The Ta0836 gene product is T. acidophilum Trm5. (A) 10 µg of the purified Ta0836 gene product was analyzed by 15% SDS-PAGE. The gel was stained with Coomassie Brilliant Blue; (B) The tRNALeuUAG transcript was methylated by the Ta0836 gene product and then the generated methylated nucleotide was analyzed by 2D-TLC; (C) The methyl group acceptance activities of the wild-type tRNALeuUAG transcript (lane 1) and the mutant tRNALeuUAG transcript (lane 2), in which G37 was replaced by A, were investigated. The transcripts were individually incubated with the Ta0836 gene product and 14C-AdoMet, and then separated by 10% PAGE (7 M urea). The gel was stained with methylene blue (left panel) and the autoradiogram of the same gel was taken (right panel).
