Graphical representation of DNA sequences by Chaos Game Representation (CGR) reveals the intrinsic structures of gene sequences. Although CGR of DNA sequences has been studied extensively, there are only a few reports of similar studies on protein sequences. We have applied a novel method of CGR for protein sequences and found that the intrinsic structures of different families of protein sequences were elucidated uniquely. CGRs of different families of protein sequences depicted “Sierpinski triangle” type of fractal objects possessing self-similar structure. The novel graphical representation of protein sequences and the results will be presented.
