Example of regulatory edge. In Figure 3, reaction T 1 produces compound P 1, which participates in reaction T 2. Protein P 0 participates in reaction T 2 which in turn produces P 2. In the figure the bidirectional edge (blue edge) between P 1 and T 2 is a regulatory edge that makes sure that T 2 will not fire until P 1 is produced by T 1 irrespective of the amount of P 0 present.
