ID CLPP_RICPR Reviewed; 201 AA. AC Q9ZD29; DT 30-MAY-2000, integrated into UniProtKB/Swiss-Prot. DT 01-MAY-1999, sequence version 1. DT 27-MAR-2024, entry version 121. DE RecName: Full=ATP-dependent Clp protease proteolytic subunit {ECO:0000255|HAMAP-Rule:MF_00444}; DE EC=3.4.21.92 {ECO:0000255|HAMAP-Rule:MF_00444}; DE AltName: Full=Endopeptidase Clp {ECO:0000255|HAMAP-Rule:MF_00444}; GN Name=clpP {ECO:0000255|HAMAP-Rule:MF_00444}; OrderedLocusNames=RP520; OS Rickettsia prowazekii (strain Madrid E).

OX NCBI_TaxID=272947; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=Madrid E; RX PubMed=9823893; DOI=10.1038/24094; RA Andersson S.G.E., Zomorodipour A., Andersson J.O., Sicheritz-Ponten T., RA Alsmark U.C.M., Podowski R.M., Naeslund A.K., Eriksson A.-S., Winkler H.H., RA Kurland C.G.; RT "The genome sequence of Rickettsia prowazekii and the origin of RT mitochondria."; RL Nature 396:133-140(1998). CC -!- FUNCTION: Cleaves peptides in various proteins in a process that CC requires ATP hydrolysis. Has a chymotrypsin-like activity. Plays a CC major role in the degradation of misfolded proteins. CC {ECO:0000255|HAMAP-Rule:MF_00444}. CC -!- CATALYTIC ACTIVITY: CC Reaction=Hydrolysis of proteins to small peptides in the presence of CC ATP and magnesium. alpha-casein is the usual test substrate. In the CC absence of ATP, only oligopeptides shorter than five residues are CC hydrolyzed (such as succinyl-Leu-Tyr-|-NHMec, and Leu-Tyr-Leu-|-Tyr- CC Trp, in which cleavage of the -Tyr-|-Leu- and -Tyr-|-Trp bonds also CC occurs).; EC=3.4.21.92; Evidence={ECO:0000255|HAMAP-Rule:MF_00444}; CC -!- SUBUNIT: Fourteen ClpP subunits assemble into 2 heptameric rings which CC stack back to back to give a disk-like structure with a central cavity, CC resembling the structure of eukaryotic proteasomes. {ECO:0000255|HAMAP- CC Rule:MF_00444}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00444}. CC -!- SIMILARITY: Belongs to the peptidase S14 family. {ECO:0000255|HAMAP- CC Rule:MF_00444}.
