NMR Refinement
Method	Details	Software
simulated annealing	In the first stage, high temperature Cartesian dynamics was performed at 1000 K with a time step of 0.005 ps, for 20,000 steps, using the Verlet integrator. During the second cooling phase of the protocol, the temperature was reduced from 1000 K to 100 K in steps of 50 K, with a time step of 5 fs, over 40,000 steps during which the relative weighting of non-bonded energy terms were increased from 10% of their default values to their force field default. These initial structures were then refined with another 10000 cooling step	X-PLOR NIH
