Figure 3From: Designing optimal cell factories: integer programming couples elementary mode analysis with regulationIllustrative toy network. Illustrative toy network containing the metabolites A to C, and the reactions R1 to R6. All reactions are irreversible. The area inside the dashed box indicates the “cell interior”. The network consists of three EM: R1-R2-R3, R1-R6-R4-R3, and R5-R4-R3.Back to article page
