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:0000256|HAMAP-Rule:MF_00021}.
