"Biogenesis of DNA-carrying extracellular vesicles by the dominant human gut methanogenic archaeon"

In this study, we characterized the extracellular vesicles (EVs) produced by the human gut-associated archaeon Methanobrevibacter smithii. Cryo-electron tomography revealed that the EVs form by budding from the membrane and are released through the peptidoglycan layer. These EVs are enriched in histones, DNA repair proteins, and extrachromosomal circular DNA (eccDNA), which is linked to methanogenesis, suggesting a potential role in regulating methane production in the human gut.
