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 22.214.171.124, nucleoside oxidase (H2O2-forming), as it produces water rather than hydrogen peroxide.
