NMR Ensemble Information
Conformer Selection Criteria The submitted conformer models are the 20 structures with the lowest energy from 122 acceptable structures which were from 400 total calculated structures and had no restraint violations. The best representative conformer is the lowest potential energy structure of the ensemble.
Conformers Calculated Total Number 400
Conformers Submitted Total Number 20
Representative Model Choice Rationale
1 lowest energy
