torsion angle dynamics, simulated annealing | The input for the final structure calculation of N-domain protein consisted of 1279 upper limit distance restraints and 358 dihedral angle restraints. 185 of the dihedral angle restraints reflected coupling constant information, while 173 of them had been derived by HABAS from NOE and steric restraints alone. | XwinNMR |
