The paper identifies tandem repeats in methanogenic archaea and their viruses, showing they contribute to genomic diversity and adaptation potential.

The paper identifies a symbiont-derived biosurfactant that links host neuroimmune control of intestinal peristalsis with bacterial susceptibility to expulsion.

The paper presents cryo-EM structures of the Mtr complex from Methanosarcina mazei, revealing a novel [Fe8S9C] cluster near the catalytic site and suggesting a link between methyl transfer and Na+ translocation.

This study evaluates 42 new Bacteroidota strains for probiotic potential, finding they inhibit biofilm formation and exhibit quorum quenching and bile salt hydrolase activity.

The paper identifies MttS and MttQ as small proteins that regulate TMA transport via interaction with the MttP transporter in Methanosarcina mazei, revealing their role in TMA specificity and ecological adaptation.

This study identifies and characterizes sRNA/asRNA pairs in Methanosarcina mazei, showing their role in stress adaptation through encoded small proteins and antisense regulation.

The paper presents a cryo-EM structure of the Mtr complex from Methanosarcina mazei and identifies a small ORF protein, MtrI, involved in oxygen stress response.

The paper characterizes the small protein MtrR in Methanosarcina mazei, showing it modulates Mtr activity in response to hydrogen, affecting growth under varying H2 conditions.

This study shows that 2-oxoglutarate induces dodecamer assembly of Methanosarcina mazei glutamine synthetase, enhancing its activity through a cooperative mechanism.

The paper presents a chromosome-level genome of Mnemiopsis leidyi, revealing unique immune gene domains and their expression in response to pathogen exposure.

This study isolates and characterizes novel Methanobrevibacter strains from human fecal samples, expanding the cultivated archaeome and linking them to gastrointestinal health.

This study identifies a small protein, sP36, that regulates ammonium transport in Methanosarcina mazei by interacting with AmtB1 and GlnK1, revealing an ancient archaeal mechanism distinct from bacterial regulation.

The paper analyzes 1,167 archaeal genomes from the human gut to reveal novel species, genomic adaptations, and correlations with socio-demographic factors.

This study isolates and evaluates bacteria from two marine invertebrates, identifying quorum quenching activity in many isolates that may influence microbial community dynamics.
