From: Metabolic network alignment in large scale by network compression
Shift of out-degree distributions from power law to uniform. Changes in the out-degree distributions of ten organism-wide metabolic networks with increasing levels of compression. We calculate the frequencies of each out-degree in the range [2,40] for c ∈ {0, 1, 2, 3, 4} and plot them together for each of the ten organisms in our dataset. Out-degree distributions for organism-wide metabolic networks of (a) Arabidopsis thaliana (thale cress), (b) Caenorhabditis elegans (nematode), (c) Drosophila melanogaster (fruit fly), (d) Escherichia coli K-12 MG1655, (e) Homo sapiens (human), (f) Mus musculus (mouse), (g) Pseudomonas aeruginosa PAO1, (h) Rattus norvegicus (rat), (i) Staphylococcus aureus COL (MRSA), (j) Saccharomyces cerevisiae (budding yeast).
