SOLID-STATE NMR SPECTROSCOPY
The first five N-terminal residues of the coat protein undergo
isotropic movements at room temperature and structural parameters
cannot be resolved.

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)).
