Figure 3From: Global transcriptomic analysis of an engineered Escherichia coli strain lacking the phosphoenolpyruvate: carbohydrate phosphotransferase system during shikimic acid production in rich culture medium Proposed metabolic and physiologic traits of E. coli PB12.SA22.based on relevant upregulated genes during EXP and STA GTA. OM, IM, Glycolysis, PPP, TCA and SA pathway are illustrated schematically. Arrows indicate the direction of transport or reaction; dotted arrows indicate suggested or unknown mechanisms.Back to article page
