restrained molecular dynamics | The structures were detemined on the basis of 149 NOE distance restraints and 15 dihedral angle restraints. The resulting ensemble had no restraint violations greater than 0.07 Angstroms or 1.4 deg. The mean restraint violation energy was 0.17+/- 0.06 kcal/mol. | DGII |
