TRMT6, also known as tRNA methyltransferase 6 homolog, is an enzyme that highlights the significance of post-transcriptional modification in transfer RNA (tRNA). TRMT6 is part of the class I-like SAM (S-adenosylmethionine)-dependent methyltransferase superfamily and facilitates the methylation of specific nucleotides within tRNA molecules. This modification, especially at the wobble position of adenosine residues, is essential for the precise and efficient translation of mRNA into protein, aiding the stabilization of codon-anticodon pairing and ensuring accuracy during protein synthesis.
