NMR Refinement
Method substructure distance geometry, full structure distance geometry-simulated annealing; torsion angle dynamics
Details structures are based on a total of 1583 constraints, 1168 are NOE distance, 138 are dihedredral angle, 58 are 3JHNHa coupling constant, 219 are residual dipolar couplings,
NMR Ensemble Information
Conformer Selection Criteria structures with acceptable covalent geometry, structures with favorable non-bond energy, structures with the least restraint violations, structures with the lowest energy
Conformers Calculated Total Number 50
Conformers Submitted Total Number 10
Representative Model Choice Rationale
1 fewest violations, lowest energy
Additional NMR Experimental Information
1 This structure was determined by refining simultaneously against NOE, J-coupling, dihedral angle, and residual dipolar coupling constraints
