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}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[ThiI sulfur-carrier protein]-S-sulfanyl-L-cysteine + a
CC uridine in tRNA + ATP + H(+) + 2 reduced [2Fe-2S]-[ferredoxin] =
CC [ThiI sulfur-carrier protein]-L-cysteine + a 4-thiouridine in tRNA +
CC AMP + diphosphate + 2 oxidized [2Fe-2S]-[ferredoxin];
