Heat shock protein, Hsp20 family; Identified by match to protein family HMM PF00011; Belongs to the small heat shock protein (HSP20) family.

ATP-dependent Clp protease, ATP-binding subunit ClpB; Part of a stress-induced multi-chaperone system, it is involved in the recovery of the cell from heat-induced damage, in cooperation with DnaK, DnaJ and GrpE. Acts before DnaK, in the processing of protein aggregates. Protein binding stimulates the ATPase activity; ATP hydrolysis unfolds the denatured protein aggregates, which probably helps expose new hydrophobic binding sites on the surface of ClpB-bound aggregates, contributing to the solubilization and refolding of denatured protein aggregates by DnaK (By similarity). Belongs to [...]

ATP-dependent Clp protease, ATP-binding subunit ClpA; Identified by similarity to SP:P15716; match to protein family HMM PF00004; match to protein family HMM PF02861; Belongs to the ClpA/ClpB family.

Heat shock protein HtpG; Molecular chaperone. Has ATPase activity; Belongs to the heat shock protein 90 family.

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

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, Hsp20 family; Identified by match to protein family HMM PF00011; Belongs to the small heat shock protein (HSP20) family.

Phage shock protein C; Identified by similarity to SP:P23855; match to protein family HMM PF04024.

ATP-dependent protease 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.
