Species-Metabolite Relationship Database&l … Species-Metabolite Relationship Database<br />
For systematic and comprehensive understanding of species-specific metabolic diversities, we have designed a database system, KNApSAcK, for searching relationships between metabolites and species (Shinbo et al., 2006). The database has incorporated a tool for analyzing datasets acquired by FT-ICR/MS. KNApSAcK consists of information about metabolite names, molecular formulas, structural formulas, species names, Chemical Abstract Service (CAS) registration numbers, and biological activities. All the KNApSAcK data were collected from published literature. Metabolites are checked for the accuracy of both molecular formulas and structural formulas using the CAS database, and the CAS registration numbers are obtained from the same database. Species names were checked for the accuracy of spelling using the National Center for Biotechnology Information Taxonomy Browser (http://www.ncbi.nlm.nih.gov/Taxonomy/), the Plants Database (http://plants.usda.gov/index.html), and the Integrated Taxonomic Information System (http://www.itis.usda.gov/). A total of 25,930 metabolite-species pairs encompassing 11,075 metabolites and 8,557 species were obtained from about 7,600 published references (January 19, 2006). These data have been stored on a server, which is located in the Nara Institute of Science and Technology. The database system is freely available at http://kanaya.naist.jp/KNApSAcK/ on the Java 1.4.2. naya.naist.jp/KNApSAcK/ on the Java 1.4.2.
