Kyoto Encyclopedia of Genes and Genomes (KEGG)

KEGG is a suite of databases and associated software, integrating our current knowledge on molecular interaction networks in biological processes (PATHWAY database), the information about the universe of genes and proteins (GENES/SSDB/KO databases), and the information about the universe of chemical compounds and reactions

COMPOUND/GLYCAN/REACTION databases)

The project website can be found at http://www.genome.ad.jp/kegg/kegg2.html
