Network Variation Maps

KEGG NETWORK represents a renewed attempt by KEGG to capture knowledge of diseases and drugs in terms of perturbed molecular networks (see Background of KEGG DISEASE). It accumulates variations of molecular interaction/reaction networks in terms of network variation maps (such as nt06210) consisting of network elements (such as N00014). The notation of network variation maps is as follows.
Network element Coloring
