Identification |
Name: |
tRNA sulfurtransferase |
Synonyms: |
- Sulfur carrier protein ThiS sulfurtransferase
- Thiamine biosynthesis protein thiI
- tRNA 4-thiouridine synthase
|
Gene Name: |
thiI |
Enzyme Class: |
|
Biological Properties |
General Function: |
Involved in RNA binding |
Specific Function: |
Catalyzes the ATP-dependent transfer of a sulfur to tRNA to produce 4-thiouridine in position 8 of tRNAs, which functions as a near-UV photosensor. Also catalyzes the transfer of sulfur to the sulfur carrier protein ThiS, forming ThiS-thiocarboxylate. This is a step in the synthesis of thiazole, in the thiamine biosynthesis pathway. The sulfur is donated as persulfide by iscS |
