Method	Details	Software
Monte Carlo optimization of ensemble members	A 10,000-MEMBER SET OF STRUCTURES WAS GENERATED USING ROSETTA AND BACKRUB CONFORMATIONAL SAMPLING. THE 50-MEMBER ENSEMBLE PRESENTED HERE WAS OPTIMIZED BY SELECTING STRUCTURES FROM THIS SET THAT MAXIMIZE AGREEMENT WITH THE RESIDUAL DIPOLAR COUPLINGS. SEVERAL OF THE STRUCTURES IN ENSEMBLE ARE IDENTICAL AS CHOSEN BY THE OPTIMIZATION ALGORITHM.	Rosetta
