| FUNCTION | Dual-specificity methyltransferase that catalyzes the formation of 5-methyluridine at position 54 (m5U54) in all tRNAs, and that of position 341 (m5U341) in tmRNA (transfer-mRNA). |
| CATALYTIC ACTIVITY | Reaction=S-adenosyl-L-methionine + uridine(54) in tRNA = 5- methyluridine(54) in tRNA + H(+) + S-adenosyl-L-homocysteine; Xref=Rhea:RHEA:42712, Rhea:RHEA-COMP:10167, Rhea:RHEA-COMP:10193, ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789, ChEBI:CHEBI:65315, ChEBI:CHEBI:74447; EC=2.1.1.35; |
| CATALYTIC ACTIVITY | Reaction=S-adenosyl-L-methionine + uridine(341) in tmRNA = 5- methyluridine(341) in tmRNA + H(+) + S-adenosyl-L-homocysteine; Xref=Rhea:RHEA:43612, Rhea:RHEA-COMP:10630, Rhea:RHEA-COMP:10631, ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789, ChEBI:CHEBI:65315, ChEBI:CHEBI:74447; |
| SIMILARITY | Belongs to the class I-like SAM-binding methyltransferase superfamily. RNA M5U methyltransferase family. TrmA subfamily. |
