Figure 2.

Effects of paralog removal on the metabolic network. The main figure reports the connectivity distributions P(k) for metabolites in the empirical network (red squares) and in 1000 collapsed networks (blue dots). The two distributions are very similar. In the inset a boxplot reporting the fraction of metabolites of the empirical network present in the 1000 collapsed networks is shown. Dashed lines indicate the mean, the upper and lower box margins correspond to the standard deviation (SD), and whiskers indicate two SD.
