Clp protease ClpX; ATPase and specificity subunit of the ClpA-ClpP ATP dependent serine protease; directs protease to specific substrates; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the ClpA/ClpB family.

Clp protease ClpV; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the ClpA/ClpB family.

Heat shock protein 90; Molecular chaperone. Has ATPase activity.

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

Molecular chaperone 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, [...]

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 chaperone IbpB; Associates with aggregated proteins, together with IbpA, to stabilize and protect them from irreversible denaturation and extensive proteolysis during heat shock and oxidative stress. Aggregated proteins bound to the IbpAB complex are more efficiently refolded and reactivated by the ATP-dependent chaperone systems ClpB and DnaK/DnaJ/GrpE. Its activity is ATP-independent.

ATP-dependent protease subunit HslV; Protease subunit of a proteasome-like degradation complex believed to be a general protein degrading machinery.

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