The methionine repressor is a helix-turn-helix protein. The helix-turn-helix motif is a structural motif that is found in many DNA-binding proteins. It consists of two alpha helices that are connected by a turn. The first helix is typically involved in binding to the DNA, while the second helix is involved in dimerization.
