NMR Refinement
Method	Details	Software
DISTANCE GEOMETRY, SIMULATED ANNEALING, MOLECULAR DYNAMICS	THE STRUCTURES WERE GENERATED USING 564 INTER-PROTON DISTANCE RESTRAINTS DERIVED FROM 230 INTRA-RESIDUAL, 141 SEQUENTIAL, 108 MEDIUM RANGE AND 85 LONG RANGE NOE INTENSITIES. THESE DISTANCE RESTRAINTS WERE SUPPLEMENTED WITH 17 BACKBONE AND 7 SIDE-CHAIN DIHEDRAL ANGLE RESTRAINTS FROM SPIN-SPIN COUPLING CONSTANTS.	XwinNMR
