CC -!- FUNCTION: Catalyzes the methylation of 5-carboxymethoxyuridine (cmo5U)
CC to form 5-methoxycarbonylmethoxyuridine (mcmo5U) at position 34 in
CC tRNAs. {ECO:0000256|HAMAP-Rule:MF_02057}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=5-carboxymethoxyuridine(34) in tRNA + S-adenosyl-L-methionine
CC = 5-methoxycarbonylmethoxyuridine(34) in tRNA + S-adenosyl-L-
CC homocysteine; Xref=Rhea:RHEA:54080, Rhea:RHEA-COMP:13383, Rhea:RHEA-
CC COMP:13781, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789, ChEBI:CHEBI:136879,
CC ChEBI:CHEBI:138053; Evidence={ECO:0000256|HAMAP-Rule:MF_02057};
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. CmoM family. {ECO:0000256|HAMAP-Rule:MF_02057}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_02057}.
