A new spatial representation of amino acid residues in globular proteins.
For the globular proteins with known three-dimensional structures, an ellipsoid model of each protein was constructed with least volume and its dimensions were derived. The spatial arrangements were made for the C alpha and side chain atoms of that protein within that ellipsoid. This new spatial representation shows the residue position from the centroid, as well as the depth from the surface. The average spatial parameters were then calculated. The correlations between these new spatial parameters and the existing parameters of the amino acid residues were then derived.
