Clp may be responsible for a fairly general and central housekeeping function rather than for the degradation of specific substrates. Publication Abstract from PubMed Acyldepsipeptides (ADEPs) are potential antibiotics that dysregulate the activity of the highly conserved tetradecameric bacterial ClpP protease, leading to bacterial cell death. Here, we identified ADEP analogs that are potent dysregulators of the human mitochondrial ClpP (HsClpP). These ADEPs interact tightly with HsClpP, causing the protease to non-specifically degrade model substrates. Dysregulation of HsClpP activity by ADEP was found to induce cytotoxic effects via activation of the intrinsic, caspase-dependent apoptosis. ADEP-HsClpP co-crystal structure was solved for one of the analogs revealing a highly complementary binding interface formed by two HsClpP neighboring subunits but, unexpectedly, with HsClpP in the compact conformation. Given that HsClpP is highly expressed in multiple cancers and has important roles in cell metastasis, our findings suggest a therapeutic potential for ADEPs in cancer treatment.
