NMR Refinement
Method simulated annealing
Details Structure determination of this symmetric homodimer was performed iteratively using CYANA 3.02. The 20 structures out of 100 with lowest target function were further refined by restrained molecular dynamics/energy minimization in explicit water using CNS 1.3. Residual dipolar couplings and backbone dihedral angle constraints for the ordered regions were applied at all stages of the structure determination
