Binding Modes of Xanthine‐Derived Selective Allosteric Site Inhibitors of MTHFD2
ChemistryOpen, 2023 Methylenetetrahydrofolate dehydrogenase (MTHFD2) is a mitochondrial enzyme involved in 1 C metabolism that is upregulated in various cancer cells, but absent in normal proliferating cells. Xanthine derivatives are the first selective inhibitors of MTHFD2

Determination of Flavin Potential in Proteins by Xanthine/Xanthine Oxidase Method
Bio-Protocol, 2020 This protocol describes a simple xanthine/xanthine oxidase enzymatic equilibration method for determination of the redox potential of a flavin. As an example of the use of this method, we determine the reduction potential of the covalently bound FAD ...
