| distance geometry, molecular dynamics | The structures are based on 91 distance restraints and 26 dihedral angle restraints. None of the final structures have violations > 0.07A or 1.0 degrees. The mean rmsd to the mean coordinates for heavy atoms of residues Cys3 to Tyr15 is 0.31+/-0.06 A. | DGII |
