WebLeukemia-associated IDH1/IDH2 mutations confer the neomorphic activity of reducing αKG to the oncometabolite 2-hydroxyglutarate. ... an AOL domain, essential for enzymatic activity (the AOL domain has two lobes, one forming a noncovalent FAD-binding site and the other a substrate-binding and -recognition site), and a SWIRM domain, ... WebJan 22, 2024 · IDH mutants acquire a neomorphic enzymatic activity that catalyzes the reduction of α-KG to 2-hydroxyglutarate (2-HG) (Dang et al. 2009; Ward et al. 2010). 2-HG competitively inhibits α-KG-dependent enzymes and causes epigenomic reprogramming thus contributing to tumorigenesis (Lu et al. 2012; Turcan et al. 2024).
