Descrizione generale
Formerly E.C. 1.1.3.22
Applicazioni
Xanthine Oxidase from bovine milk has been used as a source for superoxide generation. It has also been used as a model enzyme in the internally calibrated electrochemical continuous enzyme assay (ICECEA).
Azioni biochim/fisiol
The isoflavanoid genistein was shown to inhibit xanthine oxidase at concentrations between 0.1-4.0 μM and then activate xanthine oxidase at concentrations higher than 5 μM.
Xanthine Oxidase acts as a potential biomarker for oxidative stress. It is also implicated in tissue and vascular injuries such as liver damage, inflammatory diseases and chronic heart failure.
Xanthine oxidase is a molybdenum-containing enzyme that is found in the cytosol, and may be strongly inhibited by flavonoids. It plays a vital role in the metabolism of some drugs, as well as purines and pyrimidines. It is also known to be a biological source of reactive oxygen species.
Definizione di unità
One unit will convert 1.0 μmole of xanthine to uric acid per min at pH 7.5 at 25 °C. Approx. 50% of the activity is obtained with hypoxanthine as substrate.
Stato fisico
Contains 0.5% sodium salicylate.
Risultati analitici
Protein determined by biuret

Generally, enzyme immobilization on nanoparticles leads to nano-conjugates presenting partially preserved, or even absent, biological properties. Notwithstanding, recent research demonstrated that the coupling to nanomaterials can improve the activity of immobilized enzymes. Herein, xanthine oxidase (XO) was immobilized by self-assembly
