Function

DNAK_ECOLI Plays an essential role in the initiation of phage lambda DNA replication, where it acts in an ATP-dependent fashion with the DnaJ protein to release lambda O and P proteins from the preprimosomal complex. DnaK is also involved in chromosomal DNA replication, possibly through an analogous interaction with the DnaA protein. Also participates actively in the response to hyperosmotic shock.[HAMAP-Rule:MF_00332]

Publication Abstract from PubMed

The solution structure of the 21 kDa substrate-binding domain of the Escherichia coli Hsp70-chaperone protein DnaK (DnaK 386-561) has been determined to a precision of 1.00 A (backbone of the beta-domain) from 1075 experimental restraints obtained from multinuclear, multidimensional NMR experiments. The domain is observed to bind to its own C-terminus and offers a preview of the interaction of this chaperone with other proteins. The bound protein region is tightly held at a single amino acid position (a leucyl residue) that is buried in a deep pocket lined with conserved hydrophobic residues. A second hydrophobic binding site was identified using paramagnetically labeled peptides. It is located in a region close to the N-terminus of the domain and may constitute the allosteric region that links substrate-binding affinity with nucleotide binding in the Hsp70 chaperones.
