Venn diagrams showing the overlap between the reactions (a) and metabolites (b) present in the reconstructed GSMMs of Methylocella silvestris, Methylocystis parvus and Methylocystis hirsuta. The plot (c) shows the logarithm of the metabolite connectivity (k, the number of reactions in which a metabolite takes part) versus the logarithm of the number (n) of metabolites with connectivity k. The plot shows a typical scale-free topology with a negative slope of 2.5 and an overrepresentation of highly connected metabolites such as ATP and redox co-factors
