Application
Pyruvate Oxidase from Aerococcus sp. has been used in the amplex Red-based fluorescence assay for pyruvate. It is suitable for use in the preparation of biosensor for determination of thiamine (vitamin B1), and as a component in the constant part of the multi-enzyme biocatalytic cascade for the determination of biomarkers for traumatic brain injury (TBI) and soft tissue injury (STI).
Biochem/physiol Actions
Pyruvate Oxidase oxidises pyruvate to form acetate, hydrogen peroxide and carbon dioxide. Pyruvate oxidase requires flavin adenine dinucleotide (FAD), thiamine pyrophosphate (TPP) and magnesium as cofactors for its catalytic activity. Thiamine activates pyruvate oxidase activity.
Pyruvate Oxidase consists of four subunits with identical molecular weights. PoxB reacts with certain aldehydes and phosphate can be replaced by arsenate. Oxygen as well as several artificial compounds can function as electron acceptors[2]. Pyruvate Oxidase is activated by phospholipids as well as monomeric and micellar amphiphiles[3].
Physical form
Lyophilized powder containing buffer salt and sugar
Other Notes
One unit will produce 1.0 μmole of H2O2 per min during the conversion of pyruvate and phosphate to acetylphosphate and CO2 at pH 6.7 at 37 °C.
