Fig. 1From: Examining Escherichia coli glycolytic pathways, catabolite repression, and metabolite channeling using Δpfk mutantsRedistribution of fluxes between the three primary glucose catabolic pathways: EMPP (red), EDP (blue), and OPPP (orange) via the knockout of pfkA and overexpression of EDP genes (edd and eda). Table on the right presents the estimated flux ratio between the three pathways for each strain. The dashed arrows represent a possible interference (unannotated) source from glycogen metabolism [27]Back to article page
