Human DNMT2 protein restores methylation in vitro to tRNAAsp from Dnmt2-deficient strains of mouse, Arabidopsis thaliana, and Drosophila melanogaster in a manner that is dependent on preexisting patterns of modified nucleosides. Unmodified tRNAAsp produced by in vitro transcription is not a substrate for DNMT2, which suggests that methylation is guided to cytosine38 by other modifications. Mannosylqueuosine is likely to be involved, because it is unique to tRNAAsp.
