W134 Nucleic Acids Research, 2009, Vol. 37, Web Server issue KEGG database, such as incomplete compounds and reactions (31,32). During the prospective works, we will integrate other resources, such as MetaCyc (16) to enhance the information of biochemical reactions in FMM database. AVAILABILITY The FMM web server will be continuously maintained and updated. The web server is now freely available at http://FMM.mbc.nctu.edu.tw/.
