CC -!- FUNCTION: Catalyzes the methylation of 5-carboxymethyl uridine to 5-
CC methylcarboxymethyl uridine at the wobble position of the anticodon
CC loop in tRNA via its methyltransferase domain. Catalyzes the last step
CC in the formation of 5-methylcarboxymethyl uridine at the wobble
CC position of the anticodon loop in target tRNA. Has a preference for
CC tRNA(Arg) and tRNA(Glu), and does not bind tRNA(Lys). Binds tRNA and
CC catalyzes the iron and alpha-ketoglutarate dependent hydroxylation of
CC 5-methylcarboxymethyl uridine at the wobble position of the anticodon
CC loop in tRNA via its dioxygenase domain, giving rise to 5-(S)-
CC methoxycarbonylhydroxymethyluridine; has a preference for tRNA(Gly).
CC Required for normal survival after DNA damage. May inhibit apoptosis
CC and promote cell survival and angiogenesis (By similarity).
CC {ECO:0000250|UniProtKB:Q96BT7}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=5-(carboxymethyl)uridine(34) in tRNA + S-adenosyl-L-methionine
CC = 5-(2-methoxy-2-oxoethyl)uridine(34) in tRNA + S-adenosyl-L-
