On the basis of three kinds of indices of physicochemical properties of twenty amino acids, a novel 3D graphical representation of protein sequences is presented. Then, the improved cumulative distance of the 3D graphical representations is defined in order to compare the proteins for...

Based on three physicochemical properties of amino acid side chains, we proposed a novel unique 3D graphical representation of protein sequences. Then, we constructed two vectors of three components as mathematical objects to characterize protein sequences numerically. The...
