A human gut bacterium antagonizes neighboring bacteria by altering their protein-folding ability
Antagonism shapes microbiomes. Lim et al. identify a mechanism used by human gut commensals
to antagonize related bacteria. The secreted effector Bte1 alters the protein-folding
machinery of targeted ...
