Comments [?]

FUNCTION	Catalyzes carboxymethyl transfer from carboxy-S-adenosyl-L- methionine (Cx-SAM) to 5-hydroxyuridine (ho5U) to form 5- carboxymethoxyuridine (cmo5U) at position 34 in tRNAs.
CATALYTIC ACTIVITY	Reaction=5-hydroxyuridine(34) in tRNA + carboxy-S-adenosyl-L-methionine = 5-carboxymethoxyuridine(34) in tRNA + H(+) + S-adenosyl-L- homocysteine; Xref=Rhea:RHEA:52848, Rhea:RHEA-COMP:13381, Rhea:RHEA- COMP:13383, ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:134278, ChEBI:CHEBI:136877, ChEBI:CHEBI:136879;
case <OC:Pseudomonadota>
SUBUNIT	Homotetramer.
end case
SIMILARITY	Belongs to the class I-like SAM-binding methyltransferase superfamily. CmoB family.
