CC   -!- FUNCTION: Catalyzes carboxymethyl transfer from carboxy-S-adenosyl-L-
CC       methionine (Cx-SAM) to 5-hydroxyuridine (ho5U) to form 5-
CC       carboxymethoxyuridine (cmo5U) at position 34 in tRNAs.
CC       {ECO:0000255|HAMAP-Rule:MF_01590}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=5-hydroxyuridine(34) in tRNA + carboxy-S-adenosyl-L-methionine
CC         = 5-carboxymethoxyuridine(34) in tRNA + H(+) + S-adenosyl-L-
CC         homocysteine; Xref=Rhea:RHEA:52848, Rhea:RHEA-COMP:13381, Rhea:RHEA-

CC   -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_01590}.
CC   -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC       superfamily. CmoB family. {ECO:0000255|HAMAP-Rule:MF_01590}.
