We observed that the second messenger (p)ppGpp, known to be synthesized by the ribosome-associated Rel synthetase upon nutrient starvation during the stringent response, is also intricately involved in the stress response of B. subtilis cells and can act as a pleiotropic regulator during the adaptation to heat stress. (p)ppGpp can slow down and modulate translation and is, together with the transcriptional stress regulator Spx, partially involved in the transcriptional down-regulation of the translation machinery. The stress-induced elevation of cellular (p)ppGpp levels confers increased stress tolerance and facilitates an improved protein homeostasis by modulating translation and reducing the load on the protein quality control system.
