NMR Refinement
distance geometry/simulated annealingThe structures are generated by 4D simulated annealing with EMBOSS, based on a total of 916 experimental restraints, 852 are NOE-derived distance restraints, 36 hydrogen restraints and 28 dihedral restraints. 25 out of 100 structures which have the lowest violation and a low energies were selected for the final set.EMBOSS
