    Most cases of cystic fibrosis (CF), a common inherited disease of epithelial cell origin, are caused by the deletion of Phe508 located in the first nucleotide-binding domain (NBF1) of the protein called CFTR (cystic fibrosis transmembrane conductance regulator). To gain greater insight into the structure within the Phe508 region of the wild-type protein and the change in structure that occurs when this residue is deleted, we conducted nuclear magnetic resonance (NMR) studies on representative synthetic 26 and 25 amino acid peptide segments. 2D 1H NMR studies at 600 MHz of the 26-residue peptide consisting of Met498 to Ala523 in 10% DMSO, pH 4.0, at 25 degrees C show a continuous but labile helix from Gly500 to Lys522, based on both NH-NH(i,i+1) and alphaH-NH(i,i+1) NOEs. Phe508 within this helix shows only short-range (i,
