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 1295 NOE CONSTRAINTS ( 320 INTRA, 370 SEQUENTIAL, 104 MEDIUM, 420 LONG RANGE and 81 INTERMONOMER CONSTRAINTS) AND 131 PHI AND PSI DIHEDRAL ANGLE CONSTRAINTS. CONSTRAINT WERE IN ONE ASSIGNED AND VALIDATED IN ONE MONOMER AND THEN DUPLICATED TO GENERATE A SYMMETRY RELATED CONSTRAINT IN THE SECOND MONOMER. CONSTRAINT TOTALS LISTED ABOVE INCLUDE CONSTRAINTS FROM BOTH MONOMERS.	Xplor-NIH
