NMR Refinement
Method Details Software
Simulated annealing using cartesion and torsion angle dynamics NOE assignments, distance restraint calibration, and initial structures were made using ARIA 1.2 with 370 NOE volumes. Final structure refinement was done using CNS 1.1 with 262 unambiguous distance restraints, 13 H-bonds, 48 HNHA coupling constants, and 59 NH residual dipolar couplings. 1
