Protein
Mitochondrial tRNA-specific 2-thiouridylase 1
Organism
Drosophila melanogaster
Function
Catalyzes the 2-thiolation of uridine at the wobble position (U34) of mitochondrial tRNA(Lys), tRNA(Glu) and tRNA(Gln). Required for the formation of 5-taurinomethyl-2-thiouridine (tm5s2U) of mitochondrial tRNA(Lys), tRNA(Glu), and tRNA(Gln) at the wobble position. ATP is required to activate the C2 atom of the wobble base.
Similarity
Belongs to the MnmA/TRMU family.
