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.
CC {ECO:0000256|ARBA:ARBA00025613}.
CC -!- SUBUNIT: Homohexamer. The oligomerization is ATP-dependent.
