Aquifex aeolicus VF5 Reaction: 6.4.1.7

Superclasses: Reactions Classified By Conversion Type Simple Reactions Chemical Reactions
Reactions Classified By Substrate Small-Molecule Reactions

EC Number: 6.4.1.7

In Pathway: reductive TCA cycle II

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.

Enzyme Commission Primary Name: 2-oxoglutarate carboxylase

Enzyme Commission Synonyms: oxalosuccinate synθse, carboxylating factor for ICDH (incorrect), CFI, OGC

Standard Gibbs Free Energy (ΔrG in kcal/mol): -9.341309 Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
A biotin-containing enzyme that requires Mg2+ for activity. It was originally thought [Aoshima04] that this enzyme was a promoting factor for the carboxylation of 2-oxoglutarate by EC 1.1.1.41, isocitrate dehydrogenase (NAD+), but this has since been disproved [Aoshima06]. The product of the reaction is unstable and is quickly converted into isocitrate by the action of EC 1.1.1.41 [Aoshima06].
