Molecule's external Identifier


What is the resource of your supplied ID? see: Reactome External Identifiers


Either "pathways" or "reactions".


Numeric or Character: NCBI Taxonomy identifier (Human is 9606), species name (e.g. "Homo sapiens") or Reactome DbId (e.g Homo sapiens is 48887). See rba_reactome_species or Reactome Data Schema: Entries: Species.


rbioapi option(s). See rba_options's arguments manual for more information on available options.
