Oxidative Demethylation of DNA and RNA Mediated by Non-Heme Iron-Dependent Dioxygenases
Do you like metalcore? AlkB family and TET proteins share a common metal core coordinated with a conserved HxD/E···H motif and α-KG. These dioxygenases perform a wide range oxidative demethylation functions in biology: AlkB, ALKBH2, and ALKBH3 demethylate m1 A and m3C; FTO and ALKBH5 reverse m6 A modification; and TET proteins can oxidize 5 mC to 5 hmC, 5fC, and 5caC.

Angewandte Chemie 29/2014: Four Stars
In this issue, S.-L. Suraru and F. Würthner review syntheses of functional naphthalene diimides. What strategies are the most promising? In a Minireview, K. A. Jørgensen et al. discuss asymmetric organocatalytic epoxidations. The Highlight deals with the preparation of CO2/diene copolymers (G. Fiorani and A. W. Kleij).
In the Communications section, M. J. Bojdys et al. present a two-dimensional semiconductor: triazine-based graphitic carbon nitride (see picture). M. Scheer et al. succeeded in the selective functionalization of P4 by metal-mediated C–P bond formation. Y. Cao et al. describe a gold-catalyzed hydrogenative coupling of nitroarenes to synthesize aromatic azo compounds, and J. W. Bode et al. show how to prepare potassium acyltrifluoroborates in just one step.
Dating by Electrode
Voltammetry of microparticles used to date archeological artifacts made of copper and bronze
How can the age of archeological objects be determined if the well-established carbon dating method does not apply, for example for metal objects? Spanish and Portuguese scientists have now introduced a technique for dating artifacts made of copper and bronze. Presented in the journal Angewandte Chemie, their electroanalytical method is based on the voltammetry of microparticles. It compares various corrosion products that form over long periods of time and works with only a few nanograms of material so it causes almost no damage.
