NMR Refinement
Method	Details	Software
torsion angle dynamics	THE STRUCTURE WAS CALCULATED USING 1177 NOE RESTRAINTS AND 75 DIHEDRAL ANGLE RESTRAINTS; RESIDUES 1-3 AND 89-94 WERE NOT INCLUDED IN THE REFINED MODEL BECAUSE OF A LACK OF RESTRAINTS IN THESE PRESUMABLY UNSTRUCTURED REGIONS OF THE PROTEIN.	DYANA

NMR Ensemble Information
Conformer Selection Criteria	structures with acceptable covalent geometry, structures with the least restraint violations, target function
Conformers Calculated Total Number	200
Conformers Submitted Total Number	20
Representative Model	1 (fewest violations, lowest energy)
