NMR Refinement
Method	Details	Software
Initail structure was calculated with Torsion Angle Dynamics and refined with simulated annealing and included a term for explicit solvent in the refinement protocol.	The structures were based on a total of 2630 restraints, 2198 conformationally restricting NOEs, 232 dihedral angle constraints and 200 hydrogen bond constraints	AutoStructure

NMR Ensemble Information
Conformer Selection Criteria	10 structures from initial DYANA calcultions with the lowest target functions were refined using CNS. The structures back calculated data agree with experimental NOESY spectra. The structures have acceptable covalent geometry, favorable non-bond energy, the lowest energy and the fewest restraint violations.
Conformers Calculated Total Number	196
Conformers Submitted Total Number	10
Representative Model	1 (lowest energy)
