TRNA (adenine58-N1)-methyltransferase (EC 2.1.1.220, tRNA m1A58 methyltransferase, tRNA (m1A58) methyltransferase, TrmI, tRNA (m1A58) Mtase, Rv2118cp, Gcd10p-Gcd14p, Trm61p-Trm6p) is an enzyme with systematic name S-adenosyl-L-methionine:tRNA (adenine58-N1)-methyltransferase.[1][2][3] This enzyme catalyses the following chemical reaction
- S-adenosyl-L-methionine + adenine58 in tRNA S-adenosyl-L-homocysteine + N1-methyladenine58 in tRNA
The enzyme specifically methylates adenine58 in tRNA.
