CC -!- FUNCTION: Catalyzes the 2-thiolation of uridine at the wobble position
CC (U34) of mitochondrial tRNA(Lys), tRNA(Glu) and tRNA(Gln). Required for
CC the formation of 5-taurinomethyl-2-thiouridine (tm5s2U) of
CC mitochondrial tRNA(Lys), tRNA(Glu), and tRNA(Gln) at the wobble
CC position. ATP is required to activate the C2 atom of the wobble base.
CC {ECO:0000250|UniProtKB:Q12093}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=5-taurinomethyluridine(34) in tRNA + AH2 + ATP + S-sulfanyl-L-
CC cysteinyl-[protein] = 5-taurinomethyl-2-thiouridine(34) in tRNA + A +
CC AMP + diphosphate + H(+) + L-cysteinyl-[protein];
CC Xref=Rhea:RHEA:47040, Rhea:RHEA-COMP:10131, Rhea:RHEA-COMP:11726,
CC Rhea:RHEA-COMP:11732, Rhea:RHEA-COMP:11733, ChEBI:CHEBI:13193,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:17499, ChEBI:CHEBI:29950,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:33019, ChEBI:CHEBI:61963,
CC ChEBI:CHEBI:87171, ChEBI:CHEBI:87172, ChEBI:CHEBI:456215;
CC EC=2.8.1.14; Evidence={ECO:0000250|UniProtKB:Q12093};
CC -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000250}.
CC -!- MISCELLANEOUS: During the reaction, ATP is used to activate the C2 atom
CC of U34 by adenylation. After this, the persulfide sulfur on the
CC catalytic cysteine is transferred to the C2 atom of the wobble base
CC (U34) of mitochondrial tRNA(Lys), tRNA(Glu) and tRNA(Gln). The reaction
CC probably involves hydrogen sulfide that is generated from the
CC persulfide intermediate and that acts as nucleophile towards the
CC activated C2 atom on U34. Subsequently, a transient disulfide bond is
CC formed between the two active site cysteine residues (By similarity).
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the MnmA/TRMU family. {ECO:0000305}.
