Linking to Reactome

Linking to Reactome can be achieved by creating URLs containing the name of and an identifier from an “external” database in the following format:

http://www.reactome.org/cgi-bin/link?SOURCE=Database name&ID=identifier

Click here to see the external databases and list identifiers available in the current release of Reactome

Below are few concrete examples

  • UniProt accession numbers (the ‘AC’ line, preferred) and identifiers (the ‘ID’ line), e.g. UNIPROT:P30304

    http://www.reactome.org/cgi-bin/link?SOURCE=UNIPROT&ID=P30304

  • ChEBI identifiers, e.g. CHEBI:15422

    http://www.reactome.org/cgi-bin/link?SOURCE=CHEBI&ID=15422

  • COMPOUND identifiers, e.g. COMPOUND:C00002

    http://www.reactome.org/cgi-bin/link?SOURCE=COMPOUND&ID=C00002

  • Gene Ontology (GO) accession numbers, e.g. GO:0030060

    http://www.reactome.org/cgi-bin/link?SOURCE=GO&ID=0030060

  • Enzyme Classification (EC) numbers, e.g. EC:1.1.1.37

    http://www.reactome.org/cgi-bin/link?SOURCE=EC&ID=1.1.1.37

  • Entrez Gene, e.g. Entrez Gene:4171

    http://www.reactome.org/cgi-bin/link?SOURCE=Entrez+Gene&ID=4171

  • Reactome, e.g. Reactome:REACT_1

    http://www.reactome.org/cgi-bin/link?SOURCE=Reactome&ID=REACT_1

If you want to pass more than one identifier to Reactome, separate them with commas, e.g.:

  • http://www.reactome.org/cgi-bin/link?SOURCE=UNIPROT&ID=P30304,P00747,P00750
