A Toolbox Model of Evolution of Metabolic Pathways on Networks of Arbitrary Topology
Figure 2
is the number of leaves in an organism-specific metabolic network and equal to the number of transcriptional regulators of corresponding nutrient-utilizing pathways, while
is the total number of nodes/metabolites in this netowrk. The data are generated by the toolbox model on critical universal network with sizes around 2000. Solid line
