== Publication Abstract from PubMed ==
We have determined the crystal structure of the proteolytic component of the caseinolytic Clp protease (ClpP) from E. coli at 2.3 A resolution using an ab initio phasing procedure that exploits the internal 14-fold symmetry of the oligomer. The structure of a ClpP monomer has a distinct fold that defines a fifth structural family of serine proteases but a conserved catalytic apparatus. The active protease resembles a hollow, solid-walled cylinder composed of two 7-fold symmetric rings stacked back-to-back. Its 14 proteolytic active sites are located within a central, roughly spherical chamber approximately 51 A in diameter. Access to the proteolytic chamber is controlled by two axial pores, each having a minimum diameter of approximately 10 A. From the structural features of ClpP, we suggest a model for its action in degrading proteins.
The structure of ClpP at 2.3 A resolution suggests a model for ATP-dependent proteolysis.,Wang J, Hartling JA, Flanagan JM Cell. 1997 Nov 14;91(4):447-56. PMID:9390554<ref>PMID:9390554</ref>

THE STRUCTURE OF CLPP AT 2.3 ANGSTROM RESOLUTION SUGGESTS A MODEL FOR ATP-DEPENDENT PROTEOLYSISTHE STRUCTURE OF CLPP AT 2.3 ANGSTROM RESOLUTION SUGGESTS A MODEL FOR ATP-DEPENDENT PROTEOLYSIS

Structural highlights

1tyf is a 14 chain structure with sequence from Escherichia coli. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 2.3Å
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

CLPP_ECOLI 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. May play the role of a master protease which is attracted to different substrates by different specificity factors such as ClpA or ClpX.

Evolutionary Conservation
