eQuilibrator overview

equilibrator-api is a command-line API with minimal dependencies for calculation of standard thermodynamic potentials of biochemical reactions using the same data found on eQuilibrator website. It can be used without a network connection (after installation and initialization).

Current Features

  • Calculation of standard Gibbs potentials of reactions (together with confidence intervals).

  • Calculation of standard reduction potentials of half-cells.

  • Adjustment of Gibbs free energies to pH, ionic strength, and pMg (Magnesium ion concentration).

  • Pathway analysis tools such as Max-min Driving Force and Enzyme Cost Minimization (requires the equilibrator-pathway package).

  • Adding new compounds that are not among the 500,000 currently in the MetaNetX database (requires the equilibrator-assets package).
