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). May act by
CC forming a heterodimer with NCS6 that ligates sulfur from
CC thiocarboxylated URM1 onto the uridine of tRNAs at wobble position.
CC Prior mcm(5) tRNA modification by the elongator complex is required for
CC 2-thiolation. May also be involved in protein urmylation.
CC {ECO:0000256|HAMAP-Rule:MF_03054}.
CC -!- PATHWAY: tRNA modification; 5-methoxycarbonylmethyl-2-thiouridine-tRNA
CC biosynthesis. {ECO:0000256|HAMAP-Rule:MF_03054}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_03054}.
CC -!- SIMILARITY: Belongs to the CTU2/NCS2 family. {ECO:0000256|HAMAP-
CC Rule:MF_03054}.
