Trm5 catalyzes the methyl transfer from S-adenosyl methionine (AdoMet) to N1 of G37. This domain, also known as the D1 domain, contacts the ter ...	This is the N-terminal domain of tRNA methyltransferase 5 (Trm5) present in Methanocaldococcus jannaschii. Trm5 catalyzes the methyl transfer from S-adenosyl methionine (AdoMet) to N1 of G37. This domain, also known as the D1 domain, contacts the tertiary core (elbow) region of the tRNA L shape in a ternary complex of the enzyme with tRNA and AdoMet [1].	Domain
