Proteins having similar three dimensional structures have similar functions. It is proposed to find the structurally similar proteins through graph similarity. Graph theoretical concepts are used to analyze protein similarity using contact maps. Protein graph is derived from its contact map. In this paper, clustering coefficient of nodes is used to find the structurally similar/dissimilar proteins. High positive correlation is observed between the clustering coefficient of similar proteins 2RM2 and 2RR1 and no correlation between dissimilar proteins 2RM2, 5JXl and 2RR1, 5JXL.
