Degree distributions of the bipartite network, for (a) complexes and (b) proteins. Here, the degree in (a) corresponds to the number of component proteins for each complex, and the degree in (b) corresponds to the number of complexes in which a protein participates as a component. The blue squares correspond to the cumulative degree distribution P(k) = ∑k′ k p(k′), and the pink lines and gray curves are the best exponential and power-law fittings, respectively.
