This is KEGG general site.
But I think it's better to start from this site below:
Using the KEGG browser, you can:
view enzymes related to a pathway.
view predicted genes related to a pathway.
view maps of reference pathways.
browse through KEGG pathways.
compare models to KEGG assignments in related organisms.
The tutorial has "clickable" words or even sentences, and the click will lead you to what you have chosen.
There is a paper describing pathways in KEGG:
It answers your question to some extent, doesn't it?
I hope it may help.
There is another way to get all pathways for any organism.
Select organism – press on ‘organism’ , enter your organism 4-letter name near
‘Find three- or four-letter KEGG organism code’ , press ‘select’ and ‘GO’.
After that you will have all pathways KEGG has for the organism.
‘map’ to the left of the ‘organism’ will be replace with its name.
with all pathways KEGG found for it.
You can even generate possible reaction paths:
I selected ' Pathways 2' from the links on the left panel:
ehi00600 Sphingolipid metabolism - Entamoeba histolytica
ehi01100 Metabolic pathways - Entamoeba histolytica
Start again - back to your question:
Retrieve all reactions for a given kegg pathway
1) Start here
Choose in the table
KEGG metabolic pathways
KEGG regulatory pathways
KEGG Metabolic Pathways -
go to the line 'browse through KEGG pathways'.
2) Do go to the Table: JGI Genome portal tutorial,
Other functions below and
click on the pathways you needed – regulatory or metabolic ones
I have not seen the way you need: Find a pathway then Retrieve all the reactions
I think you can go only in the opposite direction:
Retrieve the full list of all the reactions as I described above, then find a pathway or pathways you need among them
