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   -!- 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.
