Method	Details	Software
simulated annealing	THE STRUCTURES ARE BASED ON A TOTAL OF 1157 CONFORMATIONALLY-RESTRICTING NOE-DERIVED DISTANCE RESTRAINTS, 177 DIHEDRAL ANGLE RESTRAINTS, AND 32 HYDROGEN BOND RESTRAINTS. (14.4 CONSTRAINTS PER RESIDUE; 6.1 LONG-RANGE RESTRAINTS PER RESIDUE). STRUCTURE DETERMINATION WAS PERFORMED ITERATIVELY USING AUTOSTRUCTURE (XPLOR). THE UNSTRUCTURED 8 RESIDUE C-TERMINAL TAG (LEHHHHHH) WAS INCLUDED IN THE STRUCTURE CALCULATIONS BUT IS OMITTED FROM THIS DEPOSITION.	X-PLOR

Additional NMR Experimental Information

Details

THE STRUCTURE WAS DETERMINED USING TRIPLE-RESONANCE NMR SPECTROSCOPY. AUTOMATIC BACKBONE RESONANCE ASSIGNMENTS WERE MADE USING AUTOASSIGN. MANUAL SIDE CHAIN ASSIGNMENTS. AUTOMATIC NOESY ASSIGNMENTS AS WELL AS DISTANCE AND HYDROGEN BOND RESTRAINTS WERE DETERMINED USING AUTOSTRUCTURE. DIHEDRAL ANGLE RESTRAINTS WERE DETERMINED USING HYPER AND TALOS. BACKBONE DIHEDRAL ANGLES FOR RESIDUES 1, 13-20, 26-27, 39-40, 47-51, 54, 63-66 AND 73-79 ARE NOT WELL-DEFINED [S(PHI) + S(PSI) < 1.8] IN THIS SOLUTION NMR STRUCTURE.
