LIGAND is a composite database consisting of three sections and containing the information of chemical substances, chemical reactions and enzymes that catalyze reactions. The COMPOUND section is a collection of metabolic compounds, as well as macromolecules, chemical elements and other chemical substances in a living cell. The ENZYME section is a collection of all known enzymatic reactions, together with the information of enzyme molecules, classified according to the EC (Enzyme Commission) numbers. The REACTION section is a new addition to the database containing metabolic reactions that appear in the pathway diagrams of the KEGG/PATHWAY database and/or in the ENZYME section. The LIGAND database can be accessed through the WWW (http://www.genome.ad.jp/dbget/ligand.html) or may be downloaded by anonymous FTP (ftp://kegg.genome.ad. jp/molecules/ligand).
LIGAND是一个复合数据库,由三个部分组成,包含化学物质、化学反应以及催化反应的酶的信息。化合物部分是代谢化合物的集合,以及活细胞中的大分子、化学元素和其他化学物质。酶部分是所有已知酶促反应的集合,以及根据酶委员会(EC)编号分类的酶分子信息。反应部分是数据库的新增内容,包含出现在KEGG/途径数据库的途径图和/或酶部分中的代谢反应。LIGAND数据库可以通过万维网(http://www.genome.ad.jp/dbget/ligand.html)访问,也可以通过匿名FTP(ftp://kegg.genome.ad.jp/molecules/ligand)下载。
