Accepted name: thiamine oxidase
Reaction: thiamine + 2 O2 + H2O = thiamine acetic acid + 2 H2O2
Other name(s): thiamin dehydrogenase; thiamine dehydrogenase; thiamin:oxygen 5-oxidoreductase
Systematic name: thiamine:oxygen 5-oxidoreductase
Comments: A flavoprotein (FAD). The product differs from thiamine in replacement of -CH2.CH2.OH by -CH2.COOH; the two-step oxidation proceeds without the release of the intermediate aldehyde from the enzyme.

Accepted name: nucleoside oxidase
Reaction: inosine + O2 = 9-riburonosylhypoxanthine + H2O
(1a) 2 inosine + O2 = 2 5′-dehydroinosine + 2 H2O
(1b) 2 5′-dehydroinosine + O2 = 2 9-riburonosylhypoxanthine
Systematic name: nucleoside:oxygen 5′-oxidoreductase
Comments: Other purine and pyrimidine nucleosides (as well as 2′-deoxyribonucleosides) 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. This enzyme differs from EC, nucleoside oxidase (H2O2-forming), as it produces water rather than hydrogen peroxide.
