A research group examining how bacteria cope with stress, for example how the receptor meolecule CadC monitors the acidity in the environment and alerts the cell to take countermeasures to protect itself, led to some answers about protein synthesis, the core biosynthetic process that makes all metabolism possible.

They found that, in the absence of  Translation Elongation Factor P (EF-P, for short), the cell doesn’t make enough CadC to carry out its job effectively.
