I was using KEGG API to download certain information related to enzymes and pathways. KEGG API expects certain inputs for some of the methods in the API. For example, here is a call
get_enzymes_by_compound(string:compound_id). This method expects a
compound_id. A sample compound id given in the KEGG API reference manual is
cpd:C00345. But there is no specific function to get all the mappings of the compounds and corresponding internal ids. Similar is the case of glicanid, reactionid etc., Has any one used KEGG API to download this information and if so, how are the input parameters like Compundid, enzymeid, reaction_id etc., are taken from? Please help me in this regard. Thank you in advance.
