NMR Refinement
Method Details Software
simulated annealing, torsion angle dynamics An ensemble of 200 structures was generated by simulated annealing under a set of 218 NOE-derived upper distance restraints and 11 3JHHA coupling-derived phi angle restraints. 20 lowest energy structures were refined further by energy minimization using TINKER 6.0. 1
