Enzyme Information

2.1.1.220
tRNA (adenine(58)-N(1))-methyltransferase.
based on mapping to UniProt Q8GBB2
S-adenosyl-L-methionine + adenine(58) in tRNA = S-adenosyl-L-homocysteine + N(1)-methyladenine(58) in tRNA.
-!- The enzyme specifically methylates adenine(58) in tRNA. -!- The methylation of A(58) is critical for maintaining the stability of initiator tRNA(Met) in yeast. -!- Formerly EC 2.1.1.36.
