Chaperonin 10kD subunit; Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter.

Heat shock protein GrpE; Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins, in association with DnaK and GrpE. It is the nucleotide exchange factor for DnaK and may function as a thermosensor. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the release of the substrate protein, thus completing the reaction cycle. Several rounds of ATP- [...]

Heat shock protein DnaK; Acts as a chaperone; Belongs to the heat shock protein 70 family.

Heat shock protein dnaJ; Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins and by disaggregating proteins, also in an autonomous, DnaK-independent fashion. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the release of the substrate protein, thus completing the reaction cycle. Several rounds of ATP-dependent interactions between DnaJ, [...]

Probable chaperone heat shock protein hptG; Molecular chaperone. Has ATPase activity.

Chaperone protein; Chaperone involved in the maturation of iron-sulfur cluster- containing proteins. Has a low intrinsic ATPase activity which is markedly stimulated by HscB.

Probable heat-shock protein Hsp 70; Identified by sequence similarity; putative; ORF located using Glimmer/GeneMark/Blastx/COG0443.

Chaperonin 60kD subunit; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.

Endopeptidase La; ATP-dependent serine protease that mediates the selective degradation of mutant and abnormal proteins as well as certain short- lived regulatory proteins. Required for cellular homeostasis and for survival from DNA damage and developmental changes induced by stress. Degrades polypeptides processively to yield small peptide fragments that are 5 to 10 amino acids long. Binds to DNA in a double-stranded, site-specific manner.
