Requires the exposure of 32 sites to bind DnaJ. Significance: This model can be applied to chaperone action in helping newly synthesized polypeptides to fold. Escherichia coli heat shock transcription factor 32 is rapidly degraded by ATP-dependent proteases, such as FtsH and ClpYQ. Although the DnaK chaperone system (DnaK, DnaJ, and GrpE) promotes 32 degradation in vivo, the precise mechanism that
