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. Prior mcm(5) tRNA
CC modification by the elongator complex is required for 2-thiolation. May
CC also be involved in protein urmylation. {ECO:0000256|HAMAP-
CC Rule:MF_03053}.
CC -!- PATHWAY: tRNA modification; 5-methoxycarbonylmethyl-2-thiouridine-tRNA
CC biosynthesis. {ECO:0000256|HAMAP-Rule:MF_03053}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_03053}.
CC -!- SIMILARITY: Belongs to the TtcA family. CTU1/NCS6/ATPBD3 subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_03053}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
