Enzyme Commission Primary Name: tRNA sulfurtransferase
Enzyme Commission Synonyms: transfer ribonucleate sulfurtransferase, RNA sulfurtransferase, ribonucleate sulfurtransferase, transfer RNA sulfurtransferase, transfer RNA thiolase
Enzyme Commission Summary:
A group of enzymes transferring sulfur to various nucleotides in a tRNA chain, producing residues such as 4-thiouridylate. With some enzymes mercaptopyruvate can act as sulfur donor.
