Figure 2.

This is a pathway collage showing the pathways in the constant pathway cost solution for the McDonnell data set and highlighting most of the covered compounds. Three covered compounds (NAD+, coenzyme A, guanine) are not shown in the collage because they are considered side compounds of reactions (meaning they are not shared between consecutive reactions in the pathway) and are not drawn by the pathway layout algorithm. Two compounds, glycerone phosphate and 5-phospho-alpha-d-ribose 1-diphosphate are shown on the collage under different names, DHAP and PRPP.
