NMR Refinement
Method simulated, annealing molecular dynamics, matrix relaxation
Details the structures are based on a total of 280 NOE-derived distance constraints obtained from a complete relaxation matrix refinement. The structures were calculated by using restrained molecular dynamics with explicit solvent, and applying the particle mesh Ewald method.
