Hypomodification of the taurine modification in a patient with pathogenic mutations in GTPBP3. XICs of anticodon-containing RNase T1-digested fragments with different modifications of mt-tRNAs for Leu(UUR) (A), Trp (B), Gln (C), Glu (D) and Lys (E), isolated from neonatal human dermal fibroblast (NHDF) (left panels) and patient fibroblasts (right panels). Sequence of the detected fragment, with its m/z value and charge state, is indicated on the right. Relative frequencies of τm5(s2)U in the patient sample are indicated in the bottom chromatograms. n.d., not detected. ms2i6A, 2-methylthio-N6-isopentenyladenosine; i6A, N6-isopentenyladenosine.
