The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the direction in which it was curated.
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: nucleoside oxidase
Standard Gibbs Free Energy (ΔrG'° in kcal/mol): -113.9811 [Latendresse13]
Enzyme Commission Summary:
Other purine and pyrimidine nucleosides (as well as 2'-deoxynucleosides) are substrates, but ribose and nucleotides are not substrates.
The overall reaction takes place in two separate steps, with the 5'-dehydro nucleoside being released from the enzyme to serve as substrate for the second reaction.
The two reactions are:
This enzyme differs from EC 184.108.40.206, nucleoside oxidase (H2O2-forming), as it produces water rather than hydrogen peroxide.
