Figure 1From: Path finding methods accounting for stoichiometry in metabolic networksMetabolite graph representation of the PEP: Pyr uptake system of glucose. (a) Metabolite graph; (b) metabolite graph restricted to atomic exchanges; (c) metabolite graph restricted to carbon exchanges. D-Glc, glucose; G6P, glucose 6-phosphate; PEP, phosphoenolpyruvate; Pyr, pyruvate.Back to article page
