XDH (Xanthine Dehydrogenase) is a Protein Coding gene. Diseases associated with XDH include Xanthinuria, Type I and Xanthinuria. Among its related pathways are Doxorubicin Pathway, Pharmacokinetics and Metabolism. XDH belongs to the group of molybdenum-containing hydroxylases involved in the oxidative metabolism of purines. The encoded protein has been identified as a moonlighting protein based on its ability to perform mechanistically distinct functions. XDH can be converted to xanthine oxidase by reversible sulfhydryl oxidation or by irreversible proteolytic modification. Defects in XDH cause xanthinuria, may contribute to adult respiratory stress syndrome, and may potentiate influenza infection through an oxygen metabolite-dependent mechanism.
