LINK
Name
link – find related entries by using database cross-references
URL form
http://rest.kegg.jp/link/<target_db>/<source_db>

<target_db> = <database>
<source_db> = <database>

<database> = pathway | brite | module | ko | genome | <org> | vg | ag | compound |
             glycan | reaction | rclass | enzyme | network | variant | disease |
             drug | dgroup | environ | atc | jtc | ndc | yj | pubmed

http://rest.kegg.jp/link/<target_db>/<dbentries>

<dbentries> = KEGG database entries of the following <database>
<database> = pathway | brite | module | ko | genome | <org> | vg | ag | compound |
             glycan | reaction | rclass | enzyme | network | variant | disease |
             drug | dgroup | environ | genes | atc | jtc | ndc | yj | pubmed
Description
This operation allows retrieval of cross-references within all KEGG databases, as well as pubmed. It is useful for finding various relationships, such as relationships between genes and pathways. The first form allows retrieval of database to database cross-references, while the second form allows retrieval for a selected number of entries. The database name "genes" may be used only for "ko" entries in the second form.
Examples
/link/pathway/hsa       KEGG pathways linked from each of the human genes
/link/hsa/pathway       human genes linked from each of the KEGG pathways
/link/pathway/hsa:10458+ece:Z5100       KEGG pathways linked from a human gene and an E. coli O157 gene
/link/genes/K00500      List of genes with the KO assignment of K00500
/link/hsa/hsa00010      List of human genes in pathway hsa00010
/link/ko/map00010 or /link/ko/ko00010       List of KO entries in pathway map00010 or ko00010
/link/rn/map00010 or /link/rn/rn00010       List of reaction entries in pathway map00010 or rn00010
/link/ec/map00010 or /link/ec/ec00010       List of EC number entries in pathway map00010 or ec00010
/link/cpd/map00010      List of compound entries in pathway map00010
/link/drug/ndc      NDC codes linked from KEGG DRUG entries
/link/ndc/D00564        NDC codes that correspond to given a KEGG DRUG entry
