HslU--HslV peptidase ATPase subunit; ATPase subunit of a proteasome-like degradation complex; this subunit has chaperone activity. The binding of ATP and its subsequent hydrolysis by HslU are essential for unfolding of protein substrates subsequently hydrolyzed by HslV. HslU recognizes the N-terminal part of its protein substrates and unfolds these before they are guided to HslV for hydrolysis.

HslU--HslV peptidase proteolytic subunit; Protease subunit of a proteasome-like degradation complex believed to be a general protein degrading machinery.

Nucleotide exchange factor 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 [...]

Molecular chaperone HtpG; Molecular chaperone. Has ATPase activity.

Thioredoxin-disulfide reductase; Derived by automated computational analysis using gene prediction method: Protein Homology.

Membrane protein FxsA; Derived by automated computational analysis using gene prediction method: Protein Homology.

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

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, [...]

Protein-tyrosine-phosphatase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the low molecular weight phosphotyrosine protein phosphatase family.
