CC   -!- FUNCTION: Sulfur carrier protein involved in sulfur trafficking in the
CC       cell. Part of a sulfur-relay system required for 2-thiolation during
CC       synthesis of 2-thiouridine of the modified wobble base 5-
CC       methylaminomethyl-2-thiouridine (mnm(5)s(2)U) in tRNA. Interacts with
CC       IscS and stimulates its cysteine desulfurase activity. Accepts an
CC       activated sulfur from IscS, which is then transferred to TusD, and thus
CC       determines the direction of sulfur flow from IscS to 2-thiouridine
CC       formation. Also appears to be involved in sulfur transfer for the
CC       biosynthesis of molybdopterin. {ECO:0000255|HAMAP-Rule:MF_00413}.
CC   -!- PATHWAY: tRNA modification. {ECO:0000255|HAMAP-Rule:MF_00413}.
CC   -!- SUBUNIT: Interacts with IscS. {ECO:0000255|HAMAP-Rule:MF_00413}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00413}.
CC   -!- SIMILARITY: Belongs to the sulfur carrier protein TusA family.
CC       {ECO:0000255|HAMAP-Rule:MF_00413}.
