| Accepted name: |
tRNA-5-taurinomethyluridine 2-sulfurtransferase |
| Reaction: |
a [protein]-S-sulfanyl-L-cysteine + 5-taurinomethyluracil34 in tRNA + ATP + reduced acceptor = a [protein]-L-cysteine + 5-taurinomethyl-2-thiouracil34 in tRNA + AMP + diphosphate + acceptor |
| Other name(s): |
MTU1 (gene name); SLM3 (gene name); MTO2 (gene name) |
| Systematic name: |
[protein]-S-sulfanyl-L-cysteine:tRNA (5-taurinomethyluracil34 2-O)-sulfurtransferase |
| Comments: |
The enzyme, found in mitochondria, catalyses formation of 5-taurinomethyl-2-thiouridine in the wobble position of mitochondrial tRNAGln, tRNALys and tRNAGlu. |
