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] [CTHL3_BOVIN] Exerts, in vitro, a potent antimicrobial activity. Probably due to an impairment of the function of the respiratory chain and of energy-dependent activities in the inner membrane of susceptible microorganisms.

Publication Abstract from PubMed

Bacterial resistance against common antibiotics is an increasing health problem. New pharmaceuticals for the treatment of infections caused by resistant pathogens are needed. Small proline-rich antimicrobial peptides (PrAMPs) from insects are known to bind intracellularly to the conventional substrate binding cleft of the E. coli Hsp70 chaperone DnaK. Furthermore, bactenecins from mammals, members of the cathelicidin family, also contain potential DnaK binding sites. Crystal structures of bovine and sheep Bac7 in complex with the DnaK substrate binding domain show that the peptides bind in the forward binding mode with a leucine positioned in the central hydrophobic pocket. In most structures, proline and arginine residues preceding leucine occupy the hydrophobic DnaK binding sites -1 and -2. Within bovine Bac7, four potential DnaK binding sites were identified.
