Topological properties of PPI network. The degree distribution (p(k)), clustering coefficient (C(k)), average neighborhood connectivity ($C_{\mathrm{N}}$(k)), betweenness centrality ($C_{\mathrm{B}}$(k)), closeness centrality ($C_{\mathrm{C}}$(k)) and topological coefficient ($T_{\mathrm{C}}$(k)) as a function of k. The power law with exponent $\alpha$, $\mathrm{\beta }$, $\mathrm{\gamma }$, Φ, $\mathrm{\mu }$ and $\mathrm{\epsilon }$ for p(k), c(k), $C_{\mathrm{N}}$(k), $C_{\mathrm{B}}$(k), $C_{\mathrm{C}}$(k) and $T_{\mathrm{C}}$(k) respectively
