Complexity reduction by symmetry: Uncovering the minimal regulatory network for logical computation in bacteria
Fig 5
Circuits in the GRN of E. coli.
(A) The minimal GRN of E. coli and the circuits embedded in it, shown with red links for the symmetry breaking inputs to the toggle-switch fliz-csgd. The biggest SCC is in charge mostly of pH responses. Colored nodes represent fibers. ( B) The two-node SCCs and ( C) the soxS SCC and its circuits. For each circuit, the incoming signals that break the symmetry are shown.
