Structure of ClpP from Bacillus subtilis in monoclinic crystal formStructure of ClpP from Bacillus subtilis in monoclinic crystal form
Structural highlights
Function[CLPP_BACSU] 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). ClpXP is involved in the complete degradation of the Site-2 clipped anti-sigma-W factor RsiW. This results in the release of SigW and the transcription activation of the genes under the control of the sigma-W factor.[1] Evolutionary Conservation![]() Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedClp-family proteins are prototypes for studying the mechanism of ATP-dependent proteases because the proteolytic activity of the ClpP core is tightly regulated by activating Clp-ATPases. Nonetheless, the proteolytic activation mechanism has remained elusive because of the lack of a complex structure. Acyldepsipeptides (ADEPs), a recently discovered class of antibiotics, activate and disregulate ClpP. Here we have elucidated the structural changes underlying the ClpP activation process by ADEPs. We present the structures of Bacillus subtilis ClpP alone and in complex with ADEP1 and ADEP2. The structures show the closed-to-open-gate transition of the ClpP N-terminal segments upon activation as well as conformational changes restricted to the upper portion of ClpP. The direction of the conformational movement and the hydrophobic clustering that stabilizes the closed structure are markedly different from those of other ATP-dependent proteases, providing unprecedented insights into the activation of ClpP. Structures of ClpP in complex with acyldepsipeptide antibiotics reveal its activation mechanism.,Lee BG, Park EY, Lee KE, Jeon H, Sung KH, Paulsen H, Rubsamen-Schaeff H, Brotz-Oesterhelt H, Song HK Nat Struct Mol Biol. 2010 Apr;17(4):471-8.
