helix-turn-helix domain-containing protein

This family consists of several phage CI repressor proteins and related bacterial sequences. The CI repressor is known to function as a transcriptional switch, determining whether transcription is lytic or lysogenic [1]. [1]. 2370665. Control of gene expression in the temperate coliphage 186. VIII.. Control of lysis and lysogeny by a transcriptional switch. involving face-to-face promoters.. Dodd IB, Kalionis B, Egan JB;. J Mol Biol 1990;214:27-37. (from Pfam)

helix-turn-helix domain-containing protein

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..
