Enzyme Commission Primary Name: tRNA (guanine37-N1)-methyltransferase
Enzyme Commission Synonyms: TrmD, tRNA (m1G37) methyltransferase, transfer RNA (m1G37) methyltransferase, Trm5p, TRMT5, tRNA-(N1G37) methyltransferase, MJ0883 (gene name)
Enzyme Commission Summary:
This enzyme is important for the maintenance of the correct reading frame during translation. Unlike TrmD from Escherichia coli, which recognizes the G36pG37 motif preferentially, the human enzyme (encoded by TRMT5) also methylates inosine at position 37 [Brule04]. .
