Native Xanthine Dehydrogenase from Bovine milk

inquiry

Cat No.

NATE-1065

Description

Xanthine oxidoreductase (XOR) catalyzes the formation of uric acid from hypoxanthine and xanthine, last two steps of purine catabolism. The mammalian enzyme is synthesized as a xanthine dehydrogenase form (XDH, EC 1.17.1.4), which uses NAD as the electron acceptor, but is converted into an xanthine oxidase form (XO, EC 1.1.3.22) by reversible (through sulfhydryl group oxidation) or irreversible (proteolysis) manner. Since most industrial protocols of XOR purification includes proteolysis step, commercial XOR enzyme is available only as oxidase form unable to use NAD as a an electron acceptor.
