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	HOMODIMER STRUCTURES ARE BASED ON A TOTAL OF 4063 NOE CONSTRAINTS ( 843 INTRA, 818 SEQUENTIAL, 1029 MEDIUM, 750 INTRAMONOMER LONG RANGE AND 623 INTERMONOMER NOE CONSTRAINTS) AND 264 PHI AND PSI DIHEDRAL ANGLE CONSTRAINTS. CONSTRAINTS WERE ASSIGNED AND VALIDATED IN ONE MONOMER AND THEN DUPLICATED TO GENERATE A SYMMETRY RELATED CONSTRAINTS IN THE SECOND MONOMER. CONSTRAINT TOTALS LISTED ABOVE INCLUDE CONSTRAINTS FROM BOTH MONOMERS.	XPLOR-NIH
