    Histone demethylase LSD1 regulates transcription by demethylating Lys(4) of histone H3. The crystal structure of the enzyme in complex with CoREST and a substrate-like peptide inhibitor highlights an intricate network of interactions and a folded conformation of the bound peptide. The core of the peptide structure is formed by Arg(2), Gln(5), and Ser(10), which are engaged in specific intramolecular H-bonds. Several charged side chains on the surface of the substrate-binding pocket establish electrostatic interactions with the peptide. The three-dimensional structure predicts that methylated Lys(4) binds in a solvent inaccessible position in front of the flavin cofactor. This geometry is fully consistent with the demethylation reaction being catalyzed through a flavin-mediated oxidation of the substrate amino-methyl group. These features dictate the exquisite substrate specificity of LSD1 and provide a structural framework to explain the fine tuning of its catalytic activity and the active role of CoREST in substrate recognition.
