ATP-dependent Clp protease (ClpP) is an attractive new target for the development of anti-infective agents. The ClpP protease consists of two heptameric rings that enclose a large chamber containing 14 proteolytic active sites. Recent studies indicate that ClpP likely undergoes conformational switching between an extended and degraded active state required for substrate proteolysis and a compacted and catalytically inactive state allowing product release. Here, we present the wild-type ClpP structures in two distinct states from Staphylococcus aureus. One structure is very similar to those solved ClpP structures in the extended states. The other is strikingly different from both the extended and the compacted state as observed in ClpP from other species; the handle domain of this structure kinks to take on a compressed conformation. Structural analysis and molecular dynamic simulations show that the handle domain predominantly controls the way in which degradation products exit the chamber through dynamic conformational switching from the extended state to the compressed state. Given the highly conserved sequences among ClpP from different species, this compressed conformation is unexpected and novel, which is potentially valuable for understanding the enzymatic dynamics and the acting mechanisms of ClpP.
