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.
