CC -!- FUNCTION: Catalyzes the ATP-dependent transfer of a sulfur to tRNA CC to produce 4-thiouridine in position 8 of tRNAs, which functions CC as a near-UV photosensor. Also catalyzes the transfer of sulfur to CC the sulfur carrier protein ThiS, forming ThiS-thiocarboxylate. CC This is a step in the synthesis of thiazole, in the thiamine CC biosynthesis pathway. The sulfur is donated as persulfide by IscS. CC {ECO:0000256|HAMAP-Rule:MF_00021, ECO:0000256|SAAS:SAAS00848766}.
