Research output: Contribution to journalArticlepeer-review


The conserved chaperone Hsp31 of Escherichia coli is transcribed at low temperatures by σS and repressed by H-NS, whereas at high temperature, transcription is by σ70 independently of both σS and H-NS. Here we present evidence for an additional, novel, temperature-dependent control of Hsp31 expression by increased transcript stability.
