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:188.8.131.52 to obtain all info of the enzyme 184.108.40.206, 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
