NMR Refinement
Method torsion angle dynamics, molecular dynamics, energy minimization.
Details 50 initial random structures were generated using simulated annealing in DYANA software, followed using the DISCOVER module of MSI software, by 500 steps restrained minimization, 35 ps MD in vacuo at 300K, 200ps MD under NMR restraints and 750ps conjugated gradient EM.

Additional NMR Experimental Information
1 This structure was determined using standard 2D homonuclear techniques. NOESY experiments were recorded with mixing times from 80ms to 800ms in order to determined the best conditions to avoid spin diffusion.
