Kegg:Reactions Scheme

Download WorkflowThe 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:
- determine all the reactions that the given metabolite participates in
- determine all the compounds that participate in these reactions
- filter certain compounds like H2O, ATP etc to avoid non-specific connections
- determine all the reactions that the compounds passing through step 3 participate in
- determine the enzymes that drive the reactions from step 4
- determine genes corresponding to the enzymes in step 5
- store the entrez gene ids as a text file

| 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 in 5. determine the enzymes that drive the reactions from step 4 6. determine genes corresponding to the enzymes in step 5 7. store the entrez gene ids as a text file |
