Figure 14From: (Im)Perfect robustness and adaptation of metabolic networks subject to metabolic and gene-expression regulation: marrying control engineering with metabolic control analysisA schematic diagram of the simplified leucine biosynthetic pathway model. Eu represents Leu4 and Leu9, E1 represents Leu1, E2 represents Leu2, I1 and I2 denote αIPM (α-isopropylmalate) and βIPM respectively. The source is pyruvate and P represents leucine. The supply and demand modules of the pathway are shown in shading.Back to article page
