== Function ==
[https://www.uniprot.org/uniprot/CLPP_STAA8 CLPP_STAA8] Cleaves peptides in various proteins in a process that requires ATP hydrolysis. Has a chymotrypsin-like activity. Plays a major role in the degradation of misfolded proteins (By similarity).

== Publication Abstract from PubMed ==
Acyldepsipeptides are a unique class of antibiotics that act via allosterically dysregulated activation of the bacterial caseinolytic protease (ClpP). The ability of ClpP activators to kill nongrowing bacteria represents a new opportunity to combat deep-seated biofilm infections. However, the acyldepsipeptide scaffold is subject to rapid metabolism. Herein, we explore alteration of the potentially metabolically reactive alpha,beta unsaturated acyl chain. Through targeted synthesis, a new class of phenyl urea substituted depsipeptide ClpP activators with improved metabolic stability is described. The ureadepsipeptides are potent activators of Staphylococcus aureus ClpP and show activity against Gram-positive bacteria, including S. aureus biofilms. These studies demonstrate that a phenyl urea motif can successfully mimic the double bond, maintaining potency equivalent to acyldepsipeptides but with decreased metabolic liability. Although removal of the double bond from acyldepsipeptides generally has a significant negative impact on potency, structural studies revealed that the phenyl ureadepsipeptides can retain potency through the formation of a third hydrogen bond between the urea and the key Tyr63 residue in the ClpP activation domain. Ureadepsipeptides represent a new class of ClpP activators with improved drug-like properties, potent antibacterial activity, and the tractability to be further optimized.
