Sulfurtransferase TusD

Gene

tusD

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Part of a sulfur-relay system required for 2-thiolation of 5-methylaminomethyl-2-thiouridine (mnm5s2U) at tRNA wobble positions. Accepts sulfur from TusA and transfers it in turn to TusE.1 Publication
