Groundwater Microbial Diversity Associated With Icelandic Basaltic Subsurface Environments
Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.Overview of microbial diversity and environmental drivers in Icelandic deep basaltic aquifers. Using 16S rRNA gene metabarcoding across 22 geothermal wells spanning broad temperature, pH, and bedrock‐age gradients, the study reveals distinct bacterial and archaeal community structures shaped by temperature, pH, and host‐rock reactivity.

The Lrs14‐Like AbfR1 Homolog From Metallosphaera sedula Is a Nucleoid‐Organizing Protein
MicrobiologyOpen, Volume 14, Issue 5, October 2025.Nucleoid organization in Crenarchaeota involves diverse small DNA‐binding proteins. The Lrs14‐type protein AbfR1 from Metallosphaera sedula binds nonsequence specifically across the genome and induces DNA condensation. These findings suggest a structural role for AbfR1Ms in chromatin architecture, functionally resembling bacterial nucleoid‐associated ...

Crystal structure of the S. solfataricus archaeal exosome reveals conformational flexibility in the RNA-binding ring. [PDF]
PLoS ONE, 2010 The exosome complex is an essential RNA 3'-end processing and degradation machinery. In archaeal organisms, the exosome consists of a catalytic ring and an RNA-binding ring, both of which were previously reported to assume three-fold symmetry.Here we ...

Phylogenetic differences in content and intensity of periodic proteins [PDF]
, 2005 Many proteins exhibit sequence periodicity, often correlated with a visible structural periodicity. The statistical significance of such periodicity can be assessed by means of a chi-square-based test, with significance thresholds being calculated from ...

Molecular Ecology Resources, Volume 25, Issue 7, October 2025.ABSTRACT Linking meta‐omics and biogeochemistry approaches in soils has remained challenging. This study evaluates the use of an internal RNA extraction standard and its potential for making quantitative estimates of a given microbial community size (biomass) in soil metatranscriptomics. We evaluate commonly used laboratory protocols for RNA processing,

Activation of SsoPK4, an Archaeal eIF2α Kinase Homolog, by Oxidized CoA
Proteomes, 2015 The eukaryotic protein kinase (ePK) paradigm provides integral components for signal transduction cascades throughout nature. However, while so-called typical ePKs permeate the Eucarya and Bacteria, atypical ePKs dominate the kinomes of the Archaea ...
