CC -!- FUNCTION: Methylates the ribose at the nucleotide 34 wobble position in
CC the two leucyl isoacceptors tRNA(Leu)(CmAA) and tRNA(Leu)(cmnm5UmAA).
CC Catalyzes the methyl transfer from S-adenosyl-L-methionine to the 2'-OH
CC of the wobble nucleotide. {ECO:0000256|HAMAP-Rule:MF_01885}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=5-carboxymethylaminomethyluridine(34) in tRNA(Leu) + S-
CC adenosyl-L-methionine = 5-carboxymethylaminomethyl-2'-O-
CC methyluridine(34) in tRNA(Leu) + H(+) + S-adenosyl-L-homocysteine;

CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01885}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01885}.
CC -!- SIMILARITY: Belongs to the class IV-like SAM-binding methyltransferase
CC superfamily. RNA methyltransferase TrmH family. TrmL subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_01885}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01885}.
