Figure 14

A 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.
