RA McClelland M., Sanderson E.K., Porwollik S., Spieth J., Clifton W.S., RA Fulton R., Chunyan W., Wollam A., Shah N., Pepin K., Bhonagiri V., RA Nash W., Johnson M., Thiruvilangam P., Wilson R.; RL Submitted (NOV-2007) to the EMBL/GenBank/DDBJ databases. 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 (By similarity). CC -!- CATALYTIC ACTIVITY: L-cysteine + 'activated' tRNA = L-serine + CC tRNA containing a thionucleotide. CC -!- CATALYTIC ACTIVITY: [IscS]-SSH + [ThiS]-COAMP = [IscS]-SH + CC [ThiS]-COSH + AMP. CC -!- PATHWAY: Cofactor biosynthesis; thiamine diphosphate biosynthesis. CC -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity). CC -!- SIMILARITY: Belongs to the thiI family. CC -!- SIMILARITY: Contains 1 rhodanese domain. CC -!- SIMILARITY: Contains 1 THUMP domain.
