Helix-turn-helix; This large family of DNA binding helix-turn helix proteins includes Cro and CI. Within the protein Swiss:Q5F9C2, the full protein fold incorporates a helix-turn-helix motif, but the function of this member is unlikely to be that of a DNA-binding regulator, the function of most other members, so is not necessarily characteriztic of the whole family.

transcriptional regulator, y4mF family; Members of this family belong to a clade of helix-turn-helix DNA-binding proteins, among the larger family pfam01381 (HTH_3; Helix-turn-helix). Members are similar in sequence to the HipB protein of E. coli. Genes for members of the seed alignment for this protein family were found to be closely linked to genes encoding proteins related to HipA. The HibBA operon appears to have some features in common with toxin-antitoxin post-segregational killing systems. [Regulatory functions, DNA interactions]
