Figure 4

Structural comparison of HlyIIR with other members of the TetR family. (a) Superimposed N-terminal (left) and C-terminal (right) domains of HlyIIR (red) with QacR (PDB code 1JT0, blue) and EthR (1T56, green). (b) Architecture of the dimerisation interface in HlyIIR (left), EthR (middle) and QacR (right). Top and bottom: two views related by a 90° rotation around the vertical axis. Helices from two subunits of the dimer are shown in blue and red. (c) Schematic representation of the HlyIIR complex with the 22 bp B-form DNA. The DNA molecule is shown as a van der Waals model and the HlyIIR dimer is shown as ribbons.
