General transcription factors (GTFs), also known as basal transcriptional factors, are a class of protein transcription factors that bind to specific sites (promoter) on DNA to activate transcription of genetic information from DNA to messenger RNA.
Introduction. Sigma factors are subunits of all bacterial RNA polymerases that are responsible for determining the specificity of promoter DNA binding and efficient initiation of RNA synthesis (transcription). The first sigma factor discovered was the sigma70 (Ï 70) of the highly studied bacterium Escherichia coli.
