NMR Refinement
Method	Details	Software
simulated annealing	STRUCTURES WERE REFINED WITH MULTIPLE ROUNDS OF SIMULATED ANNEALING WITH THE ADDITION OF NEW NOES AND CORRECTION OF UNAMBIGUOUS NOES. PHI ANGLES WERE ONLY ADDED WHEN THEY AGREED WITH THE PURELY NOE DRIVEN CONVERGENCE OF THAT ANGLE IN INITIAL STRUCTURE CALCULATIONS. OTHER REFINEMENT INFORMATION CAN BE FOUND IN THE JRNL CITATION ABOVE.	X-PLOR

NMR Ensemble Information
Conformer Selection Criteria	STRUCTURES WERE SELECTED WITH NO VIOLATIONS GREATER THAN 0.3 ANGSTROMS OR DIHEDRAL ANGLES GREATER THAN 0.5 ANGSTROMS AND GOOD COVALENT GEOMETRY.
Conformers Calculated Total Number	40
Conformers Submitted Total Number	32
