sigma factor-like helix-turn-helix DNA-binding protein
Region 4 of sigma-70 like sigma-factors are involved in binding to the -35 promoter element via a helix-turn-helix motif [1]. [1]. 11931761. Structure of the bacterial RNA polymerase promoter specificity. sigma subunit.. Campbell EA, Muzzin O, Chlenov M, Sun JL, Olson CA, Weinman O,. Trester-Zedlitz ML, Darst SA;. Mol Cell 2002;9:527-539.

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 families. Therefore there are many false negatives. [1]. 11931761.
