Altered Gut Archaea Composition and Interaction with Bacteria are Associated with Colorectal Cancer. [PDF]

Gastroenterology, 2020
BACKGROUND & AIMS Changes in the intestinal microbiota have been associated with development and progression of colorectal cancer (CRC). Archaea are stable components of the microbiota, but little is known about their composition or contribution to ...

Complex archaea that bridge the gap between prokaryotes and eukaryotes

Nature, 2015
The origin of the eukaryotic cell remains one of the most contentious puzzles in modern biology. Recent studies have provided support for the emergence of the eukaryotic host cell from within the archaeal domain of life, but the identity and nature of ...

Characterization of the ATPase FlaI of the motor complex of the Pyrococcus furiosus archaellum and its interactions between the ATP-binding protein FlaH [PDF]

PeerJ, 2018
The archaellum, the rotating motility structure of archaea, is best studied in the crenarchaeon Sulfolobus acidocaldarius. To better understand how assembly and rotation of this structure is driven, two ATP-binding proteins, FlaI and FlaH of the motor ...

The FHA domain protein ArnA functions as a global DNA damage response repressor in the hyperthermophilic archaeon Saccharolobus islandicus

mBio, 2023
Forkhead-associated (FHA) domain proteins specifically recognize phosphorylated threonine via the FHA domain and are involved in signal transduction in various processes especially DNA damage response (DDR) and cell cycle regulation in eukaryotes ...

Recoding in Archaea [PDF]

Molecular Microbiology, 2004
SummaryStandard decoding of the genetic information into polypeptides is performed by one of the most sophisticated cell machineries, the translating ribosome, which, by following the genetic code, ensures the correspondence between the mature mRNA and the protein sequence.

Analysis of biomass productivity and physiology of Nitrososphaera viennensis grown in continuous culture

Frontiers in Microbiology, 2023
Microbial ammonia oxidation is the first and usually rate limiting step in nitrification and is therefore an important step in the global nitrogen cycle. Ammonia-oxidizing archaea (AOA) play an important role in nitrification.

Biomethanation of Carbon Monoxide by Hyperthermophilic Artificial Archaeal Co-Cultures

Fermentation, 2021
Climate neutral and sustainable energy sources will play a key role in future energy production. Biomethanation by gas to gas conversion of flue gases is one option with regard to renewable energy production.

Genome-resolved metagenomics reveals site-specific diversity of episymbiotic CPR bacteria and DPANN archaea in groundwater ecosystems

Nature Microbiology, 2021
Candidate phyla radiation (CPR) bacteria and DPANN archaea are unisolated, small-celled symbionts that are often detected in groundwater. The effects of groundwater geochemistry on the abundance, distribution, taxonomic diversity and host association of ...

Archaea [PDF]

, 2021
In agreement with their close relationship to eukaryotes, Archaea encode informational processing machineries that closely resemble those of eukaryotic representatives. The composition of archaeal cell membranes differs fundamentally from those of Bacteria and eukaryotes.

Archaeal GPN-loop GTPases involve a lock-switch-rock mechanism for GTP hydrolysis

mBio, 2023
Three GPN-loop GTPases, GPN1–GPN3, are central to the maturation and trafficking of eukaryotic RNA polymerase II. This GTPase family is widely represented in archaea but typically occurs as single paralogs.
