RNA pol σ 70 Activators

The class of σ70 Activators primarily includes compounds that impact RNA polymerase activity and thereby potentially influence σ70. Rifampicin, Actinomycin D, 6-Azauracil, Deoxynojirimycin, LY-255283, Tagetitoxin, and Streptolydigin are all inhibitors of RNA polymerase. Their inhibitory action on RNA polymerase can influence transcription processes, which may indirectly affect σ70, a key component of the RNA polymerase holoenzyme in bacteria.

The proteins DksA, ppGpp, NusA, and NusG interact with RNA polymerase and can also indirectly influence σ70. DksA and ppGpp are known to work together to regulate transcription in response to nutrient availability, whereas NusA and NusG are involved in transcription termination and antitermination. While each of these compounds and proteins can influence RNA polymerase activity and potentially σ70, they do so through different mechanisms and in response to different cellular conditions. As such, the σ70 Activators class represents a diverse array of compounds and proteins that can indirectly influence σ70 and its role in the initiation of transcription.
