 14-52 7.83e-03

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.
