Association of Mutations Identified in Xanthinuria with the Function and Inhibition Mechanism of Xanthine Oxidoreductase

open access: yesBiomedicines, 2021
Xanthine oxidoreductase (XOR) is an enzyme that catalyzes the two-step reaction from hypoxanthine to xanthine and from xanthine to uric acid in purine metabolism.

Exogenous application of xanthine and uric acid and nucleobase-ascorbate transporter MdNAT7 expression regulate salinity tolerance in apple

open access: yesBMC Plant Biology, 2021
Background Soil salinity is a critical threat to global agriculture. In plants, the accumulation of xanthine activates xanthine dehydrogenase (XDH), which catalyses the oxidation/conversion of xanthine to uric acid to remove excess reactive oxygen ...

Quantification of Uric Acid or Xanthine in Plant Samples

open access: yesBio-Protocol, 2015
We developed this protocol to assay and quantify the content of uric acid or xanthine in various tissues of Arabidopsis thaliana mutant lines with defective urate oxidase or xanthine dehydrogenase1 and in their complementation and suppressor lines (Hauck

Role of urate, xanthine oxidase and the effects of allopurinol in vascular oxidative stress [PDF]

open access: yes, 2009
Oxidative stress plays an important role in the progression of vascular endothelial dysfunction. The two major systems generating vascular oxidative stress are the NADPH oxidase and the xanthine oxidase pathways. Allopurinol, a xanthine oxidase inhibitor,

The Role of Xanthine Oxidase and Xanthine Dehydrogenase in Skin Ischemia [PDF]

open access: yesJournal of Surgical Research, 1994
The importance of sequential events which lead to skin necrosis has significant implications in trauma, vascular injury, and wound healing. In this series of experiments, we tested the hypothesis that xanthine oxidase (XO) activity was increased along an ischemic gradient of a skin flap and that the XO enzyme activity correlated with an increase in ...
