| distance geometry, simulated annealing | The structures are based on a total of 1229 restraints, 1034 are NOE-derived distance constraints, 127 dihedral angle restraints, 68 distance restraints from hydrogen bonds. There are no constraints for the two peptidic segments: E59-Q61 and R76-T87. | Gifa |
