Hydrogen Drives Part of the Reverse Krebs Cycle under Metal or Meteorite Catalysis
Angewandte Chemie International Edition, Volume 61, Issue 51, December 19, 2022., 2022 Hydrogen is a geological reducing agent that powers the metabolisms of modern organisms and potentially also powered the metabolism of the last universal common ancestor to all extant life. It is shown that catalytic amounts of transition metals or small amounts of powdered meteorites allow hydrogen to drive a key sequence of the reverse Krebs cycle ...

Grappling archaea: ultrastructural analyses of an uncultivated, cold-loving archaeon and its biofilm
Frontiers in Microbiology, 2014 Similarly to Bacteria, Archaea are microorganisms that interact with their surrounding environment in a versatile manner. To date, interactions based on cellular structure and surface appendages have mainly been documented using model systems of ...

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.

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.

Animal Research and One Health, EarlyView., 2023 In the present study, we created the weight gain models with Min and Yorkshire pigs and conducted the metagenomics and metabolomics of colon contents and transcriptomics of colon tissue. Further, we revealed the characteristics and functions of the colonic microbiota in Min and Yorkshire pigs and analyzed their interactions with the host. Overall, this

Anti-CRISPR-Based and CRISPR-Based Genome Editing of Sulfolobus islandicus Rod-Shaped Virus 2
Viruses, 2018 Genetic engineering of viruses has generally been challenging. This is also true for archaeal rod-shaped viruses, which carry linear double-stranded DNA genomes with hairpin ends.

Identity Elements of Archaeal tRNA [PDF]
DNA Research 12, 235--246 (2005), 2005 Features unique to a transfer-RNA are recognized by the corresponding tRNA-synthetase. Keeping this in view we isolate the discriminating features of all archaeal tRNA. These are our identity elements. Further, we investigate tRNA-characteristics that delineate the different orders of archaea.

Acid digestion and symbiont: Proton sharing at the origin of mitochondriogenesis?
BioEssays, Volume 45, Issue 1, January 2023., 2023 ADMit hypothesis for the origin of eukaryotes. A bacterial symbiont became associated with a protophagocytic host that captured prey with membrane processes. The symbiont cooperated to kill and digest the prey with reactive oxygen species and the acidification of the microenvironment.
