Fig. 4From: A numerical approach for detecting switch-like bistability in mass action chemical reaction networks with conservation lawsFutile signaling cycle. a SBGN [30] representation of the reaction network constructed using CellDesigner [31] and b its C-graph representation. E1 and E2 indicate alternative forms of a kinase enzyme. S is a substrate. S* is a substrate in a phosphorylated form (labeled with p on panel a). E1S and E2S are the enzyme:substrate complexesBack to article page
