Figure 5From: An efficient graph theory based method to identify every minimal reaction set in a metabolic network The metabolic network of Escherichia coli used in case study 1. The reactions in the minimal reaction set are shown by thick solid line. Reactions unique to minimal reaction set 1 (PPCK) is shown as dashed line and the unique reaction in minimal reaction set 2 (PYK) as dotted line. The unique reaction in minimal reaction set 3 (THD2) is a Transhydrogenase reaction involving only cofactors is given as a separate reaction.Back to article page
