Figure 3
Superposition of the structures of bluetongue virus VP4 enzyme with PDB entries 2jha
(green) and 2jhp
(blue) (Sutton et al., 2007), which were solved at 3.4 and 2.5 Å, respectively. The graph shows the resultant R (solid) and Rfree (dashed) values from ten iterations of refinement of the low-resolution structure 2jha
. Results are shown with (red) and without (black) external restraints, using 2jhp
as prior information. This figure was produced using PROSMART to superpose the structures, PyMOL (DeLano, 2002) to display the structures and the software package R (R Development Core Team, 2007) to generate the graph. |
