With the continuous elaboration of high throughput experimental technologies, ever increasing amounts of data are accumulated for genomic and cDNA sequences, gene expression profiles, SNPs, protein-protein interactions, and protein 3D structures. However complete, such experimentally determined catalogs of genes, RNAs, and proteins only tell us about the building blocks of life. They do not tell us much about how life operates as a system, such as systemic functional behaviors of the cell or the organism.

KEGG, which is now funded mostly by this Research for the Future Program, is our attempt to actually perform synthesis from the building blocks to the functioning biological system. The synthesis is knowledge based. It is essential to computerize current knowledge about actual wiring (interactions) of building blocks in living cells. It is also necessary to understand basic principles of molecular interactions and chemical reactions that play key roles in dynamic interactions of the system with its environment.

The following three major KEGG databases are supported by this program:
