  • Some proteins are degraded by a process called the N-end rule, in which a non-templated amino acid is added to the amino terminus as a marker for degradation. A set of crystal structures of the enzyme that promotes transfer of the amino acid along with the charged donor tRNA is solved in the presence or absence of target peptide. The results reveal that peptide bond formation occurs differently than on the ribosome.

  • Euryarchaeal ArcS alone cannot produce G+-containing tRNA but works as a lysine transferase to produce a lysine adduct intermediate, which finally forms G+-containing tRNA in the presence of a newly identified SAM enzyme, RaSEA.

  • This review focused on the various polymers composed of trimethylene carbonate (TMC) units and ethylene glycol (EG) units. Poly(TMC) is a biodegradable polymer that is used in biomedical materials. It has been reported that its combination with oligo(EG) and poly(EG) would offer a useful approach. In addition, monomer design and polymer reactions are available. These polymers, including TMC and EG units, are useful in preparing various nanostructures and they have the potential for application in biomedical materials.
