CC   -!- FUNCTION: Plays a central role in 2-thiolation of mcm(5)S(2)U at tRNA
CC       wobble positions of tRNA(Lys), tRNA(Glu) and tRNA(Gln). Directly binds
CC       tRNAs and probably acts by catalyzing adenylation of tRNAs, an
CC       intermediate required for 2-thiolation. It is unclear whether it acts
CC       as a sulfurtransferase that transfers sulfur from thiocarboxylated URM1
CC       onto the uridine of tRNAs at wobble position. {ECO:0000255|HAMAP-
CC       Rule:MF_03053}.
CC   -!- PATHWAY: tRNA modification; 5-methoxycarbonylmethyl-2-thiouridine-tRNA
CC       biosynthesis. {ECO:0000255|HAMAP-Rule:MF_03053}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03053}.
CC   -!- SIMILARITY: Belongs to the TtcA family. CTU1/NCS6/ATPBD3 subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_03053}.
