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: aldehyde ferredoxin oxidoreductase
Enzyme Commission Synonyms: AOR
Taxonomic Range: Archaea
Standard Gibbs Free Energy (ΔrG'° in kcal/mol): -13.707764 [Latendresse13]
Enzyme Commission Summary:
This is an oxygen-sensitive enzyme that contains tungsten-molybdopterin and iron-sulfur clusters. Catalyses the oxidation of aldehydes (including crotonaldehyde, acetaldehyde, formaldehyde and glyceraldehyde) to their corresponding acids. However, it does not oxidize glyceraldehyde 3-phosphate [see EC 22.214.171.124, glyceraldehyde-3-phosphate dehydrogenase (ferredoxin)]. Can use ferredoxin or methyl viologen but not NAD(P)+ as electron acceptor.
