C535A/C992R/C1316S | mutation in residues involved in conversion of xanthin dehydrogenase to xanthine oxidase by formation of disulfide bonds. Using guanidine-HCl, the mutant can be converted into the oxidase form | Rattus norvegicus |
General Stability | Organism |
---|---|
conversion of xanthine oxidoreductase from dehydrogenase to oxidase form occurs in the presence of guanidine-HCl or urea. Both forms are in a thermodynamic equilibrium that can be shifted by disruption of the stabilizing amino acid cluster with a denaturant | Rattus norvegicus |

Guanidine-HCl | conversion of xanthine oxidoreductase from dehydrogenase to oxidase form occurs in the presence of guanidine-HCl or urea. Both forms are in a thermodynamic equilibrium that can be shifted by disruption of the stabilizing amino acid cluster with a denaturant. Above 3 M gunandine-HCl, even xanthine oxidase activity decreases drastically, but the xanthine oxidase form treated with 1.5 M can be completely reconverted into xanthine dehydrogenase by dialysis | Bos taurus | |
Guanidine-HCl | conversion of xanthine oxidoreductase from dehydrogenase to oxidase form occurs in the presence of guanidine-HCl or urea. Both forms are in a thermodynamic equilibrium that can be shifted by disruption of the stabilizing amino acid cluster with a denaturant | Rattus norvegicus | |
Urea | conversion of xanthine oxidoreductase from dehydrogenase to oxidase form occurs in the presence of guanidine-HCl or urea. Both forms are in a thermodynamic equilibrium that can be shifted by disruption of the stabilizing amino acid cluster with a denaturant | Bos taurus |
