Figure 3.
Topological features of the predicted protein–protein interaction network in E. coli K12. (A) The degree distribution clearly shows that the network follows scale-free properties. (B) The distribution of the clustering coefficient shows that the network is not hierarchical. Both the axes represent the respective logarithmic values. (C) Distribution of the shortest path between pairs of proteins in the predicted network. (D) The null network possesses a Gaussian degree distribution as observed in the log–log plot.
