A Ribbon representation of the monomer, dimer, and tetramer structures in which the topology of the MarR family is labeled. B The wing Helix turn Helix (wHTH) binding motif of ScoC. Each monomer of ScoC contains one motif unit shown in red. C The ScoC tetramerization contact region. The interactions forming the dimer-dimer interface include ten hydrogen bonds and four salt bridges involving residues: Tyr139, Lys141, Glu144, Cys150, and the backbone of Leu138.
