NMR Refinement
Method	Details	Software
AUTOMATED METHODS WERE USED FOR BACKBONE CHEMICAL SHIFT ASSIGNMENT AND ITERATIVE NOE REFINEMENT. FINAL STRUCTURES WERE OBTAINED BY MOLECULAR DYNAMICS IN EXPLICIT SOLVENT.	RR-CSP STRUCTURES ARE BASED ON A TOTAL OF 1813 NOE CONSTRAINTS (1123 INTRA, 298 SEQUENTIAL, 86 MEDIUM, 306 LONG RANGE) AND 120 PHI AND PSI DIHEDRAL ANGLE CONSTRAINTS.	Xplor-NIH
