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.

Scale-up of biomass production by Methanococcus maripaludis

Frontiers in Microbiology, 2022
The development of a sustainable energy economy is one of the great challenges in the current times of climate crisis and growing energy demands. Industrial production of the fifth-generation biofuel methane by microorganisms has the potential to become ...

Hyperthermophilic methanogenic archaea act as high-pressure CH4 cell factories

Communications Biology, 2021
Mauerhofer et al. examine 80 species of methanogenic archaea at high pressures and evaluate growth and methane production, identifying Methanotorris igneus and Methanocaldococcoccus jannaschii as high-pressure methane cell factories.

The canonical single-stranded DNA-binding protein is not an essential replication factor but an RNA chaperon in Saccharolobus islandicus

iScience, 2023
Summary: Single-stranded DNA-binding proteins (SSBs) have been regarded as indispensable replication factors. Herein, we report that the genes encoding the canonical SSB (SisSSB) and the non-canonical SSB (SisDBP) in Saccharolobus islandicus REY15A are ...

CRISPR-Cas Adaptive Immune Systems of the Sulfolobales: Unravelling Their Complexity and Diversity

Life, 2015
The Sulfolobales have provided good model organisms for studying CRISPR-Cas systems of the crenarchaeal kingdom of the archaea. These organisms are infected by a wide range of exceptional archaea-specific viruses and conjugative plasmids, and their ...

Redox and Thiols in Archaea [PDF]

Antioxidants, 2020
Low molecular weight (LMW) thiols have many functions in bacteria and eukarya, ranging from redox homeostasis to acting as cofactors in numerous reactions, including detoxification of xenobiotic compounds. The LMW thiol, glutathione (GSH), is found in eukaryotes and many species of bacteria.

Metagenomes from Coastal Marine Sediments Give Insights into the Ecological Role and Cellular Features of Loki- and Thorarchaeota

mBio, 2019
The genomes of Asgard Archaea, a novel archaeal proposed superphylum, share an enriched repertoire of eukaryotic signature genes and thus promise to provide insights into early eukaryote evolution.

The transcriptional regulator EarA and intergenic terminator sequences modulate archaellation in Pyrococcus furiosus

Frontiers in Microbiology, 2023
The regulation of archaellation, the formation of archaeal-specific cell appendages called archaella, is crucial for the motility, adhesion, and survival of archaeal organisms.
