The primary protein sequence is read as consecutive order pairs serially from first amino acid to the end of sequence, and each order pair is nothing but a connected edge between the two nodes where nodes in the graph are involved with different chemical groups of amino acids. Our method of phylogenetic tree formation used the dissimilarity matrix which is obtained for every pair of sequence on the basis of chemical group specific score of amino acids. Based on the phylogenetic tree of five members, we find that the PpcA and PpcD, PpcB and PpcE are mostly closed with regards to the frequency of amino acids of respective eight chemical groups.	./cache/cord-002473-2kpxhzbe.txt	./txt/cord-002473-2kpxhzbe.txt
