NMR Refinement
Method Hybrid distance geometry/simulated annealing followed by restrained molecular dynamics.
Details Structures were calculated based on a total of 109 distance and 16 dihedral angle restraints. The final ensemble of 20 models has no distance or dihedral angle restraint violations greater than 0.1 angstrom or 2 degrees, respectively.

Additional NMR Experimental Information
1 3JHNHa were obtained by fitting Lorentzian lines to the antiphase doublets of HN-Ha peaks in a 2QF-COSY spectrum processed to high digital resolution in F2. 3JHNHa for Gly8 and Gly11 were obtained from analysis of the COSY-35 spectrum acquired in H2O. 3JHaHb were extracted from a COSY-35 spectrum acquired in D2O.
