CC   -!- FUNCTION: Catalyzes the ATP-dependent transfer of a sulfur to tRNA to
CC       produce 4-thiouridine in position 8 of tRNAs, which functions as a
CC       near-UV photosensor. Also catalyzes the transfer of sulfur to the
CC       sulfur carrier protein ThiS, forming ThiS-thiocarboxylate. This is a
CC       step in the synthesis of thiazole, in the thiamine biosynthesis
CC       pathway. The sulfur is donated as persulfide by IscS.
CC       {ECO:0000255|HAMAP-Rule:MF_00021}.
