CC -!- FUNCTION: Catalyzes the last two steps in the biosynthesis of 5-
CC methylaminomethyl-2-thiouridine (mnm(5)s(2)U) at the wobble position
CC (U34) in tRNA. Catalyzes the FAD-dependent demodification of
CC cmnm(5)s(2)U34 to nm(5)s(2)U34, followed by the transfer of a methyl
CC group from S-adenosyl-L-methionine to nm(5)s(2)U34, to form
CC mnm(5)s(2)U34. {ECO:0000255|HAMAP-Rule:MF_01102}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=5-aminomethyl-2-thiouridine(34) in tRNA + S-adenosyl-L-
CC methionine = 5-methylaminomethyl-2-thiouridine(34) in tRNA + H(+) +
CC S-adenosyl-L-homocysteine; Xref=Rhea:RHEA:19569, Rhea:RHEA-

CC ChEBI:CHEBI:57856, ChEBI:CHEBI:59789, ChEBI:CHEBI:74454,
CC ChEBI:CHEBI:74455; EC=2.1.1.61; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01102};
CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01102};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01102}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the methyltransferase
CC superfamily. tRNA (mnm(5)s(2)U34)-methyltransferase family.
CC {ECO:0000255|HAMAP-Rule:MF_01102}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the DAO family.
