Figure 1From: The regulatory network of E. coli metabolism as a Boolean dynamical system exhibits both homeostasis and flexibility of responseMap of the transcriptional regulatory network controlling metabolism in E. coli. In this figure, there are genes coding for the TFs (pink circles), genes coding for enzymes (brown circles), external metabolites (green squares), certain internal fluxes (purple parallelograms), stimuli (yellow triangles) and other conditions (blue diamonds).
