This standard torsion angle based simulating annealing protocol with all constraints applied simultaneously is combined with cycles of redundant dihedral angle constraints (REDAC; Guntert and Wuthrich, 1991). Several cycles of this combined refinement protocol, which eliminates violations and progressively reduces target function values while improving local and overall quality, were used to generate the final converged structures. Out of an ensemble of 100 converged structures generated, the 20 best (lowest CYANA target function during refinement) structures were selected.
