     KEGG (Kyoto Encyclopedia of Genes and Genomes) maintains pathway
     data for various organisms. YEASTPATH maps probe identifiers to
     the identifiers used by KEGG for pathways in which the genes
     represented by the probe identifiers are involved

_D_e_t_a_i_l_s:

     Each KEGG pathway has a name and id. Pathway name for a given
     pathway id can be obtained using the KEGG data package that can
     either be built using AnnBuilder or downloaded from Bioconductor
     <URL: http://www.bioconductor.org>.

     Graphic presentations of pathways are searchable at
     url{http://www.genome.ad.jp/kegg/pathway.html} by using pathway
     ids as keys.   

     Mappings were based on data provided by:
