UbiB proteins mediate an ATP‐dependent decarboxylation step in bacterial ubiquinone biosynthesis

The FEBS Journal, EarlyView.
UbiB proteins are atypical protein kinase‐like enzymes essential for ubiquinone biosynthesis. Here, we demonstrate that bacterial UbiB proteins catalyze the O2‐dependent decarboxylation of ubiquinone precursors, a process linked to their ATPase activity.

Investigating the evolution of phototrophy in Pseudomonadota

International audiencePhototrophy is an ancient bacterial metabolism that likely originated over 3 billion years ago, prior to the rise of atmospheric oxygen provoked by oxygenic photosynthesis of Cyanobacteriia.

Shotgun Metagenomic Analysis Reveals Taxonomic and Functional Transitions in the Salivary Microbiome During Periodontal Disease Progression

Journal of Clinical Periodontology, EarlyView.
ABSTRACT Aim To characterise multi‐kingdom salivary microbiome profiles across clinically defined periodontal states and identify stage‐specific taxonomic and functional alterations using shotgun metagenomic sequencing. Materials and Methods In this cross‐sectional study, 204 adults (mean age 40.3 ± 7.6 years) from the SECRETO study (NCT01934725 ...

Airborne microorganisms in muddy rain: microbe-mineral interactions and their ecosystem impact

Frontiers in Microbiology
The Sahara Desert and the Sahel region in North Africa contribute approximately 50–70% of global atmospheric dust emissions. Microorganisms can attach to dust particles and be dispersed into exogenous environments, being subsequently deposited by ...

Periodontal Medicine Rewired: Mechanisms Linking Periodontitis to Systemic Diseases

Journal of Periodontal Research, EarlyView.
This review reorganizes decades of research in periodontal medicine into a multi‐dimensional framework, illustrating how periodontitis influences systemic health through at least seven interconnected mechanisms. ABSTRACT Periodontitis is now recognized not merely as a localized oral condition but as a systemic disease linked to over 70 communicable and

Bacterial composition of Polygenis (Polygenis) bohlsi bohlsi (Wagner, 1901) (Siphonaptera: Rhopalopsyllidae) associated with Thrichomys fosteri (Rodentia: Echimyidae) in the Brazilian Pantanal wetland

Medical and Veterinary Entomology, EarlyView.
This study characterizes the bacteriome of Polygenis (Polygenis) bohlsi bohlsi fleas collected from free‐living Thrichomys fosteri in the Pantanal region of Brazil. The bacterial microbiota associated with male fleas exhibited greater phylogenetic diversity, and the overall community structure differed between the flea sexes.

Microbial diversity of high-elevated fumarole fields, low-biomass communities on the boundary between ice and fire

Scientific Reports
Fumarole fields on active volcanoes are habitats that host unique microbial ecosystems. However, DNA extraction from them for further analysis is rather challenging.

Reciprocal transport of carbon and nitrogen between plants and the hyphosphere microbiome in a temperate grassland

New Phytologist, EarlyView.
Overview of the experimental design and 13CO2 pulse‐labeling approach in the field. Summary Despite its relevance for plant nutrient acquisition, the role of the hyphosphere in structuring fungal–bacterial networks and mediating carbon–nitrogen (C–N) exchange under field conditions remains unclear.
