NolR Repressor Bound to DNA

Loading video...

Caption: The helix-turn-helix motif of the protein NolR consists of alpha helices (pale blue and pink) separated by a short string of amino acids (the turn). The helices are spaced to fit into the major groove of a DNA molecule (the white and gray double helix below NolR) and bind to "consensus sequences" in the DNA (purple and red), common genetic sequences found in all the genes NolR binds.
