Featured article: An evolutionary encounter between tRNA and myelin maturation

tRNA splicing is an essential process in the maturation of eukaryotic pre-tRNA molecules. This study shows that tRNA healing enzymes from yeast and lancelet share structural and functional properties with members of the 2H-phosphoesterase superfamily, in particular the vertebrate myelin enzyme CNPase. While domain organization has been conserved, functions of the individual domains may have been altered or lost during evolution.

The conserved residues of Dnmt3a, R200 and R202, are essential for methylation activity. They are involved in positioning of the flipped target base and in creating and stabilizing of the transient covalent intermediate of the methylation reaction.
