there are 19 unique tRNA species that contain a G at position 9 in yeast, and whose fully modified sequence is known, only 9 of these tRNA species are modified with m1G9 in wild-type cells. The in vitro methylation activity of yeast Trm10 is not sufficient to explain the observed pattern of modification in vivo, as additional tRNA species are substrates for Trm10 m1G9 methyltransferase activity, substrate specificity analysis in vivo, overview |

substrate specificity analysis and comparison of hTRMT10A and hTRMT10B enzymes, overview. hTRMT10A and hTRMT10B catalyze methylation of different tRNA substrates. hTRMT10A displays robust activity on every tested G9-containing tRNA from either humans or Saccharomyces cerevisiae, similar to Saccharomyces cerevisiae ScTrm10. hTRMT10B, and not hTRMT10A, is indeed capable of catalyzing m1A9 methylation on tRNAAsp in vitro, while hTRMT10B has the sole responsibility for generating the m1A9 modification. hTRMT10A displays higher in vitro catalytic rates than hTRMT10B |
