clpB | Chaperone; 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; Belongs to the ClpA/ClpB family. (854 aa) | ||||
lon | ATP-dependent protease; 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. (806 aa) | ||||
htpG | Heat shock protein 90; Molecular chaperone. Has ATPase activity. (634 aa) | ||||
AGE26272.1 | COG0071 Molecular chaperone (small heat shock protein). (152 aa) | ||||
lon-2 | 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. (798 aa) | ||||
clpX | ATP-dependent protease ATP-binding subunit ClpX; ATP-dependent specificity component of the Clp protease. It directs the protease to specific substrates. Can perform chaperone functions in the absence of ClpP. (427 aa) | ||||
clpP | ATP-dependent Clp protease proteolytic subunit; 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. (211 aa) | ||||
groEL | Chaperonin GroEL; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions. (548 aa) | ||||
groES | Co-chaperonin GroES; Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter. (98 aa) | ||||
dnaJ | Chaperone 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, D [...] (374 aa) | ||||
dnaK | Molecular chaperone DnaK; Acts as a chaperone; Belongs to the heat shock protein 70 family. (638 aa) | ||||
grpE | 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- [...] (186 aa) | ||||
hslU | ATP-dependent protease ATP-binding subunit HslU; 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. (445 aa) | ||||
hslV | ATP-dependent protease subunit HslV; Protease subunit of a proteasome-like degradation complex believed to be a general protein degrading machinery. (176 aa) | ||||
AGE28796.1 | Heat shock protein, Hsp70 family; COG0443 Molecular chaperone. (422 aa) | ||||
AGE28797.1 | Curved DNA-binding protein; COG2214 DnaJ-class molecular chaperone. (312 aa) |
