From: The use of genome-scale metabolic network reconstruction to predict fluxes and equilibrium composition of N-fixing versus C-fixing cells in a diazotrophic cyanobacterium, Trichodesmium erythraeum

Fig. 2

Predicted central metabolic fluxes for (a) diazotrophic and (b) photoautotrophic cells of T. erythraeum. Flux balance analysis was used to predict fluxes for both metabolic modes in a trichome of T. erythraeum. The thickness of the arrows depicts the amount of flux through the reaction normalized to the uptake of the carbon source. Dotted gray lines are available unused pathways. Diazotrophic cells have high flux through respiratory pathways, this protects nitrogenase from oxygen. As expected, photoautotrophic cells have high fluxes in the Calvin Benson Basham Cycle, which is the carbon fixing pathway. Abbreviations for metabolites are provided in abbreviations section. Full catalog of fluxes are provided in Additional file 5: Table S5
