Additional NMR Experimental Information
1 Distance restraints were determined using NOESY build-up curves. The coupling constants were determined using phase sensitive COSY and TOCSY experiments. E threshold cutoff and deltaE allowance for MEDUSA were 600 and 100 kCal/mol respectively Clustering was performed with a cutoff of 1.0Angstrom A conformer was defined as different if either phi or psi angle for at least one aminoacid was differing by >15 degrees
