Crystal structure of a 4-thiouridine synthetase - RNA complex with bound ATP
Template:ABSTRACT PUBMED 24705700
Function
[THII_THEMA] 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).
About this Structure
4kr7 is a 4 chain structure. Full crystallographic information is available from OCA.
