A 3-D Graphical Method Applied to The Similarities of Protein Sequences

Based on the selected chemical and physical properties of amino acids, a dynamic 3-D graphical representation of protein sequences is outlined. We introduce the numerical characterization of protein graphs as descriptors to analyze and compare the nine ND5 proteins, and the results consist with the known fact of evolution. The graph of protein sequences have good visibility, the approach is simple, convenient, and fast.
