NMR Refinement Method Details Software simulated annealing, molecular dynamics, torsion angle dynamics Structures were initially calculated using DYANA.
CYANA 2.0 was used for automated data analysis to obtain additional NOE constraints. The structures were then refined against residual dipolar couplings using XPLOR-NIH and a water-refinement protocol. NMRPipe
