Nucleoside oxidase

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


 * inosine + O2 $$\rightleftharpoons$$ 9-riburonosylhypoxanthine + H2O
 * (1a) 2 inosine + O2 $$\rightleftharpoons$$ 2 5'-dehydroinosine + 2 H2O
 * (1b) 2 5'-dehydroinosine + O2 $$\rightleftharpoons$$ 2 9-riburonosylhypoxanthine

This enzyme could use other purine and pyrimidine nucleosides (as well as 2'-deoxynucleosides) as substrates.
