Fig. 7From: Resource constrained flux balance analysis predicts selective pressure on the global structure of metabolic networksStructural parameter distributions of Reconstructed networks. Distribution of different structural parameters of 143 different species classified in two groups of facultative and non-facultative organisms with size of 59 and 84 species, respectively. The distributions of a number of genes used in reconstructed metabolic model, b number of input metabolites (transporters), c average in- or out-degree of the networks considering directed links, d average of shortest path between an input metabolite and each of biomass ingredients, e the average of distances between input metabolites and f fraction of essential reactions. p-values are calculated by the Kruskal-Wallis testBack to article page
