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.

Enzyme Commission Primary Name: phosphonopyruvate decarboxylase

Enzyme Commission Synonyms: 3-phosphonopyruvate carboxy-lyase

Standard Gibbs Free Energy (ΔrG in kcal/mol): -2.8417358 Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
Catalyzes a step in the biosynthetic pathway of 2 aminoethylphosphonate, a component of the capsular polysaccharide complex of Bacteroides fragilis. Activated by the divalent cations Mg(2+), Ca(2+) and Mn(2+). Pyruvate and sulfopyruvate can also act as substrates, but more slowly.
