tRNA (5-carboxymethoxyuridine(34)-5-O)-methyltransferase activity
trna (5-carboxymethoxyuridine(34)-5-o)-methyltransferase activity
5-carboxymethoxyuridine(34) in tRNA + S-adenosyl-L-methionine = 5-methoxycarbonylmethoxyuridine(34) in tRNA + S-adenosyl-L-homocysteine
5-carboxymethoxyuridine(34) in trna + s-adenosyl-l-methionine = 5-methoxycarbonylmethoxyuridine(34) in trna + s-adenosyl-l-homocysteine
