Immun. 72:1364-1373(2004). CC -!- FUNCTION: Participates actively in the response to hyperosmotic CC and heat shock by preventing the aggregation of stress-denatured CC proteins and by disaggregating proteins, also in an autonomous, CC dnaK-independent fashion. Unfolded proteins bind initially to CC dnaJ; upon interaction with the dnaJ-bound protein, dnaK CC hydrolyzes its bound ATP, resulting in the formation of a stable CC complex. GrpE releases ADP from dnaK; ATP binding to dnaK triggers CC the release of the substrate protein, thus completing the reaction CC cycle. Several rounds of ATP-dependent interactions between dnaJ, CC dnaK and grpE are required for fully efficient folding. Also CC involved, together with dnaK and grpE, in the DNA replication of CC plasmids through activation of initiation proteins (By CC similarity). Necessary for invasion of epithelial cells, secretion CC of invasion proteins and proliferation within macrophages. CC -!- COFACTOR: Binds 2 zinc ions per monomer (By similarity). CC -!- SUBUNIT: Homodimer (By similarity). CC -!- SUBCELLULAR LOCATION: Cytoplasm (Probable). CC -!- INDUCTION: By heat shock under the control of the htpR regulatory CC protein (By similarity). 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 CC center 2 is essential for interaction with dnaK and for dnaJ CC activity (By similarity). CC -!- SIMILARITY: Belongs to the dnaJ family. CC -!- SIMILARITY: Contains 1 CR-type zinc finger. CC -!- SIMILARITY: Contains 1 J domain.
