Surface resistance to SSVs and SIRVs in pilin deletions of Sulfolobus islandicus

Molecular Microbiology, Volume 113, Issue 4, Page 718-727, April 2020., 2020
Evolving SSV9‐resistant Sulfolobus islandicus revealed pilin deletions in host chromosomes that confer broad viral resistance. Pilins were found to be a point of adsorption for Sulfolobus rod‐shaped virus 8, while SSV9 was still able to adsorb, but not infect.

Whole‐genome comparison between the type strain of Halobacterium salinarum (DSM 3754T) and the laboratory strains R1 and NRC‐1

MicrobiologyOpen, Volume 9, Issue 2, February 2020., 2020
The genome of the Halobacterium salinarum type strain (91‐R6, DSM 3754) was compared at the DNA and protein levels to the genomes of two well‐studied laboratory strains, NRC‐1 and R1. The chromosomes and portions of the plasmids were very closely related. However, distinct homologs for proteins involved in motility and N‐glycosylation were encountered.

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 ...

N-Glycosylation Is Important for Halobacterium salinarum Archaellin Expression, Archaellum Assembly and Cell Motility

Frontiers in Microbiology, 2019
Halobacterium salinarum are halophilic archaea that display directional swimming in response to various environmental signals, including light, chemicals and oxygen. In Hbt. salinarum, the building blocks (archaellins) of the archaeal swimming apparatus (

Structural insights into the mechanism of archaellar rotational switching. [PDF]

Nat Commun, 2022
Signal transduction via phosphorylated CheY towards the flagellum and the archaellum involves a conserved mechanism of CheY phosphorylation and subsequent conformational changes within CheY. This mechanism is conserved among bacteria and archaea, despite

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.

Dynamics and Eco‐Genomics of Baltic Sea Nitrifiers: Seasonality, Niches, Interactions and Genomic Uniqueness

Environmental Microbiology, Volume 28, Issue 1, January 2026.
Nitrifiers in the Baltic Sea show persistent abundance in aphotic waters and late‐fall to winter photic zone increases positively correlated with nutrients and negatively with light and chlorophyll. Through selective enrichment, five novel ammonia‐oxidising archaea genomes were recovered, including the dominant aphotic taxon, which revealed overall ...
