Abstract：
:General and regulated proteolysis in bacteria is crucial for cellular homeostasis and relies on high substrate specificity of the executing AAA+ proteases. Here we summarize the various strategies that tightly control substrate degradation from both sides: the generation of accessible degrons and their specific recognition by AAA+ proteases and cognate adaptor proteins.
