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:0000256|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 COMP:13383, ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:134278,

CC Rule:MF_01590};
CC -!- SUBUNIT: Homotetramer. {ECO:0000256|HAMAP-Rule:MF_01590}.
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. CmoB family. {ECO:0000256|HAMAP-Rule:MF_01590}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
