ID   1.1.3.28
DE   nucleoside oxidase.
CA   inosine + O2 = 9-riburonosylhypoxanthine + H(+) + H2O.
CC   -!- Other purine and pyrimidine nucleosides (as well as
CC       2'-deoxyribonucleosides) are substrates, but ribose and nucleotides
CC       are not substrates.
CC   -!- The overall reaction takes place in two separate steps, with the
CC       5'-dehydro nucleoside being released from the enzyme to serve as
CC       substrate for the second reaction.
CC   -!- Differs from EC 1.1.3.39 as it produces water rather than hydrogen
CC       peroxide.
