Cα-cartoon superimposition of one of the two protomers of dimeric ArsR family metal sensors MtCmtR (shaded green) [102], SaCadC (dark blue) [103], MtNmtR (gold) [101] and SaCzrA (light blue) [68]. All proteins were aligned their HTH-DNA binding motifs with an r.m.s.d. of ∼1 Å for the corresponding 29 Cα atoms. Metal binding residues in each protein are highlighted as spheres on their Cα atoms. A possible movement of the N-terminal extension of MtNmtR is also shown [59].
