NMR Ensemble Information
Conformer Selection Criteria The submitted conformer models are the 20 structures with the lowest energy.
Conformers Calculated Total Number 50
Conformers Submitted Total Number 20
Representative Model Choice Rationale
1 closest to the average
Additional NMR Experimental Information
1 The sample was a purified single peptide component but on dissolution displayed evidence of multiple conformations (manifest by peaks "brothering" in the N-terminal region). The structures shown are for the major solution conformer.
