A Toolbox Model of Evolution of Metabolic Pathways on Networks of Arbitrary Topology

vs. 
of toolbox model with branched pathways and multi-substrate reactions.
The scaling between the number of regulated pathways (leaves), 
and the number of metabolites, 
, in metabolic networks generated by the toolbox model with branched pathways and multi-substrate reactions. Solid line with slope 2.0+/−0.1 is the best fit to the data. Error bars reflect the standard deviation of 
at a given value of 
in 9 realizations of the model (see he section “Error analysis of the toolbox model” of Text S1 for our estimation methods and error analysis).
