Decoding the Chemical Language of Ribosomally Synthesized and Post‐Translationally Modified Peptides from the Untapped Archaea Domain

Angewandte Chemie, Volume 137, Issue 24, June 10, 2025.
Secondary metabolites (SMs) are essential across all life domains, yet those originating from the Archaea domain remain poorly understood. Here, the systematic genome mining and the pioneering heterologous expression of archaeal SMs have revealed the chemical landscape of archaeal lanthipeptides, showing both canonical and non‐canonical forms.

Bypassing the Need for the Transcriptional Activator EarA through a Spontaneous Deletion in the BRE Portion of the fla Operon Promoter in Methanococcus maripaludis

Frontiers in Microbiology, 2017
In Methanococcus maripaludis, the euryarchaeal archaellum regulator A (EarA) is required for the transcription of the fla operon, which is comprised of a series of genes which encode most of the proteins needed for the formation of the archaeal swimming ...

Tree of motility – A proposed history of motility systems in the tree of life

Genes to Cells, Volume 25, Issue 1, Page 6-21, January 2020., 2020
The known motilities are classified based on the unique classes of movement‐producing protein architectures. Based on this criterion, the current total of independent motility systems stands at 18 types. Presence or absence of a peptidoglycan layer, the acquisition of robust membrane dynamics, the enlargement of cells and environmental opportunities ...

Novel pili-like surface structures of Halobacterium salinarum strain R1 are crucial for surface adhesion

Frontiers in Microbiology, 2015
It was recently shown that haloarchaeal strains of different genera are able to adhere to surfaces and form surface-attached biofilms. However the surface structures mediating the adhesion were still unknown.

Molecular acclimation of Halobacterium salinarum to halite brine inclusions

Frontiers in Microbiology, 2023
Halophilic microorganisms have long been known to survive within the brine inclusions of salt crystals, as evidenced by the change in color for salt crystals containing pigmented halophiles.

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 nucleotide‐dependent interaction of FlaH and FlaI is essential for assembly and function of the archaellum motor [PDF]

Molecular Microbiology, 2015
SummaryThe motor of the membrane‐anchored archaeal motility structure, the archaellum, contains FlaX, FlaI and FlaH. FlaX forms a 30 nm ring structure that acts as a scaffold protein and was shown to interact with the bifunctional ATPase FlaI and FlaH. However, the structure and function of FlaH has been enigmatic.

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.

The one‐component system ArnR: a membrane‐bound activator of the crenarchaeal archaellum [PDF]

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.

Cyclic nucleotides in archaea: Cyclic di‐AMP in the archaeon Haloferax volcanii and its putative role

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 ...
