NMR Refinement
Method	Details	Software
molecular dynamics	AUTOMATED METHODS WERE USED FOR BACKBONE CHEMICAL SHIFT ASSIGNMENT AND ITERATIVE NOE REFINEMENT. FINAL STRUCTURES WERE OBTAINED BY MOLECULAR DYNAMICS IN EXPLICIT SOLVENT. STRUCTURES ARE BASED ON A TOTAL OF 1353 NOE CONSTRAINTS (401 INTRA, 210 SEQUENTIAL, 255 MEDIUM, AND 487 LONG RANGE) AND 122 PHI AND PSI DIHEDRAL ANGLE CONSTRAINTS.	NMRPipe
