Figure 2. Structure of the TR D355R mutant dimer. (A) Cartoon representation of the dimer. The two TR monomers are shown in green (helixes are numbered) and yellow. The N- and C-termini of each LBD are labeled. Residues H412, H413, R355, E324, E326, R338, and sulfate ion at the dimer interface are shown as stick models and orange sphere, respectively. The bound hormone is shown as space-filling model in dark gray. The two boxed regions indicate the crucial polar interactions at the dimer interface (shown in detail on Panel B). (B) Network of contacting interfacial residues from two sites at the dimer interface. Residues are shown as stick models. Sulfate ion and water are drawn as stick model and sphere, respectively. Contacts between interacting residues and ions are indicated. The electron density corresponding to the sulfate ion (black mesh) in the 2Fo-Fc map is contoured at 2.0 . (C) Polar dimer interface. The intermolecular residues are in surface representation for the green monomer, and in stick representation for the yellow monomer. Shared at interface water molecules are depicted as cyan dotted spheres. Figures were prepared with PyMOL from DeLano Scientific (http://www.pymol.org).
