Abstract

ATP-dependent proteases are found in nearly all living organisms and are known to play important roles in protein quality control, including protein degradation and protein refolding. ATP-dependent proteases have been well characterized in Escherichia coli. However, in the opportunistic human pathogen Pseudomonas aeruginosa, the role of these proteases is only starting to be understood. This review will discuss the most recent research regarding the role of ATP-dependent proteases, particularly Lon and ClpP, in P. aeruginosa. These studies have revealed that despite the fact that they are not traditional regulators, these proteases are involved in regulating a multitude of processes, including antibiotic resistance and virulence, implicating a broad array of functions that these intracellular proteases have in Pseudomonas. These results are also relevant in the context of drug therapy, since ClpP and Lon are good candidates to become novel therapeutic targets to combat Pseudomonas infections.
