Some notable examples:
For a commented initial example, see: e. Coli K-12 MG1655 gene thrA.
But BioCyc is generally better otherwise.
I don't think it has any advantage over KEGG however, besides historical interest? Maybe slightly more manual layout and so more beautiful?
Design software for synthetic biological circuit.
The input is in Verilog! Overkill?

A metabolic pathway is a connected sequence of enzyme-catalyzed chemical reactions in metabolism, with a reaction product of one step serving as a substrate for another. A pathway boundary is a choice about which transformations to count: glycolysis ends at pyruvate, whereas subsequent fermentation or cellular respiration changes the final material balance. Adding the individual chemical equations cancels internal intermediates and exposes the net stoichiometry; it does not determine the reaction rate.
