| PF04542 | Sigma-70 region 2 (Sigma70_r2) | Sigma-70 region 2 | Region 2 of sigma-70 is the most conserved region of the entire protein. All members of this class of sigma-factor contain region 2. The high conservation is due to region 2 containing both the -10 promoter recognition helix and the primary core RNA ... | Domain | |
| 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 | |
| PF04546 | Sigma-70, non-essential region (Sigma70_ner) | Sigma-70, non-essential region | The domain is found in the primary vegetative sigma factor. The function of this domain is unclear and can be removed without loss of function. | Domain | |
