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:0000255|HAMAP-Rule:MF_03054}.
CC   -!- PATHWAY: tRNA modification; 5-methoxycarbonylmethyl-2-thiouridine-tRNA
CC       biosynthesis. {ECO:0000255|HAMAP-Rule:MF_03054}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03054}.
CC   -!- SIMILARITY: Belongs to the CTU2/NCS2 family. {ECO:0000255|HAMAP-
CC       Rule:MF_03054}.
