NMR Refinement
Method distance geometry and restrained molecular dynamics
Details 100 distance geometry structures were calculated. The 80 structures of lowest penalty function were further refined using restrained molecular dynamics. The 20 structures of lowest restraint violation energy were used to describe the structure. 61 distance and 21 dihedral angle restraints were used. The final ensemble has no distance violations greater than 0.1 A and no dihedral angle vioaltions greater than 1 degree. 95% of the residues are in the most favourable region of the Ramachandran plot. The mean backbone atom rmsd to the mean structure is 0.29+/-0.05 A.
