molecular dynamics matrix relaxation | The structures are based on a total of 311 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 | DYANA |
