General rule information [?]

Accession PRU00952
Dates 14-DEC-2011 (Created)
21-NOV-2019 (Last updated, Version 10)
Data class Domain
Predictors PROSITE; PS51620; SAM_TRM61
Names tRNA (adenine(57)-N(1)/adenine(58)-N(1) or adenine(58)-N(1))-; methyltransferase
Function tRNA (adenine(58)-N(1))-methyltransferase (EC 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= 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.
