How a mutation in the gene encoding sigma 70 suppresses the defective heat shock response caused by a mutation in the gene encoding sigma 32.
In Escherichia coli, transcription of the heat shock genes is regulated by sigma 32, the alternative sigma factor directing RNA polymerase to heat shock promoters. sigma 32, encoded by rpoH (htpR), is normally present in limiting amounts in cells. Upon temperature upshift, the amount of sigma 32 tra...
