How does BioModels Database differ from Reactome?
Reactome is a database of reactions and pathways, not a database of quantititative models. The SBML files exported by Reactome (or KEGG for that matter) do not contain any quantitative information, whether quantities (amount or concentration of species) or kinetics. Reactome aims to describe the human cellular pathways accurately and in great details, not to distribute abstract quantitative description of their functions.
