NMR Refinement
Method full matrix relaxation analysis of NOE, random error analysis of NOE, simulated annealing using torsion angle dynamics, simulated annealing using Metropolis Monte Carlo, restrained minimization
Details The NMR refinement was based on a total of 434 interproton distance restraints (16.1 per residue). The restraints include 353 MARDIGRAS-derived quantitative restraints for nonexchangeable protons (with an average flat-well width of 1.51 angstroms), 63 qualitative restraints for exchangeable protons, and 18 H-bond restraints for Watson-Crick GC pairs.
