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.

Habitat transition in the evolution of bacteria and archaea [PDF]
arXiv, 2023 Related groups of microbes are widely distributed across Earth's habitats, implying numerous dispersal and adaptation events over evolutionary time. However, to date, relatively little is known about the characteristics and mechanisms of these habitat transitions, particularly for populations that reside in animal microbiomes.

The Space Experiment of the Exo-ecosystem [PDF]
arXiv, 2023 The experiment of exo-ecosystem and the exploration of extraterrestrial habitability aims to explore the adaptation of terrestrial life in space conditions for the manned space program and the future interstellar migration, which shows great scientific significance and public interests. By our knowledge the early life on Earth, archaea and extremophile

Nature Communications, 2019 The S-layer is a proteinaceous envelope often found in bacterial and archaeal cells. Here, the authors use CRISPR-based technology to silence slaB, encoding the S-layer membrane anchor, to show that an intact S-layer is important for cell division and ...

Enzymatic Switching Between Archaeal DNA Polymerases Facilitates Abasic Site Bypass
Frontiers in Microbiology, 2021 Abasic sites are among the most abundant DNA lesions encountered by cells. Their replication requires actions of specialized DNA polymerases. Herein, two archaeal specialized DNA polymerases were examined for their capability to perform translesion DNA ...

Ecology, Volume 103, Issue 12, December 2022., 2022 Abstract Salinity fluctuations constitute a well‐known high stress factor strongly shaping global biological distributions and abundances. However, there is a knowledge gap regarding how increasing saline stress affects microbial biological interactions.

Structure and in situ organisation of the Pyrococcus furiosus archaellum machinery
eLife, 2017 The archaellum is the macromolecular machinery that Archaea use for propulsion or surface adhesion, enabling them to proliferate and invade new territories.

G-Quadruplexes in the Archaea Domain [PDF]
Biomolecules, 2020 The importance of unusual DNA structures in the regulation of basic cellular processes is an emerging field of research. Amongst local non-B DNA structures, G-quadruplexes (G4s) have gained in popularity during the last decade, and their presence and functional relevance at the DNA and RNA level has been demonstrated in a number of viral, bacterial ...

Functional activity of peptide ion channels in tethered bilayer lipid membranes: Review
Electrochemical Science Advances, Volume 2, Issue 6, December 2022., 2022 Abstract Ion transport across biomembranes plays a major role in living cells. This fundamental function is normally carried out by molecules with both a hydrophobic and a hydrophilic side (amphiphilic molecules), which aggregate within the membrane forming a hydrophilic pore (the ion channel) permitting the selective translocation of permeant ions ...
