| Official Name |
|---|
| Pyruvate oxidase.
|
| Alternative Name(s) |
|---|
| Phosphate-dependent pyruvate oxidase. |
| Pyruvic oxidase. |
| Reaction catalysed |
|---|
| Pyruvate + phosphate + O(2) <=> acetyl phosphate + CO(2) + H(2)O(2) |
| Cofactor(s) |
|---|
| FAD; Thiamine(1+) diphosphate(1-).
|
| Comment(s) |
|---|
- Two reducing equivalents are transferred from the resonant
carbanion/enamine forms of 2-hydroxyethyl-thiamine-diphosphate to the
adjacent flavin cofactor, yielding 2-acetyl-thiamine diphosphate
(AcThDP) and reduced flavin.
- FADH is reoxidized by O(2) to yield H(2)O(2) and FAD and AcThDP is
cleaved phosphorolytically to acetyl phosphate and thiamine
diphosphate.
