  eLife assessment

  Salmonella invades and survives in host cells via SPI-1 and SPI-2 type III secretion system mechanisms, with the SPI-2 system allowing for intracellular survival in Salmonella-containing vacuoles, which have a low-pH environment. Transcription of SPI-2 genes at low pH is activated by the DNA-binding SsrB protein, which sits at the top of the SPI-2 regulatory hierarchy. This study provides important insights as to how SsrB is allosterically affected by pH resulting in acid-dependent DNA binding. However, there are concerns about some experiments, and the evidence presented is not fully conclusive.
