| Details | This structure was generated from the five-fold symmetry of PDB entry 1IFI, which has the symmetry that relates one pentamer to the next. This one has had the sidechains added using the program SCWRL. The structure was determined by solid state nuclear magnetic resonance using the whole virus in suspension. A model of a section of the virion capsid was built with 20 copies of the protein arranged in agreement with previous studies by fiber diffraction (Marvin et al., J. Mol. Biol. 235, 260286 (1994)). |
