This metabolic map consists of gut-specific pathway modules connected by their input and output compounds. The modules are clustered and colored according to their hierarchical classification (e.g. amino-acid degradation). Metabolites are represented by circles, while modules are represented by colored lines. The flow of compounds is from top to bottom unless the module is represented by a dashed line.
