Nucleoside oxidase
Nucleoside oxidase (EC 1.1.3.28) is an enzyme with systematic name nucleoside:oxygen 5'-oxidoreductase.[1][2] This enzyme catalyses the following chemical reaction
- inosine + O2 9-riburonosylhypoxanthine + H2O
- (1a) 2 inosine + O2 2 5'-dehydroinosine + 2 H2O
- (1b) 2 5'-dehydroinosine + O2 2 9-riburonosylhypoxanthine
