The KEGG resource for deciphering the genome .

KEGG(京都基因与基因组百科全书)是基因组破译方面的数据库。在后基因时代一个重大挑战是如何使细胞和有机体在计算机上完整的表达和演绎，让计算机利用基因信息对更高层次和更复杂细胞活动和生物体行为作出计算推测。为达到此目的，人们建立了一个在相关知识基础上的网络推测计算工具。在给出染色体中一套完整的基因的情况下，它可以对蛋白质交互（互动）网络在各种细胞活动起的作用作出预测。 KEGG 的PATHWAY 数据库整合当前在分子互动网络（比如通道，联合体）的知识，KEGG 的GENES/SSDB/KO 数据库提供关于在基因组计划中发现的基因和蛋白质的相关知识，KEGG 的COMPOUND/GLYCAN/REACTION数据库提供生化复合物及反应方面的知识。

English Summary：

A grand challenge in the post-genomic era is a complete computer representation of the cell and the organism, which will enable computational prediction of higher-level complexity of cellular processes and organism behavior from genomic information. Toward this end we have been developing a knowledge-based approach for network prediction, which is to predict, given a complete set of genes in the genome, the protein interaction networks that are responsible for various cellular processes. KEGG at http://www.genome.ad.jp/kegg/ is the reference knowledge base that integrates current knowledge on molecular interaction networks such as pathways and complexes (PATHWAY database), information about genes and proteins generated by genome projects (GENES/SSDB/KO databases) and information about biochemical compounds and reactions (COMPOUND/GLYCAN/REACTION databases). These three types of database actually represent three graph objects, called the protein network, the gene universe and the chemical universe. New efforts are being made to abstract knowledge, both computationally and manually, about ortholog clusters in the KO (KEGG Orthology) database, and to collect and analyze carbohydrate structures in the GLYCAN database.
