Protein
Chaperone protein DnaJ
Gene
dnaJ, BR2126, BS1330_I2120
Organism
Brucella suis biovar 1 (strain 1330)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

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, DnaK and GrpE are required for fully efficient folding. Also involved, together with DnaK and GrpE, in the DNA replication of plasmids through activation of initiation proteins By similarity.UniRule annotation

Domaini

The J domain is necessary and sufficient to stimulate DnaK ATPase activity. Zinc center 1 plays an important role in the autonomous, DnaK-independent chaperone activity of DnaJ. Zinc center 2 is essential for interaction with DnaK and for DnaJ activity By similarity.UniRule annotation

Sequence similaritiesi

Belongs to the DnaJ family.
Contains 1 J domain.
