tRNA Hypermodification by mammalian ABH8 is described by C. He, T. Pan, and
co-workers in their Communication on page 8885 ff. The mammalian AlkB
homologue ABH8, containing an AlkB dioxygenase domain, catalyzes the oxidation
of mcm5U into (S)-mchm5U at the wobble position (uridine) in tRNA.
Isoprenoid Biosynthesis
Based on X-ray structure analyses of IspH proteins, a mechanism for the last step in
the non-mevalonate biosynthesis of isopentenyl diphosphate and dimethylallyl
diphosphate is describe M. Groll, T. Grwert et al. in their Minireview on
page 8802 ff.
Stable Cyclic Carbenes
In their Review on page 8810 ff. G. Bertrand et al. describe the synthesis and
characterization of stable cyclic carbenes. The stability, electronic properties,
coordination behavior, and catalytic activity of these complexes are also described.
Catalytic C H Functionalization
T. R. Cundari, T. H. Warren, and co-workers describe in their Communication on
page 8850 ff. a three-coordinate copper(II) amide that allows for the catalytic
amination of C(sp3) H bonds with unactivated primary and secondary amines.
