Torsion angle dynamics followed by molecular dynamics refinement in explicit water solvent | The initial structures were computed using the auto noeassign feature of CYANA 2.1; 1503 NOE distance restraints were assigned, and 147 dihedral angle restraints were used in the calculation. The 20 best CYANA structures were refined in explicit solvent using ARIA 2.0a with the 1506 NOE distance restraints, 147 dihedral angle restraints, 42 H-bond restraints, and 48 residual dipolar coupling restraints. | VNMR |
