  • 功能：
    Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the primary sigma factor during exponential growth. Preferentially transcribes genes associated with fast growth, such as ribosomal operons, other protein-synthesis related genes, rRNA- and tRNA-encoding genes and prfB.

    12. study found that although Rob makes fewer interactions with sigma(70) R4 than SoxS, the 2 proteins make the same position-dependent interactions; Rob occludes sigma(70) R4 from binding the -35 hexamer, just as does SoxS; thus, the C-terminal domain does not substantially alter the way Rob interacts with sigma(70) R4 at class II promoters PMID: 22465792

    30. sigma(70) NCR/beta' interaction facilitates promoter escape and hinders early elongation pausing, in contrast to the sigma(2)/beta' coiled-coil interaction, which has opposite effects. PMID: 17332752
