CC -!- FUNCTION: Catalyzes the 2-thiolation of uridine at the wobble position
CC (U34) of tRNA(Lys), tRNA(Glu) and tRNA(Gln), leading to the formation
CC of s(2)U34, the first step of tRNA-mnm(5)s(2)U34 synthesis. Sulfur is
CC provided by IscS, via a sulfur-relay system. Binds ATP and its
CC substrate tRNAs. {ECO:0000256|HAMAP-Rule:MF_00144}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=AH2 + ATP + S-sulfanyl-L-cysteinyl-[protein] + uridine(34) in
CC tRNA = 2-thiouridine(34) in tRNA + A + AMP + diphosphate + H(+) + L-
CC cysteinyl-[protein]; Xref=Rhea:RHEA:47032, Rhea:RHEA-COMP:10131,

CC ChEBI:CHEBI:456215; EC=2.8.1.13;
CC Evidence={ECO:0000256|ARBA:ARBA00001042, ECO:0000256|HAMAP-
CC Rule:MF_00144};
CC -!- SUBUNIT: Interacts with TusE. {ECO:0000256|HAMAP-Rule:MF_00144}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00144}.
CC -!- SIMILARITY: Belongs to the MnmA/TRMU family. {ECO:0000256|HAMAP-
CC Rule:MF_00144}.
