Synergistic Binding of DnaJ and DnaK Chaperones to Heat Shock Transcription Factor σ(32) Ensures Its Characteristic High Metabolic Instability: IMPLICATIONS FOR HEAT SHOCK PROTEIN 70 (Hsp70)-Hsp40 MODE OF FUNCTION

Escherichia coli heat shock transcription factor σ(32) is rapidly degraded by ATP-dependent proteases, such as FtsH and ClpYQ. Although the DnaK chaperone system (DnaK, DnaJ, and GrpE) promotes σ(32) degradation in vivo, the precise mechanism that is involved remains unknown. Our previous results in...
