C [auth A], D | PF04545 | Sigma-70, region 4 (Sigma70_r4) | Sigma-70, region 4 | Region 4 of sigma-70 like sigma-factors are involved in binding to the -35 promoter element via a helix-turn-helix motif [1]. Due to the way Pfam works, the threshold has been set artificially high to prevent overlaps with other helix-turn-helix fami ... | Domain |
