Conversion from a metabolic network to a graph representation. (a) Part of the Glycolysis Pathways, from BioCyc Database [5, 6]. (b) The resulting graph with the nodes (enzymes) and edges (enzyme-enzyme relations). (c) Table that represents known enzymes relations (EC numbers related are classified as +1 and non-related as -1).
