The sigmaS (RpoS) subunit of RNA polymerase in Escherichia coli is a key master regulator which allows this bacterial model organism and important pathogen to adapt to and survive environmentally rough times.

The Escherichia coli RNA polymerase (RNAP) is a multi-subunit enzyme composed of five subunits including α (two copies), β, β' and ω subunits. These five subunits form the RNAP core enzyme responsible for RNA synthesis using DNA as template and ribonucleotide (rNTP) as substrate.

The sigma (σ) subunit of RNA polymerase (RNAP) controls all transcription initiation steps, from recognition of the −10/−35 promoter elements, upon formation of the closed promoter complex (RPc), to stabilization of the open promoter complex (RPo) and stimulation of the primary steps in RNA synthesis.

RNA Polymerase, abbreviated as RNA Pol or RNAP, is an enzyme in molecular biology that synthesises RNA from a DNA template. During the process of transcription, RNA polymerase copies the sequence of DNA into an RNA sequence with the help of the enzyme helicase that opens up the wounded DNA strands.

The sigma (σ) subunit binds to the core RNA polymerase enzyme. The function of this sigma factor is to recognize and bind to the promoter of a gene so that transcription can be initiated.

Sigma factors are multi-domain subunits of bacterial RNA polymerase (RNAP) that play critical roles in transcription initiation, including the recognition and opening of promoters as well as the initial steps in RNA synthesis.

Transcription by E. coli RNA polymerase. The polymerase initially binds nonspecifically to DNA and migrates along the molecule until the σ subunit binds to the -35 and -10 promoter elements, forming a closed-promoter complex.
