I am using the KEGG REST API to retrieve plain text files of some genes of interest. For example:
http://rest.kegg.jp/get/enzyme:220.127.116.11 to obtain all info of the enzyme 18.104.22.168, including the genes associated with, or
http://rest.kegg.jp/find/genes/nifh to obtain a list of the "nifH" genes, associated with the tax code.
My question is: I can filter this result for a tax rank? for example, I only need the genes of bacteria, fungi and archaea
