Fig 4. Structure and topology plot of ligand-free full-length DasR.

Fig 4

(a) DasR dimer without DNA or a potential effector molecule with the monomers coloured in blue and light grey. (b) Topology plot of full-length DasR in the ligand-free state. Secondary structure elements are displayed as blue cylinders (α-helices) and arrows (β-strands). The linker segment between the DBD and EBD is highlighted in bold. (c) Closeup view of the linker segment between the DBD and EBD in ligand-free DasR. Residues 86–96 of the linker segment are shown as stick model with the corresponding 2Fo-Fc electron density (grey mesh) contoured at 1 σ to emphasize the well-ordered secondary structure in this region.
