NMR Refinement
MethodDetailsSoftware
200 structures were generated in CYANA. The 100 structures with lowest energy were further refined in AMBER7. The 20 lowest energy structures were finally selected.A total of 4689 restraints were used. Included are 1630 ambiguous and 2640 unambiguous NOE-derived distances, 100 hydrogen bond restraints, 190 backbone dihedral angles, 32 side-chain chi1 and 97 1H-15N residual dipolar couplings values.XWINNMR
