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:0000255|HAMAP-Rule:MF_01885}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=cytidine(34) in tRNA + S-adenosyl-L-methionine = 2'-O-
CC         methylcytidine(34) in tRNA + H(+) + S-adenosyl-L-homocysteine;

CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01885}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|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:0000255|HAMAP-Rule:MF_01885}.
CC   -!- CAUTION: Possibly identical to gltE. {ECO:0000305}.
