Nickel-responsive pleiotropic regulator (HpNikR)
The HpNikR protein is a pleiotropic regulator from Helicobacter pylori. In presence of nickel it can acts as an activator or a repressor depending of the specific promoter that contains its operator site. It consists of two dimeric DNA binding domains separated by a tetrameric regulatory domain that binds nickel. This domain corresponds to the C-terminal regulatory domain which contains four nickel binding sites at the tetramer interface. Binding nickel, then a conformational change allows it to activate or repress trascription.
