Antibacterial peptide CyclomarinA creates toxicity by deregulating the Mycobacterium tuberculosis ClpC1–ClpP1P2 protease

Abstract excerpt

The ring-forming AAA+ hexamer ClpC1 associates with the peptidase ClpP1P2 to form a central ATP-driven protease in Mycobacterium tuberculosis (Mtb). ClpC1 is essential for Mtb viability and has been identified as the target of antibacterial peptides like CyclomarinA (CymA) that exhibit strong toxicity toward Mtb. The mechanistic actions of these drugs are poorly understood. Here, we dissected how ClpC1 activity...
