Query: Quantifying randomness in protein-protein interaction networks of
  different species: A random matrix approach   We analyze protein-protein interaction networks for six different species
under the framework of random matrix theory. Nearest neighbor spacing
distribution of the eigenvalues of adjacency matrices of the largest connected
part of these networks emulate universal Gaussian orthogonal statistics of
random matrix theory. We demonstrate that spectral rigidity, which quantifies
long range correlations in eigenvalues, for all protein-protein interaction
networks follow random matrix prediction up to certain ranges indicating
randomness in interactions. After this range, deviation from the universality
evinces underlying structural features in network.
