Desulfobacter hydrogenophilus : pyruvate, water dikinase Inferred from experiment
Escherichia coli K-12 substr. MG1655 : phosphoenolpyruvate synthetase Inferred from experiment : ppsA

In Pathway: gluconeogenesis I , reductive TCA cycle I , glycolysis II (from fructose 6-phosphate) , glycolysis I (from glucose 6-phosphate)

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.

Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.

Mass balance status: Balanced.
