Nucleases and Their Inhibitors: Exploring Biological Roles, Industrial Applications, and Challenges in Heterologous Expression

open access: yesBiotechnology Journal, Volume 21, Issue 9, September 2026.
Graphical Abstract and Lay Summary Intracellular nucleases, depicted as blue circles in a nucleosome, hydrolyze phosphodiester bonds, repair damaged DNA using DNA base excision repair (BER), mismatch repair (MMR), and homologous recombination (HR), and are involved in DNA replication.

Pangenome of Streptomyces sampsonii and Relatives Highlights Horizontal Gene Transfer and Secondary Metabolism in Environmental Adaptation and Ecological Significance

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
This study presents a chromosome‐level genome assembly of Streptomyces sampsonii and a pangenome analysis of 95 strains, revealing a highly expansive “open” pangenome. Our results highlight that horizontal gene transfer (HGT) and accessory gene variations drive the evolution of secondary metabolism and environmental adaptation.

PCR biases distort bacterial and archaeal community structure in pyrosequencing datasets [PDF]

open access: yes, 2012
As 16S rRNA gene targeted massively parallel sequencing has become a common tool for microbial diversity investigations, numerous advances have been made to minimize the influence of sequencing and chimeric PCR artifacts through rigorous quality control ...

Reconstructed ancestral Myo-inositol-3-phosphate synthases indicate that ancestors of the Thermococcales and Thermotoga species were more thermophilic than their descendants.

open access: yesPLoS ONE, 2013
The bacterial genomes of Thermotoga species show evidence of significant interdomain horizontal gene transfer from the Archaea. Members of this genus acquired many genes from the Thermococcales, which grow at higher temperatures than Thermotoga species ...

Antarctic soil microbiomes encode structurally conserved and phylogenetically diverse beta‐lactamases

open access: yesiMetaOmics, Volume 3, Issue 3, September 2026.
An integrative metagenomic framework combining sequence, structural, and functional inference reveals a phylogenetically diverse and structurally conserved repertoire of putative beta‐lactamases across Antarctic soil microbiomes, with predominance of class A and subclass B3 enzymes and limited but detectable associations with mobile genetic elements ...

Characterization of TPP-binding proteins in Methanococci archaeal species [PDF]

open access: yesBioinformation, 2016
Acetolactate synthase (ALS) is a highly conserved protein family responsible for producing branched chain amino acids. In Methanocaldococcus jannaschii, two ALS proteins, MJ0277 and MJ0663 exist though variations in features between them are noted. Researchers are quick to examine MJ0277 homologs due to their increased function and close relationship ...

Phylogenetic tree archaeal MAGs 16 ribosomal proteins

open access: yes, 2019
Phylogenetic tree of all archaeal MAGs analyzed in this study based on 16 ribosomal proteins. References included in the tree were obtained from Hug et al. (2016, Nature Microbiology) and Vavourakis et al. (2018, Microbiome)

Viruses in the sediments around the trenches harbor diverse survival mechanisms

open access: yesiMetaOmics, Volume 3, Issue 3, September 2026.
Deep‐sea trenches are the deepest and most isolated environments in the global ocean but the diversity and adaptation of the viral communities remain poorly characterized. In this study, 5563 viral operational taxonomic units (vOTUs) were identified from sediments of the Yap Trench and Western Caroline Basin.

Structures of Saccharolobus solfataricus initiation complexes with leaderless mRNAs highlight archaeal features and eukaryotic proximity

open access: yesNature Communications
The archaeal ribosome is of the eukaryotic type. TACK and Asgard superphyla, the closest relatives of eukaryotes, have ribosomes containing eukaryotic ribosomal proteins not found in other archaea, eS25, eS26 and eS30.
