Nucleoside oxidase (H2O2-forming)

Nucleoside oxidase (H2O2-forming) is an enzyme with systematic name nucleoside:oxygen 5'-oxidoreductase (H2O2-forming). This enzyme catalyses the following chemical reaction


 * adenosine + 2 O2 + H2O $$\rightleftharpoons$$ 9-riburonosyladenine + 2 H2O2 (overall reaction)
 * (1a) adenosine + O2 $$\rightleftharpoons$$ 5'-dehydroadenosine + H2O2
 * (1b) 5'-dehydroadenosine + O2 + H2O $$\rightleftharpoons$$ 9-riburonosyladenine + H2O2

This enzyme contains Heme and belongs to a flavoprotein family.
