Details The structures are based on a total of 2 phi angle and 57 NOE-derived distance constraints. 1000 high-temperature steps were used (15 ps) up to a final temperature of 50000 K then 1000 cooling steps (250 K, 15 ps) were applied. Finally, 10 cycles of 200 minimization steps were performed. A repel constant value of 0.8 was used
