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;
