases in the third domain of life, the Archaea, with a particular focus on three key model ...
