modificationOfTwoSubstratesI -- an example chemical reaction motif

In this system, two cycles are connected through a joint catalyzing kinase and a joint catalyzing phosphotase [Feliu, Wiuf].

o1 : ReactionNetwork

In the motif Modification of Two Different Substrates I, the symbols used in the chemical reactions have the following meaning:

S_i and P_i are substrates with i = 0, 1, 2 phosphorylated sites, E is a kinase and F is a phosphotase, X and Y are the intermediate complexes formed by the enzymes E and F, respectively.

To rename species, use substitute(ReactionNetwork,List).
