The Becker Medical Library currently hosts and manages a local mirror of the KEGG database for academic use by the Washington University community. Funding for the site license is made possible through a joint partnership of the Center for Genome Sciences & Systems Biology and the McDonnell Genome Institute.

The master Kyoto KEGG FTP site can be accessed directly while on campus, but the connection is extremely slow and can be unreliable.

You can learn more about KEGG at the main site.


The KEGG versions made available on this site will be updated every other month with the two most recent versions being maintained.

If you need a version of KEGG that is more recent than what is available here, please contact Maze Ndonwi, Senior Support Scientist at Becker Medical Library.

* Do not rely on this site for outdated versions of KEGG. Please store your own copy for long term availability.
