Enzyme Information
| 2.1.1.219 |
tRNA (adenine(57)-N(1)/adenine(58)-N(1))-methyltransferase.
based on mapping to UniProt Q9V1J7
2 S-adenosyl-L-methionine + adenine(57)/adenine(58) in tRNA = 2 S-adenosyl-L-homocysteine + N(1)-methyladenine(57)/N(1)- methyladenine(58) in tRNA.
-!- The enzyme catalyzes the formation of N(1)-methyladenine at two adjacent positions (57 and 58) in the T-loop of certain tRNAs (e.g. tRNA(Asp)). -!- Methyladenosine at position 57 is an obligatory intermediate for the synthesis of methylinosine, which is commonly found at position 57 of archaeal tRNAs. -!- Formerly EC 2.1.1.36.
