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" consisting of "network elements". Each network element is identified by the N number (such as N00014) and each variation map is identified by the nt number (such as nt06210). The notation of network variation maps is as follows.
