Nutrient smuggling: Commensal gut bacteria‐derived extracellular vesicles scavenge vitamin B12 and related cobamides for microbe and host acquisition

1 Oct 2022

Abstract excerpt

Abstract The processes by which bacteria proactively scavenge essential nutrients in crowded environments such as the gastrointestinal tract are not fully understood. In this context, we observed that bacterial extracellular vesicles (BEVs) produced by the human commensal gut microbe Bacteroides thetaiotaomicron contain multiple high‐affinity vitamin B 12 binding proteins suggesting that the vesicles play a role...
