PF08281 | Sigma-70, region 4 (Sigma70_r4_2) | 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]. | Domain | |
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 |
