Figure 5From: Comparison on extreme pathways reveals nature of different biological processesMatrix formalism of the TRN model. (A) The regulatory state matrix R * of the toy model in which the regulatory rules are: A + B → Protein 1 ; C → Protein 2 ; D → Protein 2 . The environmental state of R * is that metabolites A and D are present while B and C are absent. (B) The corresponding R new * of R * .Back to article page
