Universal functions of the σ finger in alternative σ factors during transcription initiation by bacterial RNA polymerase
2021

The bacterial σ factor plays the central role in promoter recognition by RNA polymerase (RNAP). The primary σ factor, involved in transcription of housekeeping genes, was also shown to participate in the initiation of RNA synthesis and promoter escape by RNAP. In the open promoter complex, the σ finger formed by σ region 3.2 directly interacts with the template DNA strand upstream of the transcription start site. Here, we analyzed the role of the σ finger in transcription initiation by four
