FIG. 5.

(a)Structure-based sequence alignment was performed using the program O (18). The secondary structural elements and the sequence numbering for VP26 and VP28 are shown at the top and the bottom, respectively. The conserved residues are highlighted in red boxes outlined in blue. This figure was created by using the program ESPript (10). (b) Stereo Cα superposition of VP26 (green) and VP28 (blue). The superposition was generated using the program O (18), using the conserved residues as the starting point. The RMSD between VP26 and VP28 is 2.6 Å for 144 Cα atoms. This figure was prepared using the program MOLSCRIPT (19). (c) Simulated annealing Fo-Fc omit map showing the conserved region of VP26. (d) The same map as used in panel c applied to VP28. All the residues shown in the figure as well as all the atoms within 3 Å of these residues were omitted prior to refinement and map calculation. The map was contoured at a level of 2σ for VP26 and 2.5σ for VP28. This figure was prepared using the program BOBSCRIPT (8).
