Kegg annotation for gene

Hi, is there a package in R or python that I can use to find the pathways associated to a gene if I input a list of genes? I have tried using KEGG search mapper but I have a list of a thousand genes or so and need the pathways for each gene so this is not my most ideal method. I am not trying to do any analysis, I just want to know the pathways a gene is in. An example output I am thinking is each individual gene with a list of the pathways associated with it. Thank you!

Take a look at GeneSCF (LINK). There should be past posts by the author of GeneSCF to find this information from KEGG.

I've used the KEGG API (https://www.kegg.jp/kegg/rest/keggapi.html) to download lists of KO numbers for each module, pathway, and enzyme. So for pathways it would be: http://rest.kegg.jp/link/ko/path

These lists don’t have the pathway names, but you can also access them like this: http://rest.kegg.jp/list/path

You would just have to join them after that!

Alternatively there is the package KeggRest. But it might be more than what you need at the moment

As an alternative to KEGG, the rWikiPathways package in Bioconductor makes this easy: https://bioconductor.org/packages/release/bioc/html/rWikiPathways.html. Once you've installed the package, then you can search by gene symbols (e.g., HGCN symbols) such "TNF" and get a dataframe listing pathways by row:

findPathwaysByXref('TNF','H')

You can alternatively search by NCBI Entrez Gene IDs or Ensembl IDs, etc. See examples and link to datasource codes in the man page:

?findPathwayIdsByXref
