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 Rhea:RHEA-COMP:11727, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:17319, ChEBI:CHEBI:57287, ChEBI:CHEBI:57288,
CC ChEBI:CHEBI:57844, ChEBI:CHEBI:59789, ChEBI:CHEBI:65315,
CC ChEBI:CHEBI:74882; Evidence={ECO:0000250|UniProtKB:D5VRB9};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:61021;
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}.
