Regulatory interactions within one of the evolved organisms. Labels representing transcription factors are organized in the following way: numbers indicate Kd (constant of ligand dissociation) of the TF; signs to the left of Kd symbolize the value of EffApo (effect of a free TF on transcription), with "-" meaning 0.1 – 0.33 (strong inhibition), "- " meaning 0.33 – 0.85 (weak inhibition), "= " meaning 0.85 – 1.15 (no effect), "+ " meaning 1.15 – 3.33 (weak activation, and "++" meaning 3.33 – 10 (strong activation). Signs to the right of Kd symbolize EffBound (the effect of the TF bound to the ligand). Fitness potential of this organism is 0.57.
