The simulated annealing protocol using the pairwise generalized Born model was as follows: the temperature of the system was kept constant at 600 K during the first 5 ps, cooled down slowly to 100 K between 5-18 ps, and cooled down to 0 K for the last 7 ps. The protocol was repeated 50 times to obtain an NMR ensemble with the 10 lowest RMSD structures. The structure with the lowest RMSD of the ensemble was put back into MARDIGRAS for a second and third cycle of NOE calibration and structure calculations.
