Figure 3From: MetRxn: a knowledgebase of metabolites and reactions spanning metabolic models and databasesVarious levels of structural information was available for models (main) and databases (inset). For every model, the majority of metabolites had full atomistic detail (blue). The smaller number of metabolites with partial atomistic detail (orange) such as genetic side chains, or with no atomistic detail (green) such as gene products, participated in few reactions.Back to article page
