kegger

Interact with the KEGG API using Python and Pandas

Retrieve genes and KEGG pathway for your favorite organisms in the KEGG database

I developed this primarily for use in RNAseq analysis and organizing gene expression patterns by KEGG pathways

Here are some quick examples:

Get all pathways from E. coli

>>> import kegger as kg
>>> org = "eco"

>>> org_pathways = kg.list_all_pathways(org)
>>> org_pathways.head()
     pathid                                        description
0  eco01100  Metabolic pathways - Escherichia coli K-12 MG1655
1  eco01110  Biosynthesis of secondary metabolites - Escher...
2  eco01120  Microbial metabolism in diverse environments -...
3  eco01200   Carbon metabolism - Escherichia coli K-12 MG1655
4  eco01210  2-Oxocarboxylic acid metabolism - Escherichia ...

Get a specific pathway:

>>> import kegger as kg
>>> pathid = "eco00190" # Oxidative phosphorylation - Escherichia coli K-12 MG1655
>>> org = "eco"
>>> path_record = kg.get_path(pathid)
>>> path_dict = kg.kegg_parser(path_record)

>>> print(path_dict.keys())
dict_keys(['ENTRY', 'NAME', 'CLASS', 'PATHWAY_MAP', 'MODULE', 'ORGANISM', 'GENE', 'ORTHOLOG', 'COMPOUND', 
           'REFERENCE', 'AUTHORS', 'TITLE', 'JOURNAL', 'KO_PATHWAY'])

>>> path_dict.get("GENE")
