TRNA sulfurtransferase

In enzymology, a tRNA sulfurtransferase (EC number|2.8.1.4) is an enzyme that catalyzes the chemical reaction

:L-cysteine + 'activated' tRNA $ightleftharpoons$ L-serine + tRNA containing a thionucleotide

Thus, the two substrates of this enzyme are L-cysteine and 'activated' tRNA, whereas its two products are L-serine and tRNA containing a thionucleotide.

This enzyme belongs to the family of transferases, specifically the sulfurtransferases, which transfer sulfur-containing groups. The systematic name of this enzyme class is L-cysteine:tRNA sulfurtransferase. Other names in common use include transfer ribonucleate sulfurtransferase, RNA sulfurtransferase, ribonucleate sulfurtransferase, transfer RNA sulfurtransferase, and transfer RNA thiolase.
