WebJul 1, 2024 · ECFσ are in most cases sequestered and kept inactive by specific anti-sigma factors that respond to environmental stimuli. Upon environmental stresses or specific inducing factors, signaling networks result in the release of the ECFσ, which then recruit the RNAP catalytic core and trigger gene expression of dedicated target regulons. WebSigma factors are initiation factors that promote the attachment of RNA polymerase (RNAP) to specific initiation sites and are then released (PubMed:7889935, PubMed:2691330, PubMed:9159522, PubMed:9159523).
