Protein Domain : IPR020536

Type:  Domain Name:  Thil, AANH domain
Description:  tRNA sulfurtransferase ThiI catalyses 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 [, , ]. In some bacteria, ThiI is a bifunctional enzyme required for the synthesis of both the 4-thiouridine modification in tRNA and the thiazole moiety in the thiamine biosynthesis pathway [].Three domains of ThiI are essential for the thiolation of tRNA: a THUMP domain that binds tRNA (see ) [], an AANH domain that activates the uridine residue by adenylylation [], and a rhodanese domain that transfers sulfur to the activated uridine residue []. Neither the THUMP nor the AANH domain of ThiI are essential for thiamine synthesis, only the rhodanese domain is necessary for synthesis of the thiazole moiety of thiamine [].This entry represents the AANH domain. Short Name:  ThiI_AANH
