A thiamine oxidation enzyme (thiamine oxidase) is an oxidation-reduction enzyme catalyzing the next chemical reaction.
According to the equation, this reaction is caused with two phases. At first thiamine is oxidized and becomes thiamine aldehyde and it is oxidized more and becomes the thiamine acetic acid. In this reaction, I use FAD as cofactor.
The organization name is thiamine:oxygen 5-oxidoreductase, and another name has thiamin dehydrogenase, thiamine dehydrogenase, thiamin:oxygen 5-oxidoreductase.
