CC   -!- FUNCTION: Specifically catalyzes the AdoMet-dependent 2'-O-ribose
CC       methylation of cytidine at position 56 in tRNAs. {ECO:0000255|HAMAP-
CC       Rule:MF_00077}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=cytidine(56) in tRNA + S-adenosyl-L-methionine = 2'-O-
CC         methylcytidine(56) in tRNA + H(+) + S-adenosyl-L-homocysteine;
