Novel 2-D graphical representation of proteins

We have outlined novel highly compact graphical representation for proteins, which offers graphical and numerical characterization of individual proteins. Protein representations are constructed in the interior of a unit 'magic' circle, on the circumference of which at equal distances are positioned 20 amino acids. Graphical representation of proteins is obtained by starting in the center of the circle following amino acid sequence by moving half way towards the corresponding amino acid - analogously to the scheme of Jeffrey for graphical representation of DNA. Graphical form of depicted protein depends on ordering on amino acids, however, the relative variations between protein sequences remain to large extent independent of the ordering of proteins along the periphery of unit circle.
