Learn how to explore ΔG information in GEMs and predict custom reaction thermodynamics
dGbyG offers two main services for thermodynamic analysis:
Enter a query for model, reaction, metabolite, or gene using BiGG IDs or names. Optionally filter by a specific model.
Results are grouped into four sections:
Click “Reaction Gibbs Energy” to expand detailed ΔG data.
Includes BiGG ID, name, ΔrG° values, SD and reaction equations across different models.
Shows metabolite identifiers, chemical formula, structure (if available), and related reactions.
Provides gene ID, models containing the gene, linked reactions and GPR information.
ΔrG = ΔrG° + RT ln Q
Troubleshooting: No results? Check spelling or filters. “NaN” means missing info in model/metabolites.
Supported: SMILES, InChI, InChI_Key, KEGG, MetaNetX, HMDB, Name, BiGG (universal), ChEBI, PubChem, Mixed.
✔ Recommended for accuracy: SMILES or InChI
BiGG ID users: remove compartment suffix (e.g., succ_c → succ)
A + B = C2 H2OTYPE:IDSample equations available via auto-fill examples.
The results show:
Enter multiple equations (one per line). All reactions share the same identifier type and global pH / I / pMg / E settings. Temperature is fixed at 298.15 K.
