Retrieve/ID mapping

Retrieving Rhea reactions

You can paste or upload a list of resource identifiers, separated by spaces or one per row, to retrieve the corresponding Rhea reactions.

Each job has a unique identifier and is stored for one week.

Supported resources

The following list of resources are supported:

Ontology versus exact mapping

For resources that are ontologies, like ChEBI and the Gene Ontology (GO), the default mapping uses the ontology's relationships to retrieve Rhea reactions that are linked either directly to your query IDs or indirectly via one of their related IDs (see this example).

You can choose the corresponding exact option to retrieve only Rhea reactions that are directly related to your query IDs.

Here is an example for the Gene Ontology that illustrates the difference between the options:

  • Gene Ontology:
    GO:0003884 is mapped to three Rhea reaction as it is the parent of two GO terms that are also mapped to Rhea reactions.
  • Gene Ontology (exact):
    GO:0003884 is mapped to one Rhea reaction.


Molecules/Compounds mapping

For resources of the category 'Molecules/Compounds', each query ID is first mapped to its major microspecies at pH 7.3 (shown in round brackets in the result column 'Your list...'), that is then mapped to Rhea reactions.
