Additional NMR Experimental Information
Details	THE SOLUTION STRUCTURES THE P25 (25 AMINO ACID FRAGMENT FROM THE CFTR NBD-1) PEPTIDE WERE DETERMINED IN 43% TRIFLUROETHANOL AND H2O BY HOMONUCLEAR 1H NMR SPECTROSCOPY PREFORMED ON A 600 MHZ SPECTROMETER.. NOESY SPECTRA AT 100,200 AND 300 MS MIXING TIMES, TOCSY SPECTRUM AT 65 MS, AND COSY SPECTRUM WERE COLLECTED AND USED TO ASSIGN THE 1H RESONANCES AND NOES TO DETERMINE THE SOLUTION STRUCTURE
