Amino acid polarity and asymmetry of net gains and losses. A. Correlation between relative net gain (D) and difference in polarity (Destination-Source) for 190 pair of amino acids. B. Net decrease of mean amino acid polarity due to substitutions in proteins of different molecular functions. C. Net decrease of mean amino acid polarity due to substitutions in proteins of different cellular localization.
