title: The conformation of bombesin in solution as determined by two-dimensional 1H-NMR techniques.
abstract: The 1H nuclear magnetic resonance spectrum of the tetradecapeptide, bombesin, has been assigned in (2H6)dimethyl sulphoxide solution and aqueous solution using two-dimensional techniques. The chemical shifts in both solvents indicate that the molecule has little secondary structure and adopts a random coil conformation. A comparison is made between the spectra of various smaller bombesin fragments and the intact polypeptide.
