Changes in microbial (Bacteria and Archaea) plankton community structure after artificial dispersal in grazer-free microcosms [PDF]

open access: yes, 2017
Microbes are considered to have a global distribution due to their high dispersal capabilities. However, our knowledge of the way geographically distant microbial communities assemble after dispersal in a new environment is limited.

Metagenomic analysis of bacterial and archaeal assemblages in the soil-mousse surrounding a geothermal spring

open access: yesGenomics Data, 2015
The soil-mousse surrounding a geothermal spring was analyzed for bacterial and archaeal diversity using 16S rRNA gene amplicon metagenomic sequencing which revealed the presence of 18 bacterial phyla distributed across 109 families and 219 genera ...

Aerobic Lineage of the Oxidative Stress Response Protein Rubrerythrin Emerged in an Ancient Microaerobic, (Hyper)Thermophilic Environment [PDF]

open access: yes, 2016
Indexación: Web of Science; Scopus.Rubrerythrins (RBRs) are non-heme di-iron proteins belonging to the ferritin-like superfamily. They are involved in oxidative stress defense as peroxide scavengers in a wide range of organisms. The vast majority of RBRs,

Snapshots of Motion: A Novel Structural Intermediate Reveals Conserved Dynamics in Archaeal DNA Ligases

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 6, Page 1245-1258, June 2026.
ABSTRACT We present the first x‐ray crystallographic structural evidence of an archaeal DNA ligase showing the AMP covalent adduct together with further cofactor hydrolysis, capturing a transient intermediary in the first step of the ligation reaction, triggered by the pyrophosphate hydrolysis.

Crystal structures of PCNA1 and PCNA2 from Aeropyrum pernix: implications for a distorted heterotrimeric sliding clamp

open access: yesActa Crystallographica Section F, Volume 82, Issue 6, Page 216-221, June 2026.
Crystal structures of A. pernix PCNA1 (1.60 Å resolution) and PCNA2 (2.17 Å resolution) are reported. High‐resolution analysis reveals a rare nonproline cis‐peptide bond in PCNA1 that may cause steric hindrance at the subunit interface, suggesting a distorted or symmetry‐broken heterotrimeric PCNA ring.Aeropyrum pernix is a hyperthermophilic archaeon ...
