NMR Refinement
Method Simulated annealing using both torsion angle and Cartesian dynamics.
Details Structure was calculated using torsion angle dynamics within CNS and subsequently refined and energy minimised in a water shell using Cartesian dynamics in CNS according to protocols by Linge and Nilges (ARIA).
