PF01381 | Helix-turn-helix (HTH_3) | Helix-turn-helix | This large family of DNA binding helix-turn helix proteins includes Cro Swiss:P03036 and CI Swiss:P03034. 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 ... | Domain | |
