CC -!- FUNCTION: ATP-dependent specificity component of the Clp protease. It
CC directs the protease to specific substrates. Can perform chaperone
CC functions in the absence of ClpP. {ECO:0000255|HAMAP-Rule:MF_00175}.
CC -!- SUBUNIT: Component of the ClpX-ClpP complex. Forms a hexameric ring
CC that, in the presence of ATP, binds to fourteen ClpP subunits assembled
CC into a disk-like structure with a central cavity, resembling the
CC structure of eukaryotic proteasomes. {ECO:0000255|HAMAP-Rule:MF_00175}.
CC -!- SIMILARITY: Belongs to the ClpX chaperone family. {ECO:0000255|HAMAP-
CC Rule:MF_00175}.
