Display the reaction diagram Show all sequences 2.8.1.B3sulfurtransferase IscS-SSH + adenylated-tRNA-uridine(position8) the biosynthesis of 4-thiouridine in Escherichia coli tRNA requires the action of both the thiamin pathway enzyme ThiI and the cysteine desulfurase IscS. IscS catalyzes sulfur transfer from L-cysteine to ThiI, which utilizes MgATP2- to activate uridine 8 in tRNA and transfers sulfur to give s4U. Outside of the modified uridine 8, there is no primary sequence requirement for substrate recognition. However, the secondary and tertiary structure restrictions appear sufficient to explain why s4U modification is limited in the cell to tRNA Escherichia coli sulfurtransferase IscS-SH + tRNA-4-thiouridine(position8) + AMP - ?
