Position dependence of non-polar amino acid intrinsic helical propensities1

We have interpreted the results from these experiments with the model of the helix/coil transition (AGADIR), that indicates that the intrinsic helical propensity is position dependent. Gly, Val and Ile are more favorable at the first turn than in the middle of the -helix, while for Leu and Met we observe the opposite behavior.
