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.

Abstract

Upon the exposure of Escherichia coli to high temperature (heat shock), cellular levels of the transcription factor sigma32 rise greatly, resulting in the increased formation of the sigma32 holoenzyme, which is capable of transcription initiation at heat shock promoters. Higher levels of heat shock proteins render the cell better able to cope with the… (More)
