Substitution of Sigma Factor and Control of Transcription

Abstract. Bacteria are known to cope with environmental changes by using alternative sigma factors binding to RNA polymerase core enzyme. Sigma factor is one of the targets to modify transcription regulation in bacteria and to influence production capacities.

Prokaryotic Gene Regulation by Sigma Factors and RNA

Sigma factors provide promoter recognition specificity to RNA polymerase holoenzyme, contribute to DNA strand separation, and then dissociate from the core enzyme following transcription initiation. As the regulon of a single sigma factor can be composed of hundreds of genes, sigma factors can provide effective mechanisms for simultaneously

Roles of DNA Sequence and Sigma A Factor in Transcription

Transcription factors (TFs) are molecules involved in regulating gene expression. They are usually proteins, although they can also consist of short, non-coding RNA. TFs are also usually found working in groups or complexes, forming multiple interactions that allow for varying degrees of control

Roles of DNA Sequence and Sigma A Factor in Transcription

A sigma factor is a protein needed only for initiation of RNA synthesis in bacteria. Sigma factors provide promoter recognition specificity to the RNA polymerase (RNAP) and contribute to DNA strand separation, then dissociating from the RNA polymerase core enzyme following transcription initiation. The RNA polymerase core associates with the

The Functional and Regulatory Roles of Sigma Factors in

A sigma factor (this term is used more often than sigma subunit) is a protein binding to the RNA polymerase, which "promotes" the expression of specific genes of the DNA, by binding or …

Alternative Sigma Factors and Their Roles in Bacterial

After sigma was released, addition of core polymerase with rifampicin reduced the free sigma to less than 15%, indicating that the released sigma was accessible to the added core enzyme. Thus these studies have provided physical evidence for the sigma cycle during in vitro transcription.
