Probable 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 round [...]

Probable chaperon protein HtpG; Molecular chaperone. Has ATPase activity.

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 [...]

Putative chaperone protein dnaJ. homology to dnaJ of E. coli of 32% (sprot|DNAJ_ECOLI) Acts as a co-chaperone. Stimulates jointly with grpE the ATPase activity of dnaK (By similarity). Pfam: DnaJ domain, DnaJ central domain (4 repeats), DnaJ Cterminal region no singal peptide no TMHs; Family membership.

Hypothetical protein which carries at the C-terminus a DnaJ N-terminal domain. InterPro: DnaJ N-terminal domain (IPR001623) Pfam: DnaJ domain no signal peptide no TMHs.

ATP-dependent Clp protease ATP-binding subunit clpA. Homology to clpA of E. coli of 63% (sprot|CLPA_ECOLI). ATP-dependent specificity component of the clpP protease. It directs the protease to specific substrates. The primary function of the clpA-clpP complex appears to be the degradation of unfolded or abnormal proteins. InterPro: AAA-protein (ATPases associated with various cellular activities)(IPR003959); AAA ATPase superfamily (IPR003593); Clp amino terminus (IPR004176); chaperonins clpA/B (IPR001270); Bacterial typeII secretion system protein E (IPR001482) Pfam: Clp amino ternimal [...]

Probable 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; Belongs to the ClpA/ClpB family.

Putative ATP-dependent Clp protease, ATP-binding subunit ClpB. Homology to clpB of E. coli of 38% (sprot|CLPB_ECOLI). The protein is thought to be subunits of ATP-dependent proteases which act as chaperones to target the proteases to substrates. Pfam: ATPsae family associated with various cellular activites no signal peptide no TMHs; High confidence in function and specificity; Belongs to the ClpA/ClpB family.

50S ribosomal protein L16; Binds 23S rRNA and is also seen to make contacts with the A and possibly P site tRNAs; Belongs to the universal ribosomal protein uL16 family.
