This probable domain is found in bacterial transcriptional regulators such as DeoR and SorC. These proteins have an amino-terminal helix-turn-helix Pfam:PF00325 that binds to DNA. This domain is probably the ligand regulator binding region. SorC is regulated by sorbose and other members of this family are likely to be regulated by other sugar substrates.	Domain

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.	Domain
