A statistical analysis is made of the distribution into alpha-helical and non-alpha-helical regions of the various dipeptide types appearing in a sample of seven proteins of known sequence and structure. By considering as a group all dipeptide types occurring at a given location relative to the reported helix-coil boundaries and examining the percentage of cases in which these appear in non-alpha-helical regions throughout the protein sample, we find a sharp change in the nature of the observed… CONTINUE READING
