KEGG Pathway是京都基因与基因组百科全书(KEGG)的核心子数据库之一,主要用于系统解析生物体内的代谢通路、分子相互作用网络及其生物学功能。它通过整合基因、酶、化合物、疾病与药物等数据,为研究人员提供通路可视化、功能注释及跨物种比较等分析工具,在基因组学、代谢工程和疾病机制研究...

显然GO里的pathway都是人手动注释的,是基于证据的(证据的种类),BP的大多数证据是IBA(同源)和IMP(突变型),如果是mutant那就是causal的。gene是固定在基因组上的,就那么些,而terms则是人为定义的,类似于GWAS的表型,是人根据自己的理解认知而定义出的一个宏观和具体或抽象的概念,理论上可以有无数个terms。本质是...

KEGG指的是京都基因与基因组百科全书,通常我们使用KEGG中的pathway模块,将基因映射到某些通路上,了解基因参与生物体中的代谢过程等。 对于模式生物,GO和KEGG富集分析实现起来比较容易,对于非模式生物来说还是需要花点时间和精力。对于模式生物的GO和KEGG富集分析,网上教程案例挺多的。对于非模式生物,以小麦为例,进行下面...

Firstly, two HMM profile-based KOs (K00192 and K00195) of the Wood–Ljungdahl pathway (M00377) were chosen to search the genomes using the KEGG tools, as stated above. The results with the most hits were further chosen and filtered. Then, through the KEGG_Extractor, the merged results ...
