General description
Formerly E.C. number 1.1.3.2
Lactate oxidase is a globular flavoprotein and utilizes flavin mononucleotide (FMN) as the cofactor. The enzyme contains a major tyrosine in the substrate-binding pocket and a flavin adenine dinucleotide (FAD) active site. Lactate oxidase has several bacterial sources.
Application
Lactate Oxidase from Pediococcus sp. has been:
- used to functionalize the detection reservoirs for lactate analysis
- used in sequential enzymatic reactions to measure lactate production in the supernatants of microglial cultures
- immobilized onto a carbon electrode to generate a self-powered lactate sensor
Biochem/physiol Actions
Lactate oxidase is used in immobilization or enzyme-based labels for designing biochemical analytical devices such as immunosensors. This enzyme catalyzes the oxidation of lactate to produce pyruvate and H2O2. Lactate oxidase is useful in the first-generation biosensor approach for the electrochemical detection of lactate.
Other Notes
One unit will oxidize 1.0 μmole of L-lactate to pyruvate and H2O2 per min at pH 6.5 at 37 °C.

L-Lactate oxidase (LOX) belongs to a large family of flavoenzymes that catalyze oxidation of α-hydroxy acids. How in these enzymes the protein structure controls reactivity presents an important but elusive problem. LOX contains a prominent tyrosine in the substrate binding

Detection of analytes in complex biological samples, such as milk and blood, normally requires sample pretreatment. These pretreatment regimes reduce assay throughput and increase testing costs. Technologies that make it possible to eliminate sample pretreatment are of great industrial interest.

Nitrogen-doped carbon nanotubes (N-CNTs) provide a simple, robust, and unique platform for biosensing. Their catalytic activity toward the oxygen reduction reaction (ORR) and subsequent hydrogen peroxide (H(2)O(2)) disproportionation creates a sensitive electrochemical response to enzymatically generated H(2)O(2) on the N-CNT
