Sulfur carrier protein TusA (IPR022931)

Short name: Sulphur_carrier_TusA

Overlapping homologous superfamilies

Family relationships



This entry represents the TusA family of sulfur carrier proteins. TusA (also known as SirA, UvrY and YhhP) belongs to a group of five proteins (TusA-E) which together are responsible for 2-thiouridylation of 5-methylaminomethyl-2-thiouridine at tRNA wobble positions. TusA accepts sulfur from cysteine desulfurase IscS and transfers it in turn to TusD [PMID: 16387657].
