An annotation data file that maps LocusLink or Open Reading Frame ids KEGG pathway ids


KEGGEXTID2PATHID maps LocusLink (for human, mouse, and rat) and Open Reading Frame (for yeast) ids to KEGG pathway ids.


This is an environment object containing key and value pairs. Keys are LocusLink ids for human, mouse, and rat and Open Reading Frame (ORF) ids for yeast and values are the corresponding KEGG pathway ids. Values are vectors of length 1 or greater depending on whether a given external id can be mapped to only one or more KEGG pathway ids. NAs are assigned to LocusLink or ORF ids that can not be mapped to any pathway id.

KEGG pathway ids are the identifiers used by KEGG for various pathways.

Mappings between KEGG pathway ids and pathway names can be obtained through another environment named PATHID2NAME.

Mappings were based on data provided by:
