CC   -!- FUNCTION: Participates actively in the response to hyperosmotic and
CC       heat shock by preventing the aggregation of stress-denatured proteins,
CC       in association with DnaK and GrpE. It is the nucleotide exchange factor
CC       for DnaK and may function as a thermosensor. Unfolded proteins bind
CC       initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK
CC       hydrolyzes its bound ATP, resulting in the formation of a stable
CC       complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the
CC       release of the substrate protein, thus completing the reaction cycle.
CC       Several rounds of ATP-dependent interactions between DnaJ, DnaK and
CC       GrpE are required for fully efficient folding. {ECO:0000255|HAMAP-
CC       Rule:MF_01151}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01151}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01151}.
CC   -!- SIMILARITY: Belongs to the GrpE family. {ECO:0000255|HAMAP-
CC       Rule:MF_01151}.
