NMR Refinement
Method	Details	Software
SIMULATING ANNEALING	Structures are based on a total of 1383 nonredundant distance NOE restraints, 61 dihedral angle restraints and 24 paired distance restraints for hydrogen bonds.	X-PLOR

NMR Ensemble Information
Conformer Selection Criteria	structures with the least restraint violations,structures with the lowest energy
Conformers Calculated Total Number	50
Conformers Submitted Total Number	30
Representative Model	1 (lowest energy)

Additional NMR Experimental Information
Details	This Structure was determined using a combination of 2D and 3D NMR spectra. THE 30 STRUCTURES ARE ALIGNED OVER ALL BACKBONE ATOMS FOR RESIDUES 10-25 AND 32-43. MODEL 1 IS THE MINIMUM ENERGY AND REFERENCE STRUCTURE FOR THE OTHER 29 STRUCTURES.
