NMR structure calculation is performed using CYANA via the UNIO interface as described in Supplementary Material. The structure statistics are obtained from the ensemble of 20 models generated at the end of 7 successive CYANA runs. N- and C-terminal residues with a low density of NOEs are excluded from RMSD calculations. RDC data were used at a late stage of refinement for further optimization of the models using XPLOR-NIH (Supplementary Material). Axiality (DP) and rhombicity (|) are calculated from RDC data and the refined structure by XPLOR-NIH.
