Start learning WebApr 7, 2024 · Transcription begins with the binding of an RNAP in the presence of general transcription factors to the promoter region upstream of the transcription start site on the DNA. Prokaryotic RNAP binds with a sigma factor, while eukaryotic RNA polymerases can interact with a number of transcription factors as well as activator and repressor proteins.

WebSigma 54 An alternative sigma factor that control nitrogen regulated genes is 54 kDa and designated sigma 54. The sigma 54 family is also widely represented in many different bacteria and controls in many different bacteria and controls a variety of function including nitrogen metabolism, degradative enzyme synthesis and flagellar genes. 11. WebJul 27, 2024 · The poster, in his title, asks whether the sigma factor is a transcription factor. The answer to this is yes… and no. And calling it a transcription factor doesn’t really help much. Yes, it is a transcription factor because it is necessary for transcription and different sigma factors can impart a certain specificity to bacterial transcription. WebMar 31, 2024 · In MATa cells transformed with a plasmid in which the λScG7 sigma element was inserted just upstream of a gene coding for the intracellular form of invertase (SUC2) lacking its own promoter, a new poly(A) + RNA (2.2 kilobases) appeared in response to alpha-factor that hybridized to both sigma and SUC2 probes, and intracellular invertase ... hope athletics
