Loosening the binding between polymerase and non-specific site is important to confer higher specificity. In Bacillus subtilis what is responsible for this action?

Loosening the binding between polymerase and non-specific site is important to confer higher specificity. In Bacillus subtilis what is responsible for this action? Correct Answer Delta subunit

While σ70 in E. coli has an extra 245 amino acid that helps it to loosen the polymerase from non-specific site, σ43 in Bacillus subtilis lacks it. Thus, it needs another subunit of core polymerase- delta subunit to perform this function.
