Display the reaction diagram Show all sequences 2.8.1.B3more ThiI is responsible for the formation of the modified base 4-thiouridine found at position 8 in some prokaryotic tRNAs. This base acts as a sensitive trigger for the response mechanism to UV exposure, providing protection against its damaging effects Bacillus anthracis ? - ?
Display the reaction diagram Show all sequences 2.8.1.B3more the enzyme also catalyzes the transfer of sulfur from thiosulfate to cyanide (EC 2.8.1.1) Escherichia coli ? - ?
Display the reaction diagram Show all sequences 2.8.1.B3more the RLD-containing protein ThiI also acts as a sulfur carrier for generating ThiS-COSH. ThiI accepts a persulfide sulfur from IscS, then transfers the sulfur for thiocarboxylate formation to the C-terminus of ThiS which is catalyzed by ThiF Escherichia coli ? - ?
Display the reaction diagram Show all sequences 2.8.1.B3more the enzyme is not able to enhance cysteine desulfurase NifZ activity of sulfide or alanine formation Bacillus subtilis ? - ?
Display the reaction diagram Show all sequences 2.8.1.B3more three domains of ThiI are essential for the thiolation of tRNA: a THUMP domain that binds tRNA, an AANH domain that activates the uridine residue by adenylylation, and a rhodanese domain that transfers sulfur to the activated uridine residue. Only the rhodanese domain of the ThiI protein is required for a key thiolation reaction in the synthesis of thiamine, while the other two domains (THUMP and AANH) are dispensable Escherichia coli ? - ?
Display the reaction diagram Show all sequences 2.8.1.B3more the enzyme also displays an ATP diphosphatase activity for the adenylation of uridine Escherichia coli ? - ?
Display the reaction diagram Show all sequences 2.8.1.B3more the enzyme is not able to enhance cysteine desulfurase NifZ activity of sulfide or alanine formation Bacillus subtilis PS832 ? - ?
Display the reaction diagram Show all sequences 2.8.1.B3sulfide + adenylated-tRNA-uridine(position8) sulfide is able to replace IscS/cysteine as a substrate for 4-thiouridine synthesis Escherichia coli tRNA-4-thiouridine(position8) + ? - ?
Display the reaction diagram Show all sequences 2.8.1.B3sulfurtransferase IscS-SSH + adenylated-tRNA-uridine(position8) - Bacillus subtilis sulfurtransferase IscS-SH + tRNA-4-thiouridine(position8) + AMP - ?
