In humans, the xanthine oxidoreductase enzymes are known to catalyze the final two steps of purine metabolism by converting hypoxanthine successively to xanthine and uric acid. Xanthine oxidoreductase also metabolizes a wide variety of drugs in vivo, and activates a number of antiviral prodrugs of clinical importance. Therefore, understanding the reaction mechanism of this enzyme is of prime importance in furthering our understanding of enzyme-drug interactions. In order to provide a greater understanding on the reaction mechanism, theoretical and enzymatic spectroscopic experimental approaches have been utilized. The theoretical approaches were used to elucidate the electronic structure and geometry of the …
