Figure 11From: (Im)Perfect robustness and adaptation of metabolic networks subject to metabolic and gene-expression regulation: marrying control engineering with metabolic control analysisControl system structure of a pseudo-integral or an ideal integral control problem. hTrsc(·) denotes the transcription process. gTrnl(·) denotes the rate of protein synthesis. The pseudo-integral control system becomes an ideal integral control only when the dashed line connecting the degradation rate kED is removed.Back to article page
