A pathogen-specific isotope tracing approach reveals metabolic activities and fluxes of intracellular Salmonella

How do intracellular pathogenic bacteria scavenge essential nutrients from the host? Difficulties in distinguishing between bacterial and host metabolites have made this challenging to address, but this study shows that 13C-mannitol allows direct tracking of the metabolism of Salmonella when growing inside host cells, revealing the food sources and metabolic pathways that intracellullar pathogens use.

New globally distributed bacterial phyla within the FCB superphylum https://www.nature.com/articles/s41467-022-34388-1

"The volume of #proteins found in these phyla that have no similarity to any known sequence is exciting. It is fascinating that these previously overlooked #microbes have different #MetabolicPathways which could support their worldwide distribution in different habitats"

Newly discovered bacteria and their proteins could advance our understanding of global nutrients

The power of metagenomics strikes again. Marine microbiologists discovered five new bacteria phyla (four never described and one poorly described) from the ocean floor that contain an unusually large number of novel protein families. An international group of researchers led by...

Meteorites and simple metals as catalysts for #metabolicpathways at the origin of life @unistra @angew_chem https://onlinelibrary.wiley.com/doi/10.1002/anie.202212932 https://phys.org/news/2022-10-meteorites-simple-metals-catalysts-metabolic.html

Meteorites and simple metals as catalysts for metabolic pathways at the origin of life

Researchers from the University of Strasbourg have demonstrated that hydrogen gas and simple metals or meteorites cause parts of the reverse Krebs cycle to occur without enzymes. Some version of this metabolic pathway is thought to date back to life's origin. The results of this study support the hypothesis that naturally occurring metals acted as catalysts for the first protometabolic reactions.
