This is the C-terminal hood domain found in Heterocyst differentiation control protein (HetR). HetR-C binds to PatS peptide. Two PatS6 peptides bind to the lateral clefts of HetR-Hood domain, and trigger significant conformational changes of the flap domain, resulting in dissociation of the auxiliary alpha-helix and eventually release of HetR from the DNA major grove and termination of transcription [1].
