Enzyme Information
| 2.1.1.228 | tRNA (guanine(37)-N(1))-methyltransferase. based on mapping to UniProt P43912 S-adenosyl-L-methionine + guanine(37) in tRNA = S-adenosyl-L-homocysteine + N(1)-methylguanine(37) in tRNA. -!- This enzyme is important for the maintenance of the correct reading frame during translation. -!- Unlike TrmD from Escherichia coli, which recognizes the G(36)pG(37) motif preferentially, the human enzyme (encoded by TRMT5) also methylates inosine at position 37. -!- Formerly EC 2.1.1.31. |
