一般描述
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.
应用
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
生化/生理作用
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.
其他说明
One unit will oxidize 1.0 μmole of L-lactate to pyruvate and H2O2 per min at pH 6.5 at 37 °C.

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

In this work, a novel simple and sensitive electrochemical immunosensor was developed based on lactate oxidase as a single electrochemical probe for the detection of carcinoma antigen 125 (CA125). Chitosan-gold nanoparticle/multiwall carbon nanotube/graphene oxide (CS-AuNP/MWCNT/GO) was used as the electrode

By making use of the aggregation-induced emission feature of silole 1 and the cascade reactions among l-lactic acid (LA), lactate oxidase (LOD), and dodecanoic hydrazine (DH), a new fluorometric "turn-on" method is developed for the detection of LA.

An amperometric sensor for lactate quantification is presented. The developed biosensor requires only 0.2 U of lactate oxidase, which is immobilized in a mucin/albumin hydrogel matrix. By protecting the platinum surface with a Nafion membrane, typical interference related to negatively

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.
