Oligopeptides' frequencies in the classification of proteins' primary structures

  title={Oligopeptides' frequencies in the classification of proteins' primary structures},
  author={Paolo Sirabella and Alessandro Giuliani and Alfredo Colosimo},
This paper reports about an approach to the classification of proteins’ primary structures taking advantage of the Self Organizing Maps algorithm and of a numerical coding of the aminoacids based upon their physicochemical properties. Hydrophobicity, volume, surface area, hydrophilicity, bulkiness, refractivity and polarity were subjected to a Principal Component Analysis and the first two principal components, explaining 84.8 % of the total observed variability, were used to cluster the… CONTINUE READING
