Stereoisomer-specific allosteric activation of xanthine oxidoreductase by shikonin and alkannin: mechanistic insights and hyperuricemia risk assessment
{{output}}
Xanthine oxidoreductase (XOR), the rate-limiting enzyme in uric acid metabolism, reversibly interconverts between dehydrogenase (XDH) and oxidase (XO) forms. Our previous study revealed allosteric activation of XOR by 1,4-naphthoquinones, highlighting their po... ...
