Details The structures are based on a total of 1047 NOE derived, and 55 dihedral constraints. There are no long-range NOEs observed for the first 8 residues which are disordered.
NMR Ensemble Information
Conformer Selection Criteria structures with lowest energy and no restraint violations with phi psi angles in allowed regions
Conformers Calculated Total Number 100
Conformers Submitted Total Number 20
Representative Model Choice Rationale
1 lowest energy
Additional NMR Experimental Information
