Identification
HMDB Protein ID HMDBP12322
Secondary Accession Numbers None
Name Probable tRNA sulfurtransferase
Synonyms
  1. Sulfur carrier protein ThiS sulfurtransferase
  2. Thiamine biosynthesis protein ThiI
  3. tRNA 4-thiouridine synthase
Gene Name THII
Protein Type Unknown
Biological Properties
General Function Not Available
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.
