NMR Refinement
Method Torsion angle molecular dynamics. Refinement and energy minimization in a water shell using Cartesian dynamics and powell minimization.
Details Initial structures were generated by torsion angle dynamics. These were then refined and minimized in a water shell using Cartesian dynamics and restrained powell minimization according to ARIA and CNS protocols.
NMR Ensemble Information
Conformer Selection Criteria structures with the least restraint violations, structures with the lowest energy
Conformers Calculated Total Number 50
Conformers Submitted Total Number 20
Representative Model Choice Rationale
1 lowest energy
