RC STRAIN=ATCC 29342 / M129 / Subtype 1; RX PubMed=8948633; DOI=10.1093/nar/24.22.4420; RA Himmelreich R., Hilbert H., Plagens H., Pirkl E., Li B.-C., Herrmann R.; RT "Complete sequence analysis of the genome of the bacterium Mycoplasma RT pneumoniae."; RL Nucleic Acids Res. 24:4420-4449(1996). CC -!- FUNCTION: Participates actively in the response to hyperosmotic and CC heat shock by preventing the aggregation of stress-denatured proteins CC and by disaggregating proteins, also in an autonomous, DnaK-independent CC fashion. Unfolded proteins bind initially to DnaJ; upon interaction CC with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting CC in the formation of a stable complex. GrpE releases ADP from DnaK; ATP CC binding to DnaK triggers the release of the substrate protein, thus CC completing the reaction cycle. Several rounds of ATP-dependent CC interactions between DnaJ, DnaK and GrpE are required for fully CC efficient folding. Also involved, together with DnaK and GrpE, in the CC DNA replication of plasmids through activation of initiation proteins. CC {ECO:0000255|HAMAP-Rule:MF_01152}. CC -!- COFACTOR: CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000255|HAMAP- CC Rule:MF_01152}; CC Note=Binds 2 Zn(2+) ions per monomer. {ECO:0000255|HAMAP- CC Rule:MF_01152}; CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01152}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01152}. CC -!- DOMAIN: The J domain is necessary and sufficient to stimulate DnaK CC ATPase activity. Zinc center 1 plays an important role in the CC autonomous, DnaK-independent chaperone activity of DnaJ. Zinc center 2 CC is essential for interaction with DnaK and for DnaJ activity. CC {ECO:0000255|HAMAP-Rule:MF_01152}. CC -!- SIMILARITY: Belongs to the DnaJ family. {ECO:0000255|HAMAP- CC Rule:MF_01152}.
