NMR Refinement
Method	Details	Software
Torsion angle dynamics. Refinement and energy minimization in a water shell using Cartesian dynamics and powell minimization.	Initial structures were generated by torsion angle dynamics. These were then refined and minimized in a water shell using Cartesian dynamics and restrained powell minimization according to ARIA and CNS protocols.	XwinNMR

Conformer Selection Criteria	structures with the least restraint violations, structures with the lowest energy
Conformers Calculated Total Number	50
Conformers Submitted Total Number	20
Representative Model	1 (lowest energy)

Additional NMR Experimental Information
Details	This structure was determined using standard 2D homonuclear techniques.
