The 80 structures of lowest penalty function were refined using the Sander module of AMBER (v6.0). The calculation employed 79 distance restraints, 12 dihedral angle restraints and 13 chemical shift restraints. The 20 structures of lowest violation energy were chosen to represent the structure. There are no violations of the input restraints > 0.1 A or 2 degrees. The rms. difference between calculation and observed chemical shifts is 0.09 ppm. 79% of the backbone geometries are in the most favourable region of the Ramachandran plot. The backbone heavy atom rmsd from the mean structure is 0.39+/-0.08 A.
