ENZYME entry: EC

Accepted 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)
FAD; Thiamine diphosphate.
  • 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.
