| Details | THE INITIAL STRUCTURES WERE OBTAINED USING CYANA AUTOMATIC CALCULATION, BASED ON CHEMICAL SHIFT LISTS FROM SEQUENCE-SPECIFIC RESONANCE ASSIGNMENT AND NOES FROM 15N AND 13C-EDITED 3D-NOESY SPECTRA. THROUGHOUT ALL CALCULATIONS,121 BACKBONE TORSION ANGLE CONSTRAINTS DERIVED FROM TALOS, WERE EMPLOYED. CNS WAS USED FOR FURTHER REFINEMENT, USING THE DISTANCE AND DIHEDRAL ANGLE CONSTRAINTS OBTAINED FROM THE FINAL CYCLE OF THE CYANA CALCULATION, AND SEVERAL ADDITIONAL NOE CONSTRAINTS FROM MANUAL CHECKING OF THE 3D NOESY DATA. IN TOTAL, 2401 EXPERIMENTAL NOE-RESTRAINTS (~20 PER RESIDUE) WERE EMPLOYED. |
