Additional NMR Experimental Information
1 The structure was determined by double and triple resonance heteronuclear NMR spectroscopy techniques. There is evidence of substantial conformational exchange in sections of the chain that severely limit the precision of the structure in these regions of the molecule. Specifically, conformational exchange occurs in the regions D19-M33 and L55-S63.
