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 SOLVEN	STRUCTURES ARE BASED ON A TOTAL OF 894 NOE CONSTRAINTS ( 366 INTRA, 186 SEQUENTIAL, 133 MEDIUM and 209 LONG RANGE CONSTRAINTS) AND 97 PHI AND PSI DIHEDRAL ANGLE CONSTRAINTS.
