Ancestral Reconstructions Decipher Major Adaptations of Ammonia-Oxidizing Archaea upon Radiation into Moderate Terrestrial and Marine Environments

mBio, 2020
Unlike all other archaeal lineages, ammonia-oxidizing archaea (AOA) of the phylum Thaumarchaeota are widespread and abundant in all moderate and oxic environments on Earth. The evolutionary adaptations that led to such unprecedented ecological success of

Gut microbiota alterations in patients with non‐small‐cell lung cancer undergoing chemoradiotherapy

Molecular Oncology, EarlyView.
We investigated the impact of concurrent chemoradiotherapy (CRT) on the gut microbiota in patients with locally advanced non‐small‐cell lung cancer. Overall gut microbiota composition remained largely stable throughout CRT while antibiotic exposure may influence microbial diversity.

A Well-Conserved Archaeal B-Family Polymerase Functions as an Extender in Translesion Synthesis

mBio, 2022
B-family DNA polymerases (PolBs) of different groups are widespread in Archaea, and different PolBs often coexist in the same organism. Many of these PolB enzymes remain to be investigated.

Editorial: New insights into the genetic mechanisms of thermophilic archaea [PDF]

, 2023
Archaea were recognized as the third domain of cellular life, besides Bacteria and Eukarya, by Carl Woese and George Fox in 1977 (Woese and Fox, 1977).

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

FEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Cran1, member of a new class of OLD family ATPases, functions in cell cycle progression in an archaeon

EMBO Reports
Overcoming lysogenization defect (OLD) proteins are diverse ATPase-nucleases functioning in antiphage defense in bacteria. However, the role of these proteins in archaea is currently unknown.

Analysis of Cell–Cell Bridges in Haloferax volcanii Using Electron Cryo-Tomography Reveal a Continuous Cytoplasm and S-Layer

Frontiers in Microbiology, 2021
Halophilic archaea have been proposed to exchange DNA and proteins using a fusion-based mating mechanism. Scanning electron microscopy previously suggested that mating involves an intermediate state, where cells are connected by an intercellular bridge ...

Translation Regulation: The Archaea-Eukaryal Connection

, 2017
Translation, as an essential cellular process, is very well conserved through evolution. Nonetheless, the translational apparatus, namely the ribosomes and the accessory protein factors that assist all the steps of translation, have incurred a certain ...

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

FEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.
