Fig. 4

The characteristic graph of the small HSM network from Fig. 1 for the binding affinity ordering b2.dis < b3.dis < b3.as < b2.as for s2. Each mode in the graph can be identified by a unique binding site state combination; it is labeled by the concentration change direction for each protein. SSCs that contain attractors are either blue, with bold margins, or pink, with narrow margins. Pink attractors correspond to a single cycle whereas blue attractors comprise at least two cycles and at least one branching point leading into different cycles
