Automated NOE assignment,Torsion angle dynamics, Cartesian simulated annealing. | The structure was calculated automated NOE assignment and structure calculation using ARIA/CNS. Manual NOE assignments were added between cycles of automated assignment. The final structures were refined in a shell of explicit solvent. Data consisted of: 1230 unique NOE restaints; 44 phi restraints (3JHNHA scalar couplings, direct refinement against couplings); 41 1JHN residual dipolar couplings. Final ensemble was refined in explicit water. | XwinNMR |
