Abstract excerpt
The dnaK operon of Streptomyces coelicolor encodes the DnaK chaperone machine and the negative autoregulator HspR, which confers repression of the operon by binding to several inverted repeat sequences in the promoter region, dnaKp. Previous in vitro studies demonstrated that DnaK forms a specific complex with HspR bound to its operator sequences in dnaKp, and a model was proposed in which DnaK functions as a...
