KEGG: Kyoto Encyclopedia of Genes and GenomesDatabase Content

Pathway maps, molecular catalogs, genome maps and gene catalogs that capture knowledge about interactions in terms of information pathways. KEGG comprises several databases, including BRITE (protein-protein interactions), PATHWAY (interaction networks for cellular processes), and LIGAND (chemical compounds and chemical reactions). KEGG Atlas is a new tool for the global analysis of metabolic pathways.
