This enzyme belongs to the family of transferases, specifically the aminoacyltransferases. The systematic name of this enzyme class is L-arginyl-tRNA:protein arginyltransferase. Other names in common use include arginine transferase, arginyl-transfer ribonucleate-protein aminoacyltransferase, arginyl-transfer ribonucleate-protein transferase, and arginyl-tRNA protein transferase. It has 2 cofactors: mercaptoethanol, and Cation.
