I would have a look at Rhea. Which is not a pathway database but a which chemical reactions are out there in biology. This can be combined with the data in UniProt to build metabolic pathways. And then at metanetx.org to build draft metabolic models. We recently had a collaboration with AWS Open Data+Neptune to show how easy it is to combine Rhea,ChEBI and UniProt in your own database.
