Mutational Analysis of Escherichia coli Heat Shock Transcription Factor Sigma 32 Reveals Similarities with Sigma 70 in Recognition of the −35 Promoter Element and Differences in Promoter DNA Melting and −10 Recognition
Upon the exposure of Escherichia coli to high temperature (heat shock), cellular levels of the transcription factor σ(32) rise greatly, resulting in the increased formation of the σ(32) holoenzyme, which is capable of transcription initiation at heat shock promoters. Higher levels of heat shock prot...
