Protein Family Models

Members of this family contains a DNA-binding helix-turn-helix domain. This family contains many example antitoxins from bacterial toxin-antitoxin systems. These antitoxins are likely to be DNA-binding domains. (from Pfam)

This family represents the conserved barrel domain of the 'cupin' superfamily [1] ('cupa' is the Latin term for a small barrel). [1]. 9573603.

This family represents the arabinose-binding and dimerisation domain of the bacterial gene regulatory protein AraC. The domain is found in conjunction with the helix-turn-helix (HTH) DNA-binding motif Pfam:PF00165. This domain is distantly related to the Cupin domain Pfam:PF00190. [1]. 9103202.

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 that of a DNA-binding regulator, the function of most other members, so is not necessarily characteristic of the whole family [1]. [1]. 20196080. The crystal structure of NGO0477 from Neisseria gonorrhoeae reveals a novel protein fold incorporating a helix-turn-helix motif.
