Accession	PRU00952
Dates	14-DEC-2011 (Created) 14-DEC-2023 (Last updated, Version 14)
Data class	Domain;
Predictors	PROSITE; PS51620; SAM_TRM61
Name	tRNA (adenine(57)-N(1)/adenine(58)-N(1) or adenine(58)-N(1))-
Function	tRNA (adenine(58)-N(1))-methyltransferase (EC 2.1.1.220) is an enzyme that transfers a methyl group from S-adenosyl-L-methionine (SAM) to adenine(58) in tRNA to form N(1)-methyladenine(58) in tRNA and S-adenosyl-L- homocysteine. tRNA (adenine(57)-N(1)/adenine(58)-N(1))-methyltransferase (EC=2.1.1.219) is an enzyme that transfers a methyl group from the S-adenosyl-L-methionine (SAM) to adenine(57)/adenine(58) in tRNA to form N(1)-methyladenine57/N(1)- methyladenine58 in tRNA and S-adenosyl-L- homocysteine.
Scope(s)	Eukaryota
Example(s)	Q755M8 (TRM61_EREGS);
