tRNA fragment coverage for the Dnmt2 substrates tRNA(Gly) and tRNA(Asp), and the non-substrate tRNA(Ser) in bone marrow, as determined by deep sequencing. Wild-type coverage is represented in red, and Dnmt2−/− coverage is indicated in blue. The plots illustrate the specific increase of 5′-halves from tRNA-Gly and 3′-halves from tRNA-Asp fragments in Dnmt2 mutants.
