KEGG DB Links

KEGG objects are highly integrated by mutual links within KEGG, and are also linked to related entries in outside databases. The following table shows the links maintained by KEGG. There are additional links maintained by GenomeNet (see LinkDB), including those created by outside databases.

1 Outside links for ID conversion allow, for example, outside identifiers to be used in KEGG Mapper analysis. The Conv ID tool in KEGG Mapper may be used to convert GeneIDs, ProteinIDs or UniProt IDs to KEGG identifiers.
2 Parentheses for hsa (Homo sapiens) only.
