Specificity factor : ウィキペディア英語版 | Specificity factor The sigma subunit of the ''Escherichia coli'' RNA polymerase holoenzyme is the specificity factor that mediates the promoter recognition and binding σ subunit of molecular weight 70 kDa. Under some conditions, some of the 70-kDa subunits are replaced by one of the other, more-specific factors. For instance, when bacteria are subjected to heat stress, some of the 70-kDa subunits are replaced by a 32-kDa subunit; when bound to σ32, RNA polymerase is directed to a specialized set of promoters with a different consensus sequence.
