In enzymology, an arginyltransferase (EC 2.3.2.8) is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are L-arginyl-tRNA and protein, whereas its two products are tRNA and L-arginyl-protein.
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.
ADP-ribosylation is the addition of one or more ADP-ribose moieties to a protein. It is a reversible post-translational modification that is involved in many cellular processes, including cell signaling, DNA repair, gene regulation and apoptosis. Improper ADP-ribosylation has been implicated in some forms of cancer. It is also the basis for the toxicity of bacterial compounds such as cholera toxin, diphtheria toxin, and others.

Arginylation is a post-translational modification in which proteins are modified by the addition of arginine (Arg) at the N-terminal amino group or side chains of reactive amino acids by the enzyme, arginyltransferase (ATE1). Recent studies have also revealed that hundreds of proteins in vivo are arginylated, proteins which are essential for many biological pathways. While still poorly understood in a biological setting, the ATE1 enzyme is highly conserved which suggests that arginylation is an important biological post-translational modification.
