Interaction between water and polar groups of the helix backbone: An important determinant of helix propensities
We report an enthalpic factor involved in determining helix propensities of nonpolar amino acids. Thermal unfolding curves of the five 13-residue peptides, Ac-KA(4)XA(4)KGY-NH(2) (X = Ala, Leu, Ile, Val, Gly), have been measured by using CD in water/trifluoroethanol (TFE) mixtures. The peptide helix...
