  2. Bacterial transcription - Wikipedia

    en.wikipedia.org/wiki/Bacterial_transcription

    Bacteria have a σ-factor that detects and binds to promoter sites but eukaryotes do not need a σ-factor. Instead, eukaryotes have transcription factors that allow the recognition and binding of promoter sites. [2] Overall, transcription within bacteria is a highly regulated process that is controlled by the integration of many signals at a ...

  3. GntR-like bacterial transcription factors - Wikipedia

    en.wikipedia.org/wiki/GntR-like_bacterial...

    Many bacterial transcription regulation proteins bind DNA through a helix-turn-helix (HTH) motif, which can be classified into subfamilies on the basis of sequence similarities. The HTH GntR family has many members distributed among diverse bacterial groups that regulate various biological processes.

  4. CollecTF - Wikipedia

    en.wikipedia.org/wiki/CollecTF

    CollecTF is a database of transcription factor binding sites in the Bacteria domain. [1]CollecTF compiles only experimentally validated TF-binding sites. This is accomplished through the manual curation of peer-reviewed literature with a special focus on the experimental process used to identify TF-binding sites.

  5. Pribnow box - Wikipedia

    en.wikipedia.org/wiki/Pribnow_box

    It is also commonly called the -10 sequence or element, because it is centered roughly ten base pairs upstream from the site of initiation of transcription. The Pribnow box has a function similar to the TATA box that occurs in promoters in eukaryotes and archaea : it is recognized and bound by a subunit of RNA polymerase during initiation of ...

  6. Sigma factor - Wikipedia

    en.wikipedia.org/wiki/Sigma_factor

    A sigma factorfactor or specificity factor) is a protein needed for initiation of transcription in bacteria. [1] [2] It is a bacterial transcription initiation factor that enables specific binding of RNA polymerase (RNAP) to gene promoters. It is homologous to archaeal transcription factor B and to eukaryotic factor TFIIB. [3]

  7. Rho factor - Wikipedia

    en.wikipedia.org/wiki/Rho_factor

    A ρ factor (Rho factor) is a bacterial protein involved in the termination of transcription. [1] Rho factor binds to the transcription terminator pause site, an exposed region of single stranded RNA (a stretch of 72 nucleotides) after the open reading frame at C-rich/G-poor sequences that lack obvious secondary structure.

  8. Transcription factor - Wikipedia

    en.wikipedia.org/wiki/Transcription_factor

    Other transcription factors differentially regulate the expression of various genes by binding to enhancer regions of DNA adjacent to regulated genes. These transcription factors are critical to making sure that genes are expressed in the right cell at the right time and in the right amount, depending on the changing requirements of the organism.

  9. TATA box - Wikipedia

    en.wikipedia.org/wiki/TATA_box

    Transcription is initiated at the TATA box in TATA-containing genes. The TATA box is the binding site of the TATA-binding protein (TBP) and other transcription factors in some eukaryotic genes. Gene transcription by RNA polymerase II depends on the regulation of the core promoter by long-range regulatory elements such as enhancers and silencers ...
