FUNCTIONCatalyzes the methylation of 5-hydroxyuridine (ho5U) to form 5-methoxyuridine (mo5U) at position 34 in tRNAs.
CATALYTIC ACTIVITY Reaction=5-hydroxyuridine(34) in tRNA + S-adenosyl-L-methionine = 5- methoxyuridine(34) in tRNA + H(+) + S-adenosyl-L-homocysteine; Xref=Rhea:RHEA:60524, Rhea:RHEA-COMP:13381, Rhea:RHEA-COMP:15591, ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789, ChEBI:CHEBI:136877, ChEBI:CHEBI:143860;
SIMILARITYBelongs to the class I-like SAM-binding methyltransferase superfamily. Cation-dependent O-methyltransferase family.
