Protein
tRNA sulfurtransferase
Gene
thiI, Pfl01_0346
Organism
Pseudomonas fluorescens (strain Pf0-1)
Status
Reviewed - Annotation score: 4 out of 5 - Protein inferred from homologyi

Functioni

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 By similarity.UniRule annotation

Catalytic activityi

L-cysteine + 'activated' tRNA = L-serine + tRNA containing a thionucleotide.UniRule annotation
[IscS]-SSH + [ThiS]-COAMP = [IscS]-SH + [ThiS]-COSH + AMP.UniRule annotation
