Neomorphic enzymatic activity

WebIDH1 and IDH2 mutant enzymes gain neomorphic enzymatic activity, converting NADPH and αKG to NADP+ and D-2HG. D-2HG acts as a weak competitive inhibitor of αKG-dependent dioxygenases. αKG-dependent dioxygenases are involved in various cellular processes such as hypoxia, angiogenesis, maturation of collagens of the extracellular … WebOct 14, 2012 · These mutants acquire a neomorphic enzymatic activity that enables the conversion of αKG to 2HG, which can impair normal epigenetic regulation through competitive inhibition of various αKG-dependent dioxygenases, including TET2 DNA hydroxylases and JmjC histone demethylases.
