Reactive oxygen species are generated by various biological systems, including NADPH oxidases, xanthine oxidoreductase, and mitochondrial respiratory enzymes, and contribute to many physiological and pathological phenomena. Mammalian xanthine dehydrogenase (XDH) can be converted to xanthine oxidase (XO), which produces both superoxide anion and ...

Xanthine oxidase and xanthine dehydrogenase
The FASEB Journal, 1995Xanthine oxidase and xanthine dehy‐drogenase are enzymes involved in the metabolism of purines and pyrimidines in various organisms. Their relationship to one another has been the subject of considerable debate, primarily because of their proposed roles in ischemia/reperfasion damage in tissues.

Xanthine calculi are uncommonly encountered stones. When they occur, they typically do so in association with inborn metabolic disorders such as hereditary xanthinuria or Lesch-Nyhan syndrome. They may also occur in association with states of profound hyperuricemia such as myeloproliferative disease after treatment with allopurinol.

The reactions of chloroperoxidase in the presence of xanthine/xanthine oxidase
Biochemical and Biophysical Research Communications, 1989Spectral data are presented which indicate that chloroperoxidase is converted to compound II during the reaction with superoxide/hydrogen peroxide generated in the xanthine/xanthine oxidase system. Upon completion of compound II formation, compound II returns back to the native state of chloroperoxidase without formation of detectable intermediates. It
