Flux variability analysis showing PEP utilization capacity represented by the flux through PEP hydratase as a function of cellular biomass yield for different carbon sources predicted by the iEco-F420 metabolic model of E. coli. Minimum and maximum fluxes are shown as blue and red, respectively. PEP: phosphor-enol pyruvate; 2PG: 2-phospho glycerate. Horizontal dashed lines do not correspond to any actual flux values; instead, they serve as hypothetical lines above which glycolysis drives carbon flow (2PG is metabolised to PEP).
