CC   -!- FUNCTION: Part of a stress-induced multi-chaperone system, it is
CC       involved in the recovery of the cell from heat-induced damage, in
CC       cooperation with DnaK, DnaJ and GrpE. Acts before DnaK, in the
CC       processing of protein aggregates. Protein binding stimulates the ATPase
CC       activity; ATP hydrolysis unfolds the denatured protein aggregates,
CC       which probably helps expose new hydrophobic binding sites on the
CC       surface of ClpB-bound aggregates, contributing to the solubilization
CC       and refolding of denatured protein aggregates by DnaK (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBUNIT: Homohexamer. The oligomerization is ATP-dependent (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC   -!- INDUCTION: Induced by low temperature. {ECO:0000269|PubMed:11916687}.
CC   -!- DOMAIN: The Clp repeat (R) domain probably functions as a substrate-
CC       discriminating domain, recruiting aggregated proteins to the ClpB
CC       hexamer and/or stabilizing bound proteins. The NBD2 domain is
CC       responsible for oligomerization, whereas the NBD1 domain stabilizes the
CC       hexamer probably in an ATP-dependent manner. The movement of the
CC       coiled-coil domain is essential for ClpB ability to rescue proteins
CC       from an aggregated state, probably by pulling apart large aggregated
CC       proteins, which are bound between the coiled-coils motifs of adjacent
CC       ClpB subunits in the functional hexamer (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the ClpA/ClpB family. {ECO:0000305}.
