The Agrobacterium tumefaciens DnaK: ATPase cycle, oligomeric state and chaperone properties.

Abstract excerpt

DnaK is a molecular chaperone that promotes cell survival during stress by preventing protein misfolding. The chaperone activity is regulated by nucleotide binding and hydrolysis events in the N-terminal ATPase domain, which in turn mediate substrate binding and release in the C-terminal substrate binding domain. In this study we determined that ATP hydrolysis was the rate limiting step in the ATPase cycle of...
