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