ATP-dependent Clp protease, proteolytic subunit ClpP; Cleaves peptides in various proteins in a process that requires ATP hydrolysis. Has a chymotrypsin-like activity. Plays a major role in the degradation of misfolded proteins. Belongs to the peptidase S14 family.

DnaJ protein; 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, DnaK and Gr [...]

Co-chaperone 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-depend [...]

Scaffolding protease; Belongs to the peptidase S14 family.

Conserved hypothetical protein; Enables the recognition and targeting of unfolded and aggregated proteins to the ClpC protease or to other proteins involved in proteolysis.

Conserved hypothetical protein; Belongs to the small heat shock protein (HSP20) family.

Conserved hypothetical protein; Negative regulator of clpC, clpB and clpP transcription by binding directly and specifically to their promoter region.

Chaperonin, 10 kDa, GroES, putative; Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter.

ATP:guanido phosphotransferase, C-terminal catalytic domain protein; Catalyzes the specific phosphorylation of arginine residues in proteins (By similarity). Is required for stress tolerance and virulence in S.aureus. Acts as a modulator of the repressor activity of CtsR upon heavy metal and oxidative stress caused by these metal ions.
