Mutant isocitrate dehydrogenase 1/2-driven D-2-hydroxyglutarate (D2HG) and hypoxia-induced L-2-hydroxyglutarate (L2HG) are known to non-covalently inhibit α-ketoglutarate-dependent enzymes in several cancer types. Now, through use of chemical proteomics, stereoselective protein O-2-hydroxyglutarylation by D2HG or L2HG has been characterized as a distinct oncometabolite-induced post-translational modification with evidence for crosstalk with kinase activity.
