General description
Lactate oxidase (LOX) is a flavin mononucleotide (FMN)-dependent enzyme and is a member of the α-hydroxy-acid oxidase flavoenzyme family.
Application
Lactate Oxidase from Aerococcus viridans has been used as a:
- supplement in the culture medium to convert extracellular lactate to pyruvate
- coating on glass beads for electrochemical detection of lactate from a single cell by a push-pull nozzle system
- coating on multi-branched gold nanoparticles (GNPs) for the simultaneous colorimetric detection of lactate in saliva by paper-based multiplexed device
Biochem/physiol Actions
Lactate oxidase (LOX) catalyzes the oxidation of lactate to pyruvate and hydrogen peroxide in the presence of an FMN co-factor. The enzyme aids in the determination of L-lactate indirectly by measuring the hydrogen peroxide formed in the reaction.
Other Notes
One unit is defined as the amount of enzyme which generates 1m mole of Hydrogen Peroxide per minute at 37°C under standard assay conditions.
