Histone methylation and demethylation. (A) Histones are methylated by KMTs, which require SAM as a cosubstrate. Two different classes of KDMs can remove a methyl group. LSD1/2 require FAD as an electron acceptor. The JmjC domain-containing KDMs use αKG as a cosubstrate. Fumarate, succinate, and R-2HG are competitive inhibitors. (FADH2) FAD, reduced; (Me) methyl. (B) Schematic representation of folate-mediated one-carbon metabolism in the cytosol. (hCys) Homocysteine; (Met) methionine; (NADP+) NAD phosphate.
