  • Polyproline motifs induce ribosome stalling during translation. Here, Ignatov et al. identify RNA-binding proteins in the pathogenic bacterium Streptococcus pyogenes, and show that one of these proteins, YebC, acts as a translation factor enhancing translation of proteins with polyproline motifs.

  • The bactericidal activity of several antibiotics partially relies on production of reactive oxygen species (ROS), which requires the Fenton reaction. Here, the authors show that membrane depolarization also leads to ROS production, but this occurs via other mechanisms that do not require the Fenton reaction.

  • The mechanisms of action of the antibacterial metalloid tellurite are unclear. Here, the authors show that tellurite induces an accumulation of hydroxyl radical and intermediates of heme biosynthesis inE. coli, and that the heme precursor 5-aminolevulinic acid potentiates tellurite toxicity.
