CC   -!- FUNCTION: Catalytic tRNA acetyltransferase subunit of the elongator
CC       complex which is required for multiple tRNA modifications, including
CC       mcm5U (5-methoxycarbonylmethyl uridine), mcm5s2U (5-
CC       methoxycarbonylmethyl-2-thiouridine), and ncm5U (5-carbamoylmethyl
CC       uridine) (By similarity). In the elongator complex, acts as a tRNA
CC       uridine(34) acetyltransferase by mediating formation of
CC       carboxymethyluridine in the wobble base at position 34 in tRNAs (By
CC       similarity). {ECO:0000250|UniProtKB:D5VRB9,
CC       ECO:0000250|UniProtKB:Q9H9T3}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=acetyl-CoA + H2O + S-adenosyl-L-methionine + uridine(34) in
CC         tRNA = 5'-deoxyadenosine + carboxymethyluridine(34) in tRNA + CoA + 2
CC         H(+) + L-methionine; Xref=Rhea:RHEA:61020, Rhea:RHEA-COMP:10407,

CC         Evidence={ECO:0000250|UniProtKB:D5VRB9};
CC   -!- COFACTOR:
CC       Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC         Evidence={ECO:0000250|UniProtKB:Q02908};
CC       Note=Binds 1 [4Fe-4S] cluster. The cluster is coordinated with 3
CC       cysteines and an exchangeable S-adenosyl-L-methionine.
CC       {ECO:0000250|UniProtKB:Q02908};
CC   -!- PATHWAY: tRNA modification; 5-methoxycarbonylmethyl-2-thiouridine-tRNA
CC       biosynthesis. {ECO:0000250|UniProtKB:Q9H9T3}.
CC   -!- SUBUNIT: Component of the elongator complex.
CC       {ECO:0000250|UniProtKB:Q9H9T3}.
CC   -!- SIMILARITY: Belongs to the ELP3 family. {ECO:0000305}.
CC   -!- CAUTION: The elongator complex was originally thought to play a role in
CC       transcription elongation. However, it is no longer thought to play a
CC       direct role in this process and its primary function is thought to be
CC       in tRNA modification. {ECO:0000250|UniProtKB:Q9H9T3}.
