Figure 5. Networks of direct and indirect regulatory interactions in the case of (A) glycolysis and (B) gluconeogenesis.

Figure 5

The networks are computed from the models Inline graphic and Inline graphic, taking into account allosteric effects (see Sec. 3 of Text S3). The boxes represent fast coupling species, mediating the influence of metabolism and signal transduction on gene expression: CrpInline graphiccAMP, free FruR, RpoSInline graphicRssB*, and DNA supercoiling. The influence of the enzymes and other slow species on the concentration of the fast coupling species are represented by +/− signs.
