Comprehensive Sampling Across Seasons and Habitats Revealed the Composition and Functional Attributes of Gut Microbiota Enterotypes in Subterranean Rodents

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
The gut microbiota of Gansu zokor is classified into two enterotypes, which exhibit distinct seasonal and habitat distributions, microbial diversity, and community compositions dominated by different Bacillota‐to‐Bacteroidota ratios. These enterotypes correlate with host body size and are characterized by unique probiotic and pathogenic biomarkers ...

Genetic basis for nitrate resistance in Desulfovibrio strains

open access: yesFrontiers in Microbiology, 2014
Nitrate is an inhibitor of sulfate-reducing bacteria (SRB). In petroleum production sites, amendments of nitrate and nitrite are used to prevent SRB production of sulfide that causes souring of oil wells.

Multiple single-cell genomes provide insight into functions of uncultured Deltaproteobacteria in the human oral cavity.

open access: yesPLoS ONE, 2013
Despite a long history of investigation, many bacteria associated with the human oral cavity have yet to be cultured. Studies that correlate the presence or abundance of uncultured species with oral health or disease highlight the importance of these ...

Natural Products as the Modulators of Gut Microbiota: A Pool for the Development of New Treatment Against Obesity?

open access: yesFood Frontiers, Volume 7, Issue 3, May 2026.
Natural compounds regulate gut microbiota by improving microbial balance and increasing probiotics, which boost short‐chain fatty acid production to alleviate insulin resistance and inflammation. Additionally, they stimulate appetite‐suppressing hormones through bile acid signaling, while inhibiting pathogenic bacteria to repair intestinal barrier ...

Linking NrfD/PsrC‐like architecture to energy conservation: Functional residues in the quinone reactive QrcABCD complex of sulfate‐reducing bacteria

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract The QrcABCD quinone reductase complex is an electrogenic complex present in sulfate‐reducing bacteria of the Desulfobacterota phylum. It operates as a cytochrome c3:menaquinone oxidoreductase involved in electron transfer from periplasmic hydrogen or formate oxidation to the menaquinone (MK) pool.

Structural Insights Into CO2 Transport Pathways in a W‐Formate Dehydrogenase: Structural Basis for CO2 Reduction

open access: yesAngewandte Chemie, Volume 138, Issue 16, 13 April 2026.
Integrated structural analysis of N. vulgaris formate dehydrogenase AB, an enzyme with applications in climate change mitigation, is reported. The substrate/product diffusion pathways were fully mapped, and a retention site was identified that transiently holds substrates and has a key role in CO2‐reducing activity.

Nuclear Resonance Vibrational Spectroscopy of Iron Sulfur Proteins

open access: yes, 2012
Nuclear inelastic scattering in conjunction with density functional theory (DFT) calculations has been applied for the identification of vibrational modes of the high-spin ferric and the high-spin ferrous iron-sulfur center of a rubredoxin-type protein ...

Putative Analogs of Pyrite Suns Forming in Proglacial Alaska Mudflats

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Disc‐shaped pyrite suns of the Pennsylvanian age Anna Shale are thought to have formed where pressure restricted pyrite crystal growth to a flattened disc shape during diagenesis at the Anna Shale and the underlying Herrin coal boundary.

Structures of variants of Escherichia coli flavodiiron‐type nitric oxide reductase reveal changes in the di‐iron site

open access: yesActa Crystallographica Section D, Volume 82, Issue 5, Page 457-470, May 2026.
Flavodiiron proteins (FDPs) are di‐iron enzymes that reduce NO and/or O2 with distinct substrate selectivity. We have produced E. coli FDP variants targeting second coordination‐sphere residues and determined their structures. Although the kinetics remained unchanged, the E.
