'''tRNA methyltransferase''' (Trm) methylates specific positions on tRNA. tRNA methylation is a post-transcription modification.

S-adenosylornithine or sinefugin (SFG) is an inhibitor of the reaction. | '''tRNA methyltransferase''' (Trm) methylates specific positions on tRNA. tRNA methylation is a post-transcription modification.
