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}.
