Thermoregulation of Escherichia coli hchA transcript stability.
The conserved chaperone Hsp31 of Escherichia coli is transcribed at low temperatures by sigma(S) and repressed by H-NS, whereas at high temperature, transcription is by sigma70 independently of both sigma(S) and H-NS. Here we present evidence for an additional, novel, temperature-dependent control of Hsp31 expression by increased transcript stability.
