Crosstalk between metabolic pathways. The network diagram represents the number of enzymes shared between pathways. Each pathway is represented by a node. Connections (edges) between these nodes represent the number of enzymes common to each pathway. Nodes are colored according to their superclass category; node size indicates the number of enzymes in that pathway; and thickness of edges indicate the number of enzymes common to each pathway (see inset keys).
