The purpose of this workflow is to determine all the enzymes/genes that participate in a radius of 2 reaction steps around a given metabolite. Broadly, the scheme involves the following steps: 1. determine all the reactions that the given metabolite participates in 2. determine all the compounds that participate in these reactions 3. filter certain compounds like H2O, ATP etc to avoid non-specific connections 4. determine all the reactions that the compounds passing through step 3 participate...
