Method Torsion angle dynamics (DYANA) for generation of initial structures; Structure-mediated assignment of ambiguous experimental restraints (SANE); Iteration between DYANA and SANE; Simulated Annealing and Energy Minimization in AMBER using full restraint set.
Details Structures are based upon 2232 NOE-derived distance restraints (365 long-range, 379 medium-range, 403 sequential, 1085 intraresidue, and 426 ambiguous), 155 torsion angle restraints, and 47 stereospecific assignments.
