Pyruvate oxidase


In enzymology, pyruvate oxidase is an enzyme that catalyzes the chemical reaction
The three substrates of this enzyme are pyruvic acid, phosphate, and oxygen. Its products are acetyl phosphate, carbon dioxide, and hydrogen peroxide.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with oxygen as acceptor. The systematic name of this enzyme class is pyruvate:oxygen 2-oxidoreductase . Other names in common use include pyruvic oxidase, and phosphate-dependent pyruvate oxidase. This enzyme participates in pyruvate metabolism. It has 2 cofactors: flavin [adenine dinucleotide|FAD], and Thiamin diphosphate.
