RDC directed fragment assemblyRDCs were used in the initial assembly of four fragments. RDCs from two media were used to set relative orientations of the fragments. Translational relationships of fragments were dictated by sequence connectivities and long-range NOEs. The assembled structure was minimized using a molecular force field and RDC error function. A total of 486 restraints were used: 380 residual dipolar coupling restraints, 85 NOE restraints (of which 64 were sequential, 11 short-range and 10 long-range), and 21 dihedral restraints. All sidechain atoms beyond CB are missing.NMRPipe
