	One of the two functional domains of AdcR is the <scene name='69/694230/Dimerization_domain/3'> dimerization domain</scene>. This domain connects and stabilizes the two pseudosymmetric dimers and is composed of the <scene name='69/694230/Alpha_1/1'>α1 helix</scene>, the C-terminus of the <scene name='69/694230/Alpha_five/1'>α5 helix</scene> , and the <scene name='69/694230/Alpha_6/1'>α6 helix</scene>. This domain is connected to the [https://en.wikipedia.org/wiki/DNA-binding_domain DNA binding domain] by the long α5 helix. The DNA binding domain stabilizes the major and minor groove of DNA via the <scene name='69/694230/Whth_4/7'>winged helix-turn-helix (wHTH)</scene> motif. The binding of Zinc to the <scene name='69/694230/2_binding_sites/4'>Zinc binding pocket</scene> induces a conformational change that allows for a <scene name='69/694230/Hydrogen_bonding_1/4'>hydrogen bond network</scene> between 4 specific residues.
