FIGURE 1.

Structure of the thermosensing regulator RovA. A, illustration of the RovA dimer. B, superposition of three RovA dimers found in the asymmetric unit. The three different types of dimers (AB, CD, and EF) are shown in blue, green, and red. The RovA monomers could be built despite the flexible wing domain. C and D, schematic representation of a RovA dimer in complex with DNA from the front and the side, respectively. α-Helices, β-sheets, and amino acids implicated in thermosensing and RovA stability are indicated. One monomer is shown in red and the other in blue.
